According to US Customs and Border Protection, over 473,000 family units and 76,000 unaccompanied children were apprehended in 2019, a multi-fold increase from previous years. Thus, the number of children who may be eligible for humanitarian relief has increased significantly. For those claiming humanitarian relief, forensic medical evaluations performed by health professionals can provide critical evidence to bolster claims. In this cross-sectional, nationwide survey-in which we sought to characterize specialties, forensic training, capacity, and scope of humanitarian relief evaluations for immigrant children under eighteen-years-old-only 28 providers, half of whom were Child Abuse Pediatricians, reported performing humanitarian relief evaluations. The most common reported type of humanitarian relief evaluation conducted was for asylum. We found that the current training for forensic medical evaluations for humanitarian relief in pediatrics is likely varied not well-defined, and not pediatric-specific. In order to protect the rights of children who are eligible for humanitarian relief, pediatric and family medicine forensic medical evaluation training standards and curricula need to be developed; validated humanitarian relief screening tools need to be tested and utilized; and residents and attending physicians, including specialists with expertise in forensic evaluations, need to be actively recruited to perform these evaluations in collaboration with legal aid organizations., (Copyright © 2021 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

Background: The rate of suicide in the US has increased substantially in the past two decades, and new insights are needed to support prevention efforts. The National Violent Death Reporting System (NVDRS), the nation's most comprehensive registry of suicide mortality, has qualitative text narratives that describe salient circumstances of these deaths. These texts have great potential for providing novel insights about suicide risk but may be subject to information bias., Objective: To examine the relationship between decedent characteristics and the presence and length of NVDRS text narratives (separately for coroner/medical examiner (C/ME) and law enforcement (LE) reports) among 233,108 suicide and undetermined deaths from 2003-2017., Methods: Generalized estimating equations (GEE) logistic and quasi-Poisson modeling was used to examine variation in the narratives (proportion of missing texts and character length of the non-missing texts, respectively) as a function of decedent age, sex, race/ethnicity, education, marital status, military history, and homeless status. Models adjusted for site, year, location of death, and autopsy status., Results: The frequency of missing narratives was higher for LE vs. C/ME texts (19.8% vs. 5.2%). Decedent characteristics were not consistently associated with missing text across the two types of narratives (i.e., Black decedents were more likely to be missing the LE narrative but less likely to be missing the C/ME narrative relative to non-Hispanic whites). Conditional on having a narrative, C/ME were significantly longer than LE (822.44 vs. 780.68 characters). Decedents who were older, male, had less education and some racial/ethnic minority groups had shorter narratives (both C/ME and LE) than younger, female, more educated, and non-Hispanic white decedents., Conclusion: Decedent characteristics are significantly related to the presence and length of narrative texts for suicide and undetermined deaths in the NVDRS. Findings can inform future research using these data to identify novel determinants of suicide mortality., Competing Interests: The authors have declared that no competing interests exist.

Applications for asylum in the United States have increased significantly in the past decade, including those by children fleeing persecution. Pediatricians may serve as a resource for children seeking asylum by participating in specialized training and performing forensic medical evaluations for use in the legal process. A forensic medical evaluation comprises an interview to elicit a narrative of reported abuse, a psychological assessment, and/or a medical assessment. Evaluators document an impression of the consistency of medical and psychological findings with the trauma, which forms the legal basis for a child's asylum claim. This article provides guidance to pediatrician evaluators with an emphasis on an age- and development-specific approach to a forensic medical evaluation of children seeking asylum. Collaboration with primary care pediatricians and community partners about asylum evaluations is important to building support for immigrant children who have experienced trauma.

Abstract: Gradation of Disability in Human Body Injuries （hereinafter referred to as Gradation） has been released and used since January 2017, and has become the most widely used standard in forensic science practice. This paper calculates and rates the visual system evaluation provisions of the current domestic disability evaluation criteria represented by the Gradation which used the methods of Guides to the Evaluation of Permanent Impairment （hereinafter referred to as GEPI） issued by American Medical Association （AMA）. Through comparing, a good correlation between the provisions in Gradation and whole person impairment rating index in GEPI was shown. On the basis of this, suggestions are put forward to amend some provisions of Gradation, in order to provide reference for the revision and further improvement of domestic standards and provisions., Competing Interests: The authors of this article and the planning committee members and staff have no relevant financial relationships with commercial interests to disclose., (Copyright© by the Editorial Department of Journal of Forensic Medicine.)

