About Hair Drug Test in Walnut
Hair drug testing relies on the way certain substances and their breakdown products are deposited in the hair shaft as it grows.
As hair grows, trace amounts of drugs or their metabolites can become incorporated into the forming hair shaft. Because hair grows at a relatively steady rate, the location of a substance along the strand can correspond roughly to the period when use occurred.
The test typically requires a small sample, often about the thickness of a pencil, cut close to the scalp. The laboratory washes the sample, extracts the substances of interest, and analyzes them using methods such as immunoassay screening followed by confirmation with mass spectrometry.
Hair testing is valued for its longer detection window, which can span months depending on hair length. It is not a measure of impairment or current intoxication, and results should be interpreted by a qualified professional in the context of the individual's history.
