As a highly effective method for identifying substance and alcohol consumption, hair testing has gained recognition. Hair captures biomarkers within the fibers of its growing strands, offering extensive information on drug and alcohol use. Collecting hair samples near the scalp can yield a detection window of up to three months for alcohol and other substances. The collection process is straightforward, the potential for tampering is reduced, and shipping is convenient.
To obtain the optimal sample for screening and confirmation, a 1.5-inch segment consisting of approximately 200 hair strands (comparable to the thickness of a #2 pencil) should be collected closest to the scalp, equating to 100mg of hair. For EtG, additional analyses, or tests exceeding 10 panels, a specimen weighing 150mg is suggested. Using a jeweler’s scale to weigh the specimen is advisable. If scalp hair is not accessible, an equivalent quantity of body hair can be used. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other types (e.g., facial, axillary).
Process Overview
The laboratory handling of a drug test result consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed within the laboratory’s system. This step includes confirming proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and concluding any additional data entry absent from an electronic chain of custody.
Screening serves as an initial expedient assessment for drug misuse. Screening provides a cost-effective strategy to exclude drug presence in most samples, although a positive result requires confirmation for court admissibility. Samples testing presumptively positive during Screening must undergo a subsequent confirmation process.
When a sample returns a presumptive positive in the Screening stage, additional hair is taken from the initial sample for preparation in the Extraction phase. This stage involves extracting drug traces from hair, which occurs at much lower concentrations than in other methods (e.g., urine or oral fluid), rendering hair drug testing the most complex methodology to execute.
Confirmation of any positive screening findings is conducted utilizing GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, all presumptive positive samples undergo washing as required. The comprehensive laboratory process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
