EITS Investigative Services

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 hair shaft, eliminating external contamination as a source of a positive test result.

Hair testing results cannot be altered with shampoos or other external chemicals.
A standard test covers a period of approximately 90 days.
We provide hair drug testing for a wide variety of companies and are able to conduct in-office and mobile collections if needed.
