Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. By embedding biomarkers within the fibers of the growing hair shaft, hair offers a prolonged historical record of alcohol and other drugs. When taken near the scalp, hair can provide an estimated 3-month detection period for substances. Hair collection is straightforward, relatively resistant to tampering, and easily transportable.
Collecting a 1.5-inch segment of approximately 200 hair strands (comparable to a #2 pencil's width) closest to the scalp yields 100mg of hair, the preferred amount for analysis and confirmation. For EtG, add-ons, and tests exceeding 10 panels, 150mg of the sample is advisable. Measuring the sample with a jeweler’s scale is recommended. If scalp hair is not available, an equivalent quantity of body hair may be collected. References to head hair pertain specifically to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test involves four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary integration of a sample into a laboratory's system. This step includes verifying the sample's seal and proper shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data processing not accomplished by an electronic chain of custody system.
Screening entails an initial rapid assessment for drugs of abuse. Although cost-effective for eliminating drug usage in most samples, a positive screen needs confirmation for legal admissibility. Samples with a presumptive positive in Screening require a secondary confirmation.
For samples with a presumptive positive in Screening, additional hair is extracted from the primary specimen and readied for Extraction. In this stage, drugs are extracted from hair at significantly lower concentrations than other methods (ex. urine or oral fluid), making hair drug analysis one of the most complex methodologies to execute.
Confirmation of any positive screen result is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation as necessary. The entire laboratory process from Accessioning to Confirmation is reviewed according to both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards.
