In Greenbriar, Virginia, Accredited Drug Testing offers thorough hair follicle drug examinations. With a specialization in hair drug and alcohol evaluations, we have facilities nationwide to conduct these tests. Typically, 1.5 to 2 inches of hair from the head or body suffices for analyses tailored to drugs, alcohol/ETG, or specific needs.
Hair follicle testing has surged in preference for drug screenings, surpassing urine tests as the top choice for employers, legal entities, and substance abuse experts. Those enforcing zero-tolerance policies benefit from its extended detection period of up to 90 days and the difficulty it presents to tampering, though recent drug use—within 5 days—is still best verified by urine analysis.

Hair analysis is recognized as a robust tool for uncovering drug and alcohol consumption. Hair can offer an extended history of substance use by encapsulating biomarkers within the fibers of the developing hair strand. When sampled near the scalp, hair can reveal substance use over about a 90-day period. The collection of hair is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch segment of approximately 200 strands of hair (roughly the width of a #2 pencil) closest to the scalp yields 100mg, which is the optimal quantity for both screening and confirmation. For EtG, additional tests, and screenings beyond 10 panels, a collection of 150mg of the hair sample is advised. We suggest using a jeweler’s scale for accurate measurement. If scalp hair cannot be gathered, a similar amount of body hair can be utilized. The term head hair specifically denotes scalp hair, whereas body hair encompasses all other types (including facial, axillary, etc.).
Process Overview
The laboratory handling of a drug test involves four critical steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the initial inclusion of a sample into the lab's database. This step ensures that the sample is secured and dispatched correctly, assigns a unique LAN (Laboratory Accessioning Number), and incorporates any data entry not already covered by an electronic chain of custody protocol.
Screening entails an initial, rapid assessment for drug abuse. While Screening is a cost-efficient means to exclude drug usage for most samples, a positive screen must be validated for court purposes. Presumptive positives during Screening mandate a confirmatory follow-up.
For samples flagged as presumptively positive during the Screening phase, additional hair is extracted from the original specimen and made ready for Extraction. This process retrieves drugs from hair at significantly lower concentrations compared to other procedures (such as urine or oral fluid tests), making hair drug screening a notably complex method.
Confirmation of any positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS techniques. To assure accuracy, all samples marked as presumptive positives are cleansed before confirmation as needed. The full laboratory cycle from Accessioning to Confirmation is governed by the CAP (College of American Pathologists) Hair criteria as well as ISO / IEC 17025 accreditation standards.
