Hair Drug Testing

Hair drug testing provides up to a 90-day detection window and is designed to identify habitual and periodic substance abuse as opposed to urine screens which must be administered much sooner after the drug intake has occurred to be effective. This method is less invasive than blood testing and results are legally and scientifically recognized and accepted as forensic evidence. A typical hair collection for testing involves only using about 100 strands of hair collected close to the scalp.
Hair Drug Testing works best with:
  • Court-ordered or random testing as well as pre-employment drug testing
  • Pre-employment drug testing
