Order Hair Drug TestThe hair drug test is a laboratory method used to detect prior drug use by analyzing drug compounds that become incorporated into the hair shaft over time. Because hair grows at a predictable rate, a sample can provide a historical record of exposure rather than a snapshot of recent use alone.
About Hair Drug Test in Gresham
Hair testing works by measuring drug residues that are deposited in the growing hair follicle and become trapped as the hair hardens.
As hair forms in the follicle, trace amounts of drugs and their metabolites circulating in the bloodstream can be incorporated into the developing strand. Once the strand emerges from the scalp, the deposited compounds remain relatively stable and are not easily removed by normal washing or grooming.
Laboratory analysis typically begins by cutting a small sample close to the scalp and then washing it to remove external contamination. The sample is segmented to correspond with periods of growth, and each segment is processed to release the trapped compounds for detection.
The window of detection depends on hair length and the rate of growth. A standard sample taken from the scalp can reflect a period of roughly ninety days, while body hair may offer a longer but less precisely timed record. Results are reported by the laboratory according to its established cutoff and confirmation procedures.
