Hair testing is now acknowledged as a robust method for identifying drug and alcohol consumption. It offers an extended overview of drug and alcohol history by retaining biomarkers in the fibers of the hair strand as it grows. When taken from near the scalp, hair can deliver roughly a 3-month detection period for both alcohol and drugs. The collection process for hair is straightforward, relatively tamper-resistant, and convenient for shipping.
A sample of 1.5 inches, consisting of about 200 hair strands (similar to a #2 pencil's thickness) from the scalp, yields 100mg—considered the optimal amount for screening and confirmation. For EtG, additional tests, or panels beyond 10, a sample of 150mg is preferred. It's advisable to weigh the specimen using a jeweler's scale. If head hair isn't available, an equivalent quantity of body hair is acceptable. Head hair exclusively refers to scalp hair, while body hair includes all other types (such as facial or axillary hair).
Process Overview
The laboratory processing of a drug test involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of integrating a sample into the laboratory system. This phase ensures the sample was properly sealed and transported, assigns a LAN (Laboratory Accessioning Number) randomly, and handles any supplemental data entry that isn't covered by an electronic chain of custody system.
Screening performs an initial rapid assessment for drug abuse. While Screening is economically beneficial for ruling out drug use in most samples, any positive result in this phase requires confirmation to be valid in a legal context. Samples preliminarily positive in Screening must undergo a confirmation test.
During Extraction, if the Screening stage results are positive, additional hair is extracted from the original sample. Drugs are then extracted from hair at significantly lower concentrations compared to other methods (such as urine or oral fluids), which makes hair drug screening a challenging methodology.
Confirmation of positive results from Screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Samples with presumptive positive outcomes undergo a washing process as required before confirmation. The complete laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and through ISO / IEC 17025 accreditation standards.
