About Hair Drug Test in Gresham
Understanding what a hair drug test can and cannot reveal helps you interpret results correctly.
Hair grows at a predictable rate, and drugs or their metabolites can become incorporated into the hair shaft through the bloodstream. As a result, a hair sample can reflect drug exposure over a window of roughly 90 days, depending on the length of the hair collected and the lab's specific protocol.
The collection process is straightforward and non-invasive. A trained collector cuts a small amount of hair close to the scalp, typically from the back of the head, where growth is most uniform. The sample is then sealed and sent to a laboratory for analysis. If head hair is insufficient, the lab may use body hair, though the detection window can differ.
Screening methods such as immunoassay are often used first, and any non-negative result is generally confirmed with a more specific technique like mass spectrometry. It is important to note that hair tests do not measure current impairment; they indicate whether a substance was present during the period of hair growth represented by the sample.
