Can I request a hair follicle drug test instead of a urine test?

Yes, Odosek Lab Solutions offers hair follicle drug testing as an alternative or supplement to urine testing. Hair follicle tests are particularly useful when a longer detection window is needed. While urine tests typically detect drug use within the past 1–3 days (or up to 30 days for frequent marijuana users), hair follicle tests can detect drug use over the past 90 days. The test requires a small hair sample (approximately 1.5 inches), typically collected from the head. If head hair is unavailable, body hair may be used. Hair follicle testing is often used for pre-employment screening, legal cases, and situations where a longer history of drug use needs to be established. Note that hair tests cannot detect very recent drug use (within the last 5–7 days) as it takes time for drugs to be incorporated into the hair shaft.
