Hair Follicle Drug Testing
The longest look-back available: a single hair sample screens for repeated drug use over roughly the past 90 days. Lab-analyzed and certified by a licensed Medical Review Officer.
Urine tests only see the last few days. A hair follicle test reaches back about 90 days, making it the standard when you need evidence of a longer pattern rather than a single recent use. A small hair sample is collected at the test center, analyzed by an accredited lab, and every result is reviewed and certified by a licensed Medical Review Officer (MRO) before it reaches you.

When to Get Tested
Choose a hair test when you need to look back over months rather than days: for example when short-notice urine testing may miss a pattern, when documenting a longer clean period, or when a court or employer specifically requests hair analysis. Note that very recent use (the last 5–7 days) may not yet appear in the hair.
Understanding Your Results
Results post to your secure online account, usually in 1–2 business days after the lab receives your sample. A negative result means no drugs were detected above the cutoff over the look-back period; any non-negative is confirmed and reviewed by a licensed Medical Review Officer before release, so the finding you receive is verified. Results are 100% confidential and never billed to insurance.