Using a 2004 population-based survey of all US medical examiner and coroner offices, we examined the characteristics of offices accepting an infant death case and calculated the percentage of offices that had death scene investigation or autopsy policies for the investigation of sudden unexpected infant death (SUID). We also calculated the percentage of offices that used and did not use sudden infant death syndrome (SIDS) as a cause of death, and we compared differences in characteristics among those offices.Of medical examiner and coroner offices, 52% did not report an infant death in 2004. Of the 7957 infant deaths reported, 43% occurred in jurisdictions that experienced 1 or 2 infant deaths. Of the offices that used SIDS as a classification, 34% did not have policies for conducting death scene investigations and autopsies for SUID. At least 5% of offices that reported an infant death did not use SIDS as a cause of death classification. These findings have important implications for understanding recent trends in SIDS and SUID. Supporting the implementation of national standards for investigating and certifying infant deaths could provide guidelines for consistent practices in medical examiner and coroner offices.

The medical evaluation of children with suspected sexual abuse includes more than just the physical examination of the child. The importance of taking a detailed medical history from the parents and a history from the child about physical sensations following sexual contact has been emphasized in other articles in the medical literature. The examination is important, however, and medical providers who examine children need to be aware of published research on findings in nonabused children, studies of healing of injuries, and studies documenting the association between sexual contact and the diagnosis of sexually transmissible infections in children. This article reviews the current approach to interpreting findings in children who may have been sexually abused and why additional research is needed.

The National Academy of Sciences recommends that states assess the performance of medicolegal death investigation agencies. To aid in performance assessment, we adapted an instrument based on the CDC's 10 Essential Public Health Services by translating the terminology to that of essential medicolegal death investigation services. This produced a survey that could be used to standardize reporting practices and services of agencies. To validate the instrument, a stratified random sample of 12 death investigation chiefs in 12 states was interviewed. This sample represented both medical examiner and coroner jurisdictions within the varying medicolegal structures. A cognitive testing process elicited how well participants could respond to and interpret the survey questions. The response was favorable in that the respondents agreed that given specific revisions toward question clarification, the instrument would be a useful and relevant tool for assessing system performance., (© 2011 American Academy of Forensic Sciences.)

The appropriate imaging for pediatric patients being evaluated for suspected physical abuse depends on the age of the child, the presence of neurologic signs and symptoms, evidence of thoracic or abdominopelvic injuries, and whether the injuries are discrepant with the clinical history. The clinical presentations reviewed consider these factors and provide evidence-based consensus recommendations by the ACR Appropriateness Criteria(®) Expert Panel on Pediatric Imaging., (Copyright © 2011 American College of Radiology.

This review discusses the forensic medical and psychological assessments of children and adolescents suspected of being victims of sexual or physical abuse/neglect. Evaluation of the whole child and the need to minimize trauma during the investigative and assessment processes are stressed. The forensic medical examination is reviewed, including the specifics of the pediatric anogenital examination. The key components of the forensic medical examination in sexual assault cases are also reviewed, with particular attention to maintaining the integrity of the process. Special emphasis is placed on the forensic interview in child sexual abuse cases, the best evidence available and areas in need of further research.

Although proficiency test programs have long been used in both clinical and forensic laboratories, they have not found uniform application in forensic breath alcohol programs. An initial effort to develop a proficiency test program appropriate to forensic breath alcohol analysis is described herein. A total of 11 jurisdictions participated in which 27 modern instruments were evaluated. Five wet bath simulator solutions with ethanol vapor concentrations ranging from 0.0254 to 0.2659 g/210 L were sent to participating programs, instructing them to perform n = 10 measurements on each solution using the same instrument. Four of the solutions contained ethanol only and one contained ethanol mixed with acetone. The systematic errors for all instruments ranged from -11.3% to +11.4% while the coefficient of variations ranged from zero to 6.1%. A components-of-variance analysis revealed at least 79% of the total variance as being due to the between-instrument component for all concentrations. Improving proficiency test program development should consider: (1) clear protocol instructions, (2) frequency of proficiency testing, (3) use lower concentrations for determining limits-of-detection and -quantitation, etc. Despite the lack of a biological component, proficiency test participation should enhance the credibility of forensic breath test programs.

