What is Hair Drug Testing?

After years of administering oral fluid and urine drug tests, we  have expanded to include hair drug testing.  The addition was made to aid companies and individuals who are looking for a different type of drug testing.

Standard drug testing at most, will show a history of drug use for a few weeks, usually only a few days, or even a few hours, depending upon the type of drug test administered (ie. urine or oral fluid).  For many people this is simply not good enough.  After many requests asking for a longer timeline for drug use, we have implemented hair drug testing.

So the question is what is hair drug testing, and what makes it different?

To begin, let’s examine  “what hair testing is”.

Hair drug testing, uses a 1.5” (3.8cm) section of hair, typically taken from the crown of the head, to check for drug use.  In cases where head hair is not available, body hair may also be used.  The sample is then stored in a foil in a dark, dry area, until it is sent to a lab.  At the lab the hair is “washed” in order to remove external contaminants.  The sample then undergoes, several distinct processes, including, immunological, gas chromatography, liquid chromatography and capillary electrophoresis.

Through this analysis, the detection of the use of the following drugs is possible . . .

Opiates (includes Morphine & Heroin)
Cocaine
Amphetamines (including methamphetamines)
Cannabinoids (THC, Marijuana)

Results for a hair drug test, on average are available anywhere from 24 hours, to 4 business days, depending on whether or not drugs are detected.  (Negative results are available more quickly then positive results)

After realizing what hair drug testing is, the need to know what makes it different arises.

  • Hair Drug Tests Cannot be Adulterated!
  • Hair Drug Test are Non-Invasive!
  • Drugs can be detected for up to 90 days on head hair samples, and up to 1 year on body hair samples.
