Hair examinations are increasingly regarded as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and drug use by embedding biomarkers within the fibers of the developing hair strand. When collected near the scalp, hair can offer up to approximately a 3-month timeframe for detecting alcohol and other drugs. Hair is straightforward to gather, somewhat challenging to tamper with, and convenient to transport.
A 1.5-inch segment consisting of around 200 hair strands (about the size of a #2 pencil) nearest to the scalp provides 100mg of hair, the optimal sample for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is suggested. It is advisable to weigh the specimen using a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair may be collected. Reference to head hair pertains strictly to scalp hair. Body hair denotes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial processing of a sample within a laboratory’s framework. This step ensures the sample was adequately sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry absent from an electronic chain of custody system.
Screening serves as an initial rapid assessment for drugs of abuse. While Screening is a budget-friendly approach to exclude drug use in the majority of samples, a positive screen necessitates confirmation for courtroom admissibility. Samples with presumptive positive results in Screening require secondary verification.
If a sample is indicated as presumptive positive during Screening, additional hair is extracted from the initial sample and prepared for Extraction. During this phase, drugs are isolated from hair at a much lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening the most intricate methodology to execute.
Confirmation of any positive screen outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation if needed. The complete laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
