Hair Testing for a 90-Day Drug Use History

Hair Follicle Testing for drugs is the one way to get an in depth assessment of up to 90 days in the past to determine if someone has been using drugs. This is a great test for an employer or parent.

Simple specimen collection and highly accurate results meet the same reference standards as urine testing. In addition, there are no known methods for sample adulteration (hair washing will not dilute the sample). Because specimen collection can be directly observed, the risk of adulteration is even further reduced.

We get the results back to you quicker: Negative results are reported within 24 hours of receipt at the laboratory, and positive results are confirmed using gas chromatography/mass spectrometry (GC/MS) or gas chromatography/mass spectrometry/mass spectrometry (GC/MS/MS) within 48 to 72 hours. Hair testing is also forensically defensible.

When compared with urine specimen testing, hair testing provides up to 2.5 times the number of positives and a longer detection window.
