In drug testing cases with judicial implications or times when you seek longer-term, extremely accurate results ARCpoint Labs of Mesa, AZ offers hair testing. Do to the ease of collection and longer term results, a hair drug test is ideal for safety-critical positions and zero-tolerance environments.

Once drugs enter the body, they travel through the bloodstream, eventually entering the hair shaft. A pencil-sized hair strand sample can be collected to test for drug use.

Hair drug test key features:

  • A hair test most accurately detects drug use within a 14 to 90-day detection window
  • Hair testing is ideal for chronic drug use
  • Results returned within 3-5 business days
  • There are no proven ways to falsify a hair drug test

Hair Test Procedure

At our many labs nationwide, a hair drug test is actually quite simple and requires only a small volume of hair preferably taken from the crown of the head.

The hair is cut as close to the scalp as possible, and it is put into a chemical solution to rid the hair of all external contaminants. It is then liquefied and tested for the presence of drugs.

Hair Test Detection Window

In most cases, hair sample drug testing can detect drug use for up to 90 days after use. The detection window is much longer in hair drug testing because trace amounts of drug chemicals become trapped inside each hair.

Like fingernail testing, hair is composed of a hard protein called keratin and is tested using the same process as fingernails. Drugs are incorporated into the hair’s fibers from the bloodstream and remain locked in the hair as it grows.
