Hair assessments are now viewed as an effective method for discovering drug and alcohol consumption. Hair offers an extensive record of alcohol and drug usage by encapsulating biomarkers within the fibers of the developing hair strand. When obtained near the scalp, hair can reveal up to a roughly 3-month timeline for alcohol and drug detection. Hair collection is straightforward, somewhat resistant to tampering, and convenient to transport.
A sample of 1.5 inches consisting of around 200 hair strands (approximately the width of a #2 pencil) closest to the scalp yields 100mg of hair, the optimal sample for screening and validation. For EtG, additional tests, and/or panels exceeding 10, a 150mg specimen is recommended. We advise using a jeweler’s scale for weighing the specimen. In instances where scalp hair isn’t accessible, an equal quantity of body hair may be used. When mentioning head hair, we specifically mean scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The four essential stages in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning deals with the initial integration of a sample into a lab’s system. This phase ensures the sample was correctly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any additional data entry absent from an electronic chain of custody system.
Screening provides an initial rapid examination for drug abuse. While Screening is an economical method to exclude drug presence in most samples, a positive result requires confirmation to stand in court. Any samples tentatively positive in Screening necessitate subsequent confirmation.
For samples tentatively positive in the Screening phase, additional hair is extracted from the primary specimen and prepped for Extraction. Here, drugs are removed from hair at a significantly lower concentration than in other methods (e.g., urine or oral fluid), attributing to the complexity of hair drug screening.
Confirmation for any positive screen is executed via GC/MS, GC/MS/MS or LC/MS/MS. Samples that are initially positive are cleansed prior to confirmation if needed. The entire lab procedure from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair designation and meets ISO / IEC 17025 standards.

Note: Frequently called "hair follicle tests", the test examines the hair strand rather than the follicle beneath the scalp.
