Considered a powerful method, hair testing effectively identifies drug and alcohol consumption. By capturing biomarkers within the strands, hair offers a detailed timeline for substance use. Cut near the scalp, it can reveal drug or alcohol use over a roughly 3-month span. Hair is easy to gather, difficult to alter, and straightforward to transport.
A sample measuring 1.5 inches and including roughly 200 hairs (similar to a #2 pencil's thickness) from near the scalp will yield approximately 100mg of hair, an ideal sample size for screening and confirmation purposes. For EtG, additional tests, or those exceeding 10 panels, 150mg is advisable. It's suggested to utilize a jeweler's scale for measuring. If scalp hair isn't accessible, an equivalent quantity of body hair should be used. The term head hair refers exclusively to scalp hair, while body hair encompasses all other types (such as facial or axillary hair).
Process Overview
The drug testing process in a lab encompasses four essential phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails integrating a sample into the lab's system, ensuring it was appropriately sealed and transported, assigning a LAN (Laboratory Accessioning Number) randomly, and completing necessary data entry absent in an electronic chain of custody system.
Screening serves as a preliminary assessment for substances. Though cost-effective for dismissing drug use in most samples, any positive Screen results require validation for court admissibility. Presumptive positive results necessitate secondary confirmation.
Presumptive positives in the Screening phase see additional hair extracted from the sample for the Extraction phase. Drugs are extracted at much lower concentrations than alternative methods (like urine or saliva), making hair screening complex to execute.
Confirmation of positive results occurs via GC/MS, GC/MS/MS, or LC/MS/MS. Pre-confirmation washing of samples takes place as required. The complete process from Accessioning to Confirmation is overseen under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
