Hair analysis is recognized as an effective means for identifying drug and alcohol consumption. Hair serves as a prolonged historical record by encapsulating biomarkers within its growing fibers. Samples obtained near the scalp can offer a detection period for alcohol and other drugs of roughly three months. Hair collection is straightforward, relatively resistant to tampering, and convenient to transport.
A sample size of 1.5 inches containing about 200 hair strands (comparable to the thickness of a #2 pencil) from near the scalp provides 100mg of hair, which is the optimal amount for testing. For the EtG test, additional panels, or tests exceeding 10-panel screening, a 150mg sample is advisable. It is suggested to weigh the sample using a jeweler's scale. In the absence of scalp hair, body hair may be utilized in equivalent amounts. The term head hair specifically refers to scalp hair alone. Body hair encompasses other types such as facial and axillary hair.
Process Overview
The key phases in laboratory processing for drug testing entail Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to inserting a sample into the laboratory's system. This step ensures the sample's proper sealing and shipment, assigns a random Laboratory Accessioning Number (LAN), and completes any necessary data entry not covered by an electronic chain of custody.
Screening provides an initial assessment for drug presence. This cost-effective approach can exclude drug use in most samples; however, any positive result requires confirmation for legal admissibility. Presumptive positives during Screening need further confirmation.
When Screening identifies a presumptive positive, additional hair is extracted from the primary sample for the Extraction phase. Drugs are retrieved from hair at lower concentrations than in other methods (e.g., urine or saliva), making hair drug testing particularly challenging.
Positive Screening results are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo washing before Confirmation if necessary. The process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.
