A complete analytical process examines hair samples to establish the presence of seventeen distinct substances or metabolites. This technique provides a retrospective window into a person’s drug use historical past, sometimes spanning a number of months. As an example, such an evaluation may detect opioids, cannabinoids, amphetamines, cocaine, phencyclidine, and numerous prescription drugs, relying on the precise panel configuration.
The advantage of such a evaluation lies in its prolonged detection window in comparison with urine or blood exams. This supplies a extra thorough evaluation of potential substance use patterns. Traditionally, hair evaluation has been employed in forensic toxicology, office drug screening, and scientific settings to judge adherence to prescribed drugs or to observe people in substance abuse therapy packages. Its non-invasive nature and talent to offer long-term information contribute to its utility.
