Hair Testing


Experimenting or regular user?

A hair test is often referred to as a "lifestyle test" because it provides a long-term view of drug usage (as far back as 2 years). Hair test can provide information about what a person is using on a regular basis. A positive result from a hair test indicates the frequency of use and/or use of a large amount of an illegal drug.The hair test is 5-panel test with confirmation included. There is no on-site hair testing available. A negative result can be confirmed in 1-2 days while a positive result takes 2-3 days. Many screening facilities do not collect enough hair to ensure accurate results. SurScan carefully and strategically collects enough hair to avoid this problem.

Fact: On average, hair grows approximately ½ inch per month.

Therefore, each ½ inch of head hair provides a 30-day history of drug usage. The maximum hair test is 12 inches of head hair.
If no head hair is available, then body, arm pit or chest hair can be used.
Fact: Bleaches, shampoos and external contaminants have no impact on test results.
