Hair testing is now recognized as a potent method for identifying alcohol and drug usage. Hair captures biomarkers within the fibers of a growing strand, providing a long-term record of alcohol and drug intake. By collecting hair close to the scalp, it can reveal a detection window of up to around three months for drugs and alcohol. Hair collection is straightforward, challenging to tamper with, and convenient for shipping.
A sample of 1.5 inches consisting of approximately 200 strands of hair (equivalent to the diameter of a #2 pencil) nearest to the scalp will weigh about 100mg, which is the optimal amount for screening and confirmation. For EtG, additional tests, and/or when testing beyond 10 panels, a 150mg sample is suggested. We advise using a jeweler's scale for weighing the sample. Should scalp hair be unavailable, collecting an equivalent quantity of body hair is acceptable. When we refer to head hair, it specifically pertains to scalp hair. Body hair includes all other types (e.g., facial, axillary, etc.).
Process Overview
There are four essential steps in processing a drug test result in the laboratory: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial processing of a sample into the lab's system. This step ensures the sample is properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry lacking from an electronic chain of custody.
Screening involves a preliminary fast check for drugs of abuse. Although Screening offers a cost-effective strategy to rule out drug use in most samples, a positive result requires confirmation for legal admissibility. Any samples with a presumptive positive in Screening necessitate further confirmation.
For samples flagged presumptively positive during Screening, additional hair is taken from the original sample and prepared for Extraction. During Extraction, drugs are extracted from hair at lower concentrations compared to other methods (e.g., urine, oral fluid), making hair drug screening particularly challenging.
Confirmation of any positive finding is done using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo a wash before confirmation if required. The complete laboratory process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

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