How To Collect a Hair Specimen for a Hair Drug Test

People are surprised when they have their first hair drug test.  They are unsure of the procedure and are surprised by the amount of hair that must be collected.  To complete both a drug screen and a confirmation on a presumptive positive screen result, we need a hair sample that is approximately the width of a Sharpie marker.  Lengthwise, 1/2″ of hair equals 30 days.  A common hair test is for 90 days, so the hair must be at least 1 1/2″ in length.  ExperTox can test for longer periods of time – it all depends on the length of the Donor’s hair.

We decided to show you how it is done so there will be no surprises if you must have this type of test completed.  Check out our own Lou Ann Enis, Registered Nurse and Occupational Health Supervisor, as she walks us through the steps.