Increased interest in pursuing criminal and civil actions against alleged perpetrators of elder abuse and neglect has revealed that efforts to assist victims and hold perpetrators accountable are often hampered by the lack of knowledge about the detection and diagnosis of elder abuse and neglect and by the lack of resources for development of research and assistance in these matters. This report sets forth recommendations for the elder abuse, health, and justice fields about medical forensic issues related to elder abuse and neglect. The recommendations were developed by a "working group" of experts representing an array of disciplines that address the problem of elder abuse and neglect pursuant to a grant project funded by the National Institute of Justice (NIJ), the research, development, and evaluation agency of the U.S. Department of Justice (DOJ). The project was conducted by the American Bar Association Commission on Law and Aging, with the assistance of the University of California, Irvine School of Medicine. This was the final project report submitted to NIJ; it has been updated to include information about the availability of reports and products from other grant projects that are discussed in the report.

Forensic medicine belongs to a group of medical specialties which are listed as basic specialties according to the Ministry of Health. As indicated already by the specialist program, the aim of such studies involves mastering of abilities which permit the medical doctor to provide competent opinions for courts and other organs in the administration of justice, consistent with the current medical knowledge, forensic experience and requirements of the law. Therefore, obtaining specialist qualifications in forensic medicine the doctor is expected to be prepared for forensic certification in penal, civil and insurance matters on the basis of a medical examination and/or court files. It should be explained that forensic medicine practiced in Poland and in some European countries represents a much broader specialty than forensic pathology practiced in the USA and some English-speaking countries. In the latter countries the specialty represents a part of broadly understood pathology. The situation of a forensic physician in organization of the execution of justice in the USA, his/ her competencies and range of activities are completely distinct to those characterizing a forensic physician in Poland. In its range accepted in Poland, forensic medicine has a broader scope. It deals not only with the narrow range of penal proceedings but also pertains the entire problems of certification for the courts and other organs which deal with implementation of justice, as well as for other institutions such as various insurance companies. One of the reasons for separation of forensic medicine from other specialties was the fact that appropriate forensic opinioning requires more than encompassing respective medical knowledge. Also needed is the ability to understand intentions and aims of justice execution and the capacity to formulate opinions in such a range and in such a way that it will be perceived by the addressee in an unbiased form.

Sexual violence is a monumental problem in Kentucky and elsewhere, and healthcare providers play a critical role in its identification, treatment, and prevention. This article provides essential information for physicians treating survivors of sexual violence, including treatment options, protocol for medical-forensic examinations, tips for documentation, and information about community resources that can facilitate treatment outcomes and proide follow-up services.

This article is part of a special issue reflecting on what people have learned about violence and trauma over the past 20 years and where we need to go in the next 10 years. The author emphasizes the importance of learning to communicate in order to form effective community partnerships. Evidence-based research is noted as a methodological innovation for policy research. Looking to the future, the author suggests that it will be important for crime prevention researchers to not just rely on Internet-based library searches so that they may avoid problems of innumeracy and ahistoricism.

Violence against women (VAW) is a prevalent problem with substantial physical and mental health consequences throughout the world, and sound public policy is dependent on having good measures of VAW. This article (a) describes and contrasts criminal justice and public health approaches toward defining VAW, (b) identifies major controversies concerning measurement of VAW, (c) summarizes basic principles in identifying and measuring VAW cases, and (d) recommends changes to improve measurement of VAW. In addition to reviewing recommendations from the Centers for Disease Control and Prevention Workshop on Building Data Systems for Monitoring and Responding to Violence Against Women and the World Health Organization World Report on Violence and Health, the article concludes that changes are needed in the FBI Uniform Crime Reports and National Crime Victimization Survey to improve measurement of rape and sexual assault.

This article reviews the major forms of violence against women, including sexual assault, intimate-relationship violence, and stalking and outlines the known psychological effects of such victimization. Also discussed are a number of variables that combine to determine the effects of such victimization, including type and characteristics of the assault; victim variables such as demographics, psychological reactions at the time of the trauma, previous victimization history, current or previous psychological difficulties, and general coping style; and sociocultural factors such as poverty, social inequality, and inadequate social support. The implications of this complexity are explored in terms of psychological assessment and the frequent need for multitarget, multimodal treatment approaches.

This paper asserts that although there is considerable agreement in the U.S. and internationally about the importance of uniform terminology and measurement related to violence against women, we need a strategy for choosing standardized definitions and measures. Responding to Kilpatrick's comments at the October 2003 national research conference on violence against women, the author stresses the importance of developing and using uniform terminology related to violence against women, and discusses the lack of a formal mechanism to achieve uniformity of definitions and measurement. Uncertainty about the impact of context on survey findings and the lack of agreement about the optimal scope of measurement are discussed. The author also comments on some difficulties associated with implementing Kilpatrick's proposed modifications to existing measures of rape and sexual assault.

