Hair testing is recognized as an effective method for identifying alcohol and drug use. Hair fibers capture biomarkers, offering a long-term history of substance use. When collected near the scalp, hair provides a detection period of up to about three months for alcohol and drugs. It is straightforward to collect, somewhat resistant to tampering, and easy to transport.
A 1.5-inch segment of approximately 200 hair strands (about the size of a #2 pencil) closest to the scalp equals 100mg of hair, which is the ideal sample for analysis. For EtG, additional tests, and/or screenings exceeding 10 panels, 150mg of the sample is advised. It is recommended to weigh the sample with a jeweler’s scale. If scalp hair is absent, an equivalent amount of body hair can be used. When referencing head hair, it specifically means scalp hair. Body hair covers all other hair types (facial, axillary, etc.).
Process Overview
The four primary steps in the laboratory processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial incorporation of a sample into the lab’s system. This step includes ensuring the sample was sealed and sent correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not available through an electronic chain of custody system.
Screening provides a preliminary check for substance abuse. Although it is a cost-efficient way to rule out drug use in most samples, a positive screening requires confirmation to be valid in court. Any samples that indicate a positive result in Screening must undergo secondary confirmation.
If a sample shows a presumptive positive in the Screening phase, additional hair is taken from the initial sample and prepared for Extraction. In this phase, drugs are isolated from hair at significantly lower concentrations than other methods (such as urine or oral fluid), making hair drug screening the most challenging method to conduct.
Confirmation of any positive screening outcome is done via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed prior to confirmation as necessary. The entire lab process from Accessioning to Confirmation is validated under both the CAP (College of American Pathologists) Hair guideline and the accreditation to ISO/IEC 17025 standards.
