There are so many statements on hair/drug testing which are not accurate. The most utilized method of testing for drugs is thru
urine specimens. Unfortunately, urine can be adulterated. Hair testing does not have this problem. Many people will try to
perm their hair, cut it short, bleach or dye it - all to no avail. Hair/drug testing holds up in court!!!
Quest Diagnostics provides a "Drug Testing Index™" once a year. The current report can be seen at

Hair testing is a simple process. The donor just needs to show up at the collection site with a CCF (Custody and Control Form) and
a picture I.D. The collection process is quick and assures that the hair is, indeed, from the correct donor. Drug Test Consultants
will provide you with a hair collection kit (for collection site use) as well as the proper CCF. Several thousand collection sites
exist throughout the United States.