This article discusses (a) the relationship between the reemergence of the women's movement in the 1970s and the current field of violence against women; (b) the role voluntary associations and social activism play in shaping social institutions, including the institution of academic scholarship; (c) the need to broaden our definition of violence against women to include nonviolent acts, such as stalking and emotional abuse; (d) the need to study the interrelationships among various forms of violence and abuse, including violence and abuse experienced as a minor and violence and abuse experienced as an adult; (e) the importance of using precise language when reporting research findings; (f) the importance of using a multiple definition/measurement approach when conducting research on violence against women; and (g) the need for comprehensive research on violence against women that takes into account the various types of violent and abusive behaviors experienced by women over their lifetimes.

The National Association of Medical Examiners Committee on Cocaine-related Deaths recommends that the following guidelines be applied in the process of documenting, interpreting, and certifying potential cocaine-related fatalities. The committee cautions that the investigation of any drug-related death requires a complete investigation of the circumstances of death, the death scene, and past medical history. It is also necessary to have the results of the forensic toxicological analysis and those of a complete forensic autopsy examination prior to formulating an opinion as to the cause and manner of death. Cocaine should be considered the underlying cause of the death when 1 or more of the following is true: (1). the circumstances surrounding the death can be associated with an acute cocaine exposure and there are no supervening causes of death; (2). the immediate cause of death is directly due to a readily identifiable mechanism or disease such as a gunshot wound or a stroke, yet the acute use of cocaine was the direct underlying cause of the trauma or the disease process; and (3). chronic cocaine use leads to a disease that results in an ultimately fatal pathologic process leading to organ injury and death. The committee further cautions that reported drug levels may not directly relate to the toxic or lethal effects of the drug upon the patient. These guidelines are intended for use by practicing medical examiners and physicians who certify drug deaths, as well as providing education tools for students.

Walter McCrone was not only a remarkable forensic microscopist, but also a skilled grants man and devoted scientific professional. This article briefly recounts his activities in the 1970s and 80s where he played a major role in securing grant funds to sponsor microscopy training around the country, and in using his considerable professional influence to advance the cause of certification.

Combating bioterrorism is a challenge to all of us. To be proactive, the U.S. Government has formalized the discipline of "microbial forensics" to deter and attribute perpetrators of such acts. This Policy Forum describes the foundations of the microbial forensics program: the creation of a national bioforensics laboratory, a partnership laboratory network, and a peer-consensus scientific working group and the promulgation of quality assurance guidelines.

Eighteen laboratories interested in the analysis of human hair for drugs of abuse participated in a proficiency test (PT) organized by the Society of Hair Testing (SoHT) in 2001. Samples sent to the participants included one drug-free hair sample and two samples from drug users, sent in the form of short segments previously checked for homogeneity by three reference laboratories. Participants were requested to analyze the samples following the standard procedure used routinely in their laboratories.The compounds present in the samples included opiates, cocaine and metabolite, cannabinoids and amphetamines. All the laboratories analyzed opiates, cocaine and benzoylecgonine (BE); only 10 analyzed amphetamines, and 9 cannabinoids. Various methods were used to extract drugs from the hair-enzyme treatment, acidic, basic and methanol extractions. All the laboratories employed GC-MS, with the exception of two which used GC-MS/MS and LC-MS/MS, respectively. Six laboratories performed initial screening tests by RIA, ELISA or EMIT. Results show that the laboratories performed well qualitatively, since they successfully identified all the analytes that they tested, with the exception of eight false results. However, the scatter of quantitative results was high.

This article discusses the phenomenon of "context effects" by reviewing the findings and practices of a range of scientific fields, including astronomy, physics, biology, medicine, and especially the relevant research and theory from psychology. Context information, such as expectations about what one is supposed to see or conclude, has been found to have a small but relentless impact on human perception, judgment, and decision-making. The article then considers the vulnerability of forensic science practice to context effects, and concludes by suggesting that forensic science adopt practices familiar in other fields of scientific work, in particular blind or double-blind testing and also the use of evidence line-ups.

