Hair testing is increasingly recognized as an influential method for identifying drug and alcohol consumption. Hair acts as a repository for long-term biomarker history, capturing evidence of usage within the growing strand fibers. With samples collected near the scalp, hair offers a detection period for substances like alcohol lasting up to three months. It is easy to collect, somewhat challenging to tamper with, and straightforward to transport.
A hair sample measuring 1.5 inches, containing roughly 200 strands (comparable to a #2 pencil), yields about 100mg of hair, which is ideal for both preliminary screening and confirmation. For EtG, additional tests, or when exceeding 10 panels, a 150mg sample is suggested. It is advisable to measure the specimen using a jeweler’s scale. If scalp hair is not accessible, a similar amount of body hair may be used. "Head hair" refers strictly to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processes a drug test result through four stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where the sample is integrated into the laboratory’s system, ensuring it was sealed and dispatched correctly, assigning a LAN (Laboratory Accessioning Number), and finalizing any extra data entry not included in an electronic chain of custody.
Screening performs a preliminary assessment for substance misuse. While this is a cost-efficient method to exclude drug consumption in most samples, any positive findings in Screening need verification for court acceptance. Any samples that preliminarily test positive in Screening require further confirmation.
Following a presumptive positive in Screening, additional hair from the primary specimen undergoes Extraction preparation. In this stage, substances are extracted from hair in significantly lower concentrations compared to other techniques (e.g., urine, oral fluid), which contributes to the complexity of hair drug screening.
Confirmation of positive Screening results utilizes GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation as deemed necessary. The complete procedural path from Accessioning through Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
