Hair analysis is now recognized as a robust method for identifying alcohol and drug consumption. Hair captures a prolonged record of substances by encasing biomarkers within the expanding hair strand. Collected near the scalp, it provides around a 3-month detection period for alcohol and drugs. Hair collection is straightforward, minimally tampered, and easily transported.
Obtaining a 1.5-inch segment of approximately 200 hair strands (around the size of a #2 pencil) nearest the scalp yields 100mg of hair, optimal for both screening and verification. For EtG, additional screenings, or panels beyond 10, 150mg is preferred. It's suggested to weigh the sample using a jeweler’s scale. If scalp hair is missing, a comparable quantity of body hair may be used. Referring to head hair implies scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result follows four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the primary integration of a sample into a lab’s framework. This step verifies the sample's secure seal and proper shipment, assigns a random LAN (Laboratory Accessioning Number), and fills any extra data entry needed beyond the electronic chain of custody system.
Screening executes an initial preliminary examination for substance misuse. Though cost-efficient for ruling out drug presence in most samples, a positive screening result requires subsequent confirmation to hold up in a legal setting. Any presumptively positive samples in Screening need further confirmation.
If a sample is presumed positive during Screening, additional hair is drawn from the original sample for Extraction. In this phase, drugs are extracted from hair at notably lower concentrations than other techniques (e.g., urine or oral fluid), making hair drug screening the most complex methodology.
Positive screening verifications proceed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples undergo washing prior to confirmation as deemed necessary. The comprehensive lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.