The background and goals of a national study to determine the feasibility of blind proficiency testing in U.S. forensic DNA laboratories are discussed. Part of the project involved designing and executing a series of fifteen blind proficiency tests. Execution included biological specimen donor recruitment and case evidence manufacturing. Simulated cases were submitted to DNA laboratories by law enforcement agencies and in some cases by other forensic-science laboratories. Replicate-manufactured evidence was submitted to reference laboratories to simulate the workings of a larger-scale program. Ten tests were straightforward, and essentially tested analytical ability. Five tests involved selecting on the basis of case facts appropriate bloodstains for typing from a bloodstain pattern. We describe in detail our experience in designing and conducting these blind proficiency test trials, and relate those experiences to the overall issue of blind proficiency testing as a quality-assurance tool in forensic DNA laboratories. In this feasibility test series, one blind test was detected by a laboratory, a second one was shown to the lab by law enforcement, and a third was never completed because of lapses in communication. Turnaround times were relatively fast in the independent/commercial labs and relatively slow in the larger public laboratories. Two cross-state case-to-case CODIS "hits" were "planted" among the first series of ten blind tests. One pair was detected. One member of the second pair went to a lab that was not CODIS-ready.

We describe the origins, purposes, and findings of a national study to determine whether a large-scale program of blind proficiency testing in U.S. DNA laboratories is feasible and/or practical. Proficiency testing in clinical laboratories is reviewed, particularly as mandated by the Clinical Laboratory Improvement Acts and its role in the regulation of those laboratories. Proficiency testing in forensic urine drug testing labs is also briefly reviewed. Studies involving comparisons between open and blind proficiency testing are discussed. The clinical laboratory proficiency testing and regulation landscape provides the background for the DNA Act of 1994, and the congressional mandate to investigate blind proficiency testing in forensic DNA laboratories. Four models of blind proficiency testing are defined and discussed, along with the advantages and disadvantages of each and estimates of the costs of a large-scale program. The purposes of proficiency testing in a quality-assurance context are likewise discussed and related to the models and the arguments generally proffered for and against blind vs. open proficiency testing.

Failure to collect evidence, inadequate care, and delays resulted in a New York City hospital being fined for providing inadequate care to a rape victim. These problems are common in the emergency department. Avoid asking sexual assault victims the same questions repeatedly. Determine the patient's primary concern and address it immediately. Examine patients in a private area with adequate space.

As DNA and RNA become major targets for clinical laboratory analysis, benchmark reagents will play an increasingly important role in standardization. Reliable national and international nucleic acid standards promote automation and third-party reimbursement for clinical testing. Furthermore, nucleic acid standards provide materials for quality assurance and quality control (QA/QC), and proficiency testing. Standard methods and training initially evolved from consensus guidelines endorsed by professional societies and governmental agencies. The National Institute of Standards and Technology (NIST), a nonregulatory agency of the U.S. Department of Commerce, develops and certifies physical and chemical standards in support of national commerce, manufacturing, and science. In its role supporting U.S. science and industry, the NIST responds to specific standards needs, most recently for medically and biologically important analytes. Broad-based consensus developed through interdisciplinary NIST workshops initiated development of NIST-certified DNA standards. Such materials serve the diagnostic community and help manufacturers benchmark a variety of DNA diagnostic testing platforms. Here we summarize the NIST experience and programs for development of national standards for DNA-based medical diagnostic testing., (Copyright 2002 Wiley-Liss, Inc.)

The unique culture of medical settings impacts the style, pace, and quality of psychological consultation provided in that setting. Matters of life and death and other health emergencies, relationships with the courts, and contact with severely impaired patients are typical events. Medical psychologists (MPs) share many, but not all, of the ethical values that guide provision of services by other medical professionals under such circumstances. This generates the need to develop an interdependent but independent ethical orientation on the part of MPs in all professional activities, including psychological assessment. In this article, background information is presented on values that frequently drive medical treatment that may conflict with the MPs' ethical standards. A model appropriate for use in situations requiring complex decisional processes is reviewed, and vignettes are presented as examples of bioethical problem solving under this systematic decisional framework.

Interpretation guidelines for short tandem repeat casework analysis are difficult to construct. As soon as a set of guidelines are developed, a new case evolves that does not fit the painstakingly written document. The casework analysts gather and amend the guidelines again, and again. This article seeks to demonstrate that general guidelines can be set and written such that it can be used for any detection format. Guidelines published by the Scientific Working Group for DNA Analysis Methods, a working group of DNA forensic experts in the United States, are used to set the format for the written protocol on interpretations. The rule "the interpretation of results in casework is a matter of professional judgment and expertise. Not every situation can or should be covered by a preset rule" is stressed. Development of minimum and maximum threshold values, heterozygote ratios, stochastic limits, and determination of major and minor components based on validation studies is discussed. The paper travels through setting criteria to evaluate internal lane standards and amplification controls. It continues with establishing ranges for interpretation and defining true alleles versus anomalies. Examples of a variety of profiles are given and the potential interpretation, using signal intensities and genetics. In addition, report writing strategies and wording routinely used by the Pennsylvania State Police DNA Laboratory System are given.

