Hair analysis is now recognized as an effective method for detecting substance use. Hair offers an extensive history of alcohol and drug consumption by embedding biomarkers within the developing hair strand fibers. When gathered from near the scalp, hair can offer a detection window of up to about 90 days for both alcohol and drugs. It’s straightforward to collect, harder to tamper with, and simple to mail.
An ideal specimen for testing comprises a 1.5-inch portion of roughly 200 hair strands (approximately akin to a #2 pencil) nearest to the scalp, yielding 100mg of hair. For EtG, expanded panels, and evaluations beyond 10 panels, a 150mg sample is advisable. Measuring the specimen using a jeweler’s scale is recommended. If scalp hair can't be accessed, a similar body hair quantity is acceptable. "Head hair" strictly refers to scalp hair, while "body hair" covers all other types (such as facial or axillary hair).
Process Overview
The primary steps in processing a lab-based drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning introduces a sample into a lab’s system. It ensures the sample’s seal and shipment integrity, assigns a LAN (Laboratory Accessioning Number) at random, and completes any extra data entry not provided by an electronic tracking system.
Screening provides a preliminary assessment for substances. While Screening is cost-effective for eliminating drug use on most samples, confirmed results are needed for court admissibility. Any samples positive in Screening require further confirmation.
If initially positive in Screening, additional hair from the initial sample undergoes Extraction. During Extraction, drugs are eliminated from hair at concentrations considerably lower than other methods (like urine or saliva), making hair drug tests particularly challenging.
GC/MS, GC/MS/MS or LC/MS/MS technology confirms any positive Screening outcomes. As required, all initially positive samples are cleaned before confirmation. The complete process—from Accessioning to Confirmation—follows the CAP's (College of American Pathologists) Hair standards and complies with ISO / IEC 17025 accreditation.
