Hair testing measures the drug molecules embedded inside the hair shaft.  The non-intrusive collection of the hair sample, along with the inability of donors to adulterate or contaminate the specimen, make hair testing a desirable option to other drug testing methods.

  • Hair testing provides a longer history of drug exposure than any other testing method, making it an excellent tool for positions where there is zero tolerance for drug use.
  • The collected hair specimens are sent to the lab for analysis and reported to the MRO for review.
