Flow cytometry system, a device used to count and measure the physical fluorescent properties of live cells or other biological elements, is being developed to provide invaluable testing and interpretive testing to physicians for management of patients. In Roswell Park Cancer Institute in Buffalo, NY, data collected from the cytometer is transferred to a personal computer to distinguish cancer cells from normal cells. However, the lack of standardization has relegated the wide use of flow cytometry in cancer diagnosis., The development of instrumentation to measure the fluorescence of live cells in solution initiated the use of flow cytometry for oncology diagnostics. In the 1980s, enhancements such as the discovery [...]

Older individuals are more prone to sickness compared to their younger counterparts. This is explained by an age-related decline in immune function and the immunosuppressive effects of stressful events that are particularly common among elderlies, such as death of a loved one and relocation. Certain hormones such as cortisol are elevated during stress, so determining their levels using radioisotopes may be a way of detecting proneness to sickness. Flow cytometry may also be utilized to assess the number of immune cells. These laboratory procedures may be useful in the early identification of immunosuppression among elderlies., The combination of an aging immune system and a stress-inducing event can spell illness for elderly Americans. Newly emerging evidence suggests that elevated levels of selected hormones may signal a [...]

Flow cytometry is coming of age. Its roles in establishing or confirming difficult diagnoses and in therapeutic drug monitoring are recognized worldwide. Nevertheless, the clinical relevance of any new technology [...]
