The examination of hair samples to identify drug use over an extended period, typically up to 90 days, offers a distinct advantage in substance abuse detection. Individuals seeking such services often search for accessible locations providing collection and analysis within their vicinity. This testing methodology analyzes drug metabolites embedded within the hair shaft, providing a historical record of drug consumption.
The value of this testing lies in its ability to detect drug use beyond the detection window of urine or blood tests. Its extended look-back period is particularly useful in legal and employment contexts requiring a comprehensive history of abstinence. Historically, the development of this technology has significantly improved the accuracy and scope of substance abuse monitoring programs.
