Hair analyses have gained recognition as an effective means of identifying drug and alcohol consumption. Hair retains a prolonged history of substance use by capturing biomarkers within the fibers of the developing hair strand. When sourced near the scalp, hair can offer roughly a 3-month detection period for alcohol and drug use. Collecting hair is straightforward, harder to tamper with, and convenient for shipping.
A 1.5-inch portion of around 200 hair strands (around the thickness of a #2 pencil) next to the scalp provides 100mg of hair, the optimal sample for both screening and confirmation. For EtG, additional tests, or evaluations beyond 10 panels, 150mg of the sample is suggested. We advise measuring the sample on a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair can be collected. When mentioning head hair, we refer exclusively to scalp hair. Body hair pertains to all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial handling of a sample within a laboratory's system. This step confirms that the sample was properly sealed and transported, assigns an arbitrary LAN (Laboratory Accessioning Number), and finalizes any supplementary data entry absent from an electronic chain of custody system.
Screening involves an initial assessment for abused drugs. Although Screening presents an economical method to dismiss drug use in most samples, a positive screen necessitates confirmation for legal acceptance. Any samples that are provisionally positive in Screening require secondary verification.
When a sample is provisionally positive in the Screening phase, more hair is extracted from the original sample and readied for Extraction. In this phase, drugs are extracted from hair at notably lower concentrations than in other methods (e.g., urine or oral fluid), defining hair drug testing as a challenging practice to execute.
Confirmation of any positive screen findings occurs using GC/MS, GC/MS/MS, or LC/MS/MS. All provisionally positive samples are cleansed before confirmation if necessary. The complete laboratory procedure from Accessioning to Confirmation is assessed following both the CAP (College of American Pathologists) Hair guidelines and the accreditation of ISO / IEC 17025 standards.
