Hair analysis has emerged as an effective method for identifying alcohol and drug usage. The hair captures biomarkers within its strands, offering an extensive timeline of substance use. When gathered near the scalp, it can detect substances for up to three months. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch portion, approximately 200 strands of hair (about the thickness of a #2 pencil) closest to the scalp, yields 100mg—the preferred amount for both initial and confirmatory testing. For EtG, additional testers, and/or panels exceeding 10 substances, 150mg of hair is advised. Utilizing a jeweler’s scale for measurement is suggested. In the absence of scalp hair, an equivalent volume of body hair is acceptable. When discussing head hair, we specifically mean scalp hair. Body hair encompasses other types like facial or axillary hair.
Process Overview
The drug test processing in a lab includes four key phases: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is first logged into the lab’s system. This process involves confirming the sample was sealed and dispatched correctly, allocating a random LAN (Laboratory Accessioning Number), and completing any data input not managed by an electronic chain of custody.
Screening is a preliminary examination to detect drug presence. Though Screening is a cost-effective method for dismissing drug use in most samples, a positive outcome requires validation for legal acceptability. Any samples with a preliminary positive in Screening need confirmation.
Should a sample test as presumptively positive at the Screening phase, additional hair is extracted from the original sample for Extraction. In this step, drugs are extracted from hair at significantly lower concentrations than with urine or oral fluid, making hair drug testing a challenging technique.
Any confirmatory results are verified via GC/MS, GC/MS/MS, or LC/MS/MS, with all presumptive positives being washed beforehand if necessary. The entire procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation requirements.
