Studies from Forensic Fluids Laboratories in the Area of Toxicology Described (Qualitative and quantitative determination of xylazine in oral fluid).

A recent report from Forensic Fluids Laboratories in Kalamazoo, Michigan discusses the detection of xylazine, a dangerous adulterant in illicit fentanyl use, in toxicology panels. The researchers developed methods for the screening and quantitation of xylazine in oral fluid, which is a popular testing medium due to its ease of collection and reflection of presence in blood for many classes of drugs. The study validated the method and confirmed xylazine concentrations in living human subject oral fluid samples ranging from 1.2 to 23.3 ng/mL. This research provides valuable insights into the detection and quantification of xylazine in toxicology testing. [Extracted from the article]
