Order Hair Drug TestThe hair drug profile is a laboratory analysis that detects evidence of drug use in a sample of hair. Because drugs and their metabolites circulate in the bloodstream and are incorporated into the growing hair shaft, a hair sample can provide a longer historical view of exposure than blood or urine alone. This profile is used in clinical, forensic, and workplace contexts where a broader window of detection is useful.
About Hair Drug Test in Normal
Hair testing relies on the way substances are deposited in the hair shaft as it grows.
As drugs enter the bloodstream, a fraction of the parent compound and its metabolites is taken up by the hair follicle and bound into the keratinized hair shaft. Once incorporated, those residues remain in the hair and can be detected by laboratory methods such as immunoassay screening followed by mass spectrometry confirmation.
The collection procedure is straightforward. A trained collector cuts a small sample of hair close to the scalp, typically from the back of the head where growth is most uniform. The sample is oriented and secured so the root end can be identified, then sent to the laboratory for washing, digestion, and analysis.
The reporting window depends on hair length. Scalp hair grows at roughly one centimeter per month, so a sample of a given length can reflect exposure over a corresponding period of weeks to months. Hair testing does not indicate the exact time or amount of use, and results should be interpreted alongside the donor's history and the laboratory's established cutoff concentrations.
