Hair Follicle Drug Testing
Hair testing provides a detection window of 90-days for drug use history that starts with a few strands of hair by hair analysis. Anyone can collect a qualified sample - anywhere, anytime.
Receive highly accurate, quantitative data on drug use for up to 90 days prior to the test date while reducing concerns of sample adulteration. All without handling oral fluids or urine.
- Highly accurate results - can detect up to 3 times as many positive users than urine
- More resistant to adulteration than urine - washing hair will not "dilute" sample
- Provides a 90-day history of drug use - demonstrating long-term drug use
- Yields significantly more information than urine, which only detects usage within last 3 days
Use this screening method for history of substance abuse, not for current or "under the influence" use detection.
