Hair testing is increasingly recognized as an effective means for identifying the use of drugs and alcohol. Hair captures a prolonged record of substances by embedding biomarkers within the fibers as the hair strand grows. When gathered near the scalp, hair can reveal details of alcohol and drug consumption for up to a 3-month duration. Collecting hair is straightforward, relatively hard to tamper with, and simple to transport.
A sample of 1.5 inches comprising about 200 hair strands (about the diameter of a #2 pencil) nearest the scalp provides 100mg of hair, deemed the ideal sample size for initial analysis and verification. For EtG add-ons, or evaluations exceeding 10-panel tests, a 150mg specimen is advisable. It's beneficial to weigh the sample using a jeweler’s scale. If scalp hair isn’t accessible, an equivalent amount of body hair may be used. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other hair forms (facial, armpit, etc.).
Process Overview
The process of handling a drug test result in the laboratory consists of four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning deals with the initiation of a sample's journey into a laboratory’s procedure. This step ensures the sample was properly sealed and dispatched, assigns it a random LAN (Laboratory Accessioning Number), and finishes any remaining data requirements absent in an electronic chain of custody system.
Screening entails an initial swift assessment for drug misuse. As a cost-effective way to mostly exclude drug consumption, a positive result in Screening must be verified for legal admissibility. Any samples yielding a presumptively positive result in Screening necessitate further confirmation.
For samples with a presumptive positive result in Screening, additional hair is drawn from the initial collection and prepared for Extraction. During this phase, drugs are isolated from hair at significantly lesser concentrations compared to other techniques (e.g., urine or oral fluid), which contributes to hair drug screening being one of the most challenging methodologies to execute.
Confirmation for any positive screening outcome is handled via GC/MS, GC/MS/MS or LC/MS/MS. All samples showing presumptive positivity are cleansed before confirmation, as necessary. The overarching laboratory practice from Accessioning to Confirmation undergoes review under the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.
