About Hair Drug Test in Alvin
Hair drug testing relies on the fact that drugs circulating in the body are incorporated into the growing hair follicle and remain there as the hair lengthens.
The collection process is simple and non-invasive. A trained collector clips a small sample of hair close to the scalp, typically from the back of the head where growth is most uniform. The sample is then sent to a laboratory for analysis.
Laboratory analysis usually begins with washing the hair to remove external contamination, followed by digestion of the hair matrix and extraction of any drugs or metabolites present. The extract is then screened and confirmed using techniques such as immunoassay, gas chromatography-mass spectrometry, or liquid chromatography-tandem mass spectrometry.
The reporting window depends on the length of the hair sample. As a general guide, each half inch of hair corresponds to roughly one month of growth, so a standard sample can cover a period of approximately 90 days. The exact window and the substances included in the profile are defined by the ordering laboratory.