A compendium of human mitochondrial DNA (mtDNA) control region types has been constructed. This updated compilation indexes over 10,000 population-specific mtDNA nucleotide sequences in a standardized format. The sequences represent mtDNA types from the Scientific Working Group on DNA Analysis Methods (SWGDAM) mtDNA database and from the public literature. The SWGDAM data are considered to be of higher quality than the public data, particularly for counting the number of times a particular haplotype has been observed.

Forensic evidentiary samples routinely contain DNA from multiple contributors. The interpretation of these mixtures can be a challenging task for the DNA scientist. Several approaches are discussed (no calculation- qualitative statement; probability of exclusion; likelihood ratio estimates; presumptive genotype assignment based on peak heights), which have been employed to assess the significance of an inclusion/match when DNA mixtures have been detected in casework samples. These statistical approaches are discussed in light of technical challenges that can arise when evaluating evidentiary samples.

The National Center for Health Statistics (NCHS) is responsible for publishing Standard Certificates of Birth and Death for the United States of America. The standard certificates are revised roughly every 10 years. The revision process is designed to ensure that the standard certificates meet, as nearly as possible, the use for which they are intended at all levels: individual, local, state, and federal. The authors report on the most recent revision of the U.S. Standard Certificate of Death, recording the process and the role of the National Association of Medical Examiners in the process. Changes recommended during revision include requesting known aliases of a decedent and rearrangement of the certificate to provide more room for those items requesting dates and for describing how the injury occurred. New items have been added asking for information regarding traffic fatalities, the role of tobacco use in causing death, and whether female decedents were pregnant. Once approved by the Department of Health and Human Services, the new standard certificate will be made available to the states. Each state will have 2 years to adapt the U.S. Standard Certificate of Death to its use and to implement new state death certificates on January 1, 2003.

This article reviews the history of DNA-based human identification from its inception in 1985. Since the development of the technology, experts called for setting of standards and use of proficiency tests for quality assurance measures. The response of the National Institute of Standards and Technology to DNA forensic standards needs was catalyzed by the Technical Working Group on DNA Analysis Methods, sponsored by the Federal Bureau of Investigation with funding provided by the National Institute of Justice. Standard reference materials were developed for the original technologies used in DNA identification and for the newer polymerase chain reaction-based technologies. Adoption of recommended standards developed through the Federal Bureau of Investigation-commissioned DNA Advisory Board show the acceptance of National Institute of Standards and Technology standards for calibration of laboratory protocols. New technologies will require a process of validation and continued testing through the use of proficiency tests, such as those provided through the College of American Pathologists. Robotics and parallel processing of samples will lead to increased efficiency in DNA testing. The use of DNA data banks of convicted felons will increase dramatically with the the Federal Bureau of Investigation's national implementation of a computerized identification system known as the Combined DNA Index System. This system that will make major use of short, tandem, repeat genetic systems and will be the major driver of technology for the next 5 to 10 years. Finally, sample collection and training are of major concern for those who look at the long-term impact of DNA testing in forensic laboratories.

Knowledge of the expected uncertainty in restriction fragment length polymorphism (RFLP) measurements is required for confident exchange of such data among different laboratories. The total measurement uncertainty among all Technical Working Group for DNA Analysis Methods laboratories has previously been characterized and found to be acceptably small. Casework cell line control measurements provided by six Royal Canadian Mounted Police (RCMP) and 30 U.S. commercial, local, state, and Federal forensic laboratories enable quantitative determination of the within-laboratory precision and among-laboratory concordance components of measurement uncertainty typical of both sets of laboratories. Measurement precision is the same in the two countries for DNA fragments of size 1000 base pairs (bp) to 10,000 bp. However, the measurement concordance among the RCMP laboratories is clearly superior to that within the U.S. forensic community. This result is attributable to the use of a single analytical protocol in all RCMP laboratories. Concordance among U.S. laboratories cannot be improved through simple mathematical adjustments. Community-wide efforts focused on improved concordance may be the most efficient mechanism for further reduction of among-laboratory RFLP measurement uncertainty, should the resources required to fully evaluate potential cross-jurisdictional matches become burdensome as the number of RFLP profiles on record increases.
