Hair analysis is increasingly recognized as an effective method for uncovering drug and alcohol consumption. By embedding biomarkers within the strands as hair grows, it offers a comprehensive record of substance use. When obtained near the scalp, hair can offer a detection window for drugs and alcohol spanning up to around three months. It's easy to gather, challenging to tamper with, and convenient for shipping.
A sample of 1.5 inches comprising roughly 200 hairs (comparable to the diameter of a #2 pencil) adjacent to the scalp yields 100mg of hair, which is the preferred quantity for preliminary and confirmatory testing. For EtG, add-ons, or tests surpassing ten panels, a 150mg specimen is suggested. Using a jeweler’s scale for specimen weighing is advised. In the absence of scalp hair, a comparable amount of body hair may be used. The term head hair pertains strictly to scalp hair. Body hair includes all other hair types such as facial or axillary hair.
Process Overview
The key stages in processing a drug test in the lab encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the first handling of a sample within a lab. This phase ensures that the sample is properly sealed and shipped, allocates a random LAN (Laboratory Accessioning Number), and completes data entry not automatically populated by an electronic custody chain system.
Screening is a preliminary assessment to detect drug use. Though cost-effective for mostly ruling out drug use, positive results here must be confirmed for legal credibility. Presumptive positives from Screening require verification through further testing.
If the Screening yields a presumptive positive, additional strands are harvested from the original batch for Extraction. This process involves isolating drugs from hair at lower concentrations than other methods (e.g., urine or oral fluids), contributing to the complexity of hair drug screening.
Confirming positive screenings involves GC/MS, GC/MS/MS, or LC/MS/MS. Necessary presumptive positive samples undergo washing prior to confirmation. The lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair standards and the accreditation to ISO / IEC 17025 standards.
