Hair Drug Testing
What is Hair Drug Testing?
Since hair growth is fed by the bloodstream, the ingestion of drugs of abuse is revealed by analyzing a small sample of hair. Our testing method measures the drug molecules embedded inside the hairshaft, eliminating external contamination as a source of a positive test result. Hair testing results cannot be altered with shampoos or other external chemicals.

What time period does a standard test cover?
A standard screen covers a period of approximately 90 days. The hair sample is cut as close to the scalp as possible and the most recent 1.5 inches are tested.

How much hair is needed?
A standard screen with GC/MS confirmation requires 60+ milligrams of hair or approximately 90 to 120 strands. The thickness of different types of head hair (thick coarse vs. thinning fine) is the reason for this variation.

How does Hair Testing compare to urinalysis?
The primary differences are
1) wider window of detection
2) inability to tamper with the test

Advantages: Hair drug testing can provide a much longer window of detection, which is useful for highly safety critical positions where there is zero tolerance of drug usage. Even if the person being tested has a shaved head (perhaps in preparation for the test), hair can also be taken from almost any other area of the body. This includes the underarms, arms, legs, and pubic area.

Disadvantages: Costs more than urine testing, must have a lab for results.

Compliance Safety Systems can arrange Hair tests for your firm as we employ 3 laboratories that perform these tests and have a database that contains a nationwide network of collection sites that are trained in collecting hair samples.
