Hair analysis has emerged as a robust method for identifying drug and alcohol consumption. The hair captures biomarkers over time within its growing strands, offering an extended overview of drug and alcohol use. With samples obtained near the scalp, hair can reveal substance use over about a three-month span. Collection is straightforward, tampering is challenging, and transportation is convenient.
A 1.5-inch segment consisting of 200 hair strands, approximately resembling a #2 pencil, yields 100mg—the optimal amount needed for screening and confirmation processes. For EtG tests or screenings exceeding 10 panels, 150mg is preferred. It's advisable to measure the sample using a jeweler’s scale. In the absence of scalp hair, a comparable quantity of body hair can be collected. "Head hair" strictly refers to scalp hair here, while "body hair" includes all other types like facial and axillary hair.
Process Overview
The four primary phases in the laboratory evaluation of drug tests are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the sample's initial integration into the lab's system. This step ensures the sample is properly sealed and dispatched, assigns an arbitrary LAN (Laboratory Accessioning Number), and inputs any supplementary information absent from an electronic chain of custody.
Screening serves to briefly identify drugs of abuse. As a cost-efficient strategy, it helps eliminate drug use for most samples, yet any positive result necessitates further confirmation for legal legitimacy. Presumptive positives in the Screen require additional validation.
Upon encountering a presumptively positive outcome in Screening, additional hair is obtained from the initial sample for Extraction. Here, drugs are extracted from hair at relatively lower concentrations than methods like urine or oral fluid, which makes hair screening notably challenging.
A positive screening necessitates Confirmation through techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo a cleansing before Confirmation when necessary. The entire procedure from Accessioning to Confirmation is scrutinized per CAP (College of American Pathologists) Hair standards and conforms to ISO / IEC 17025 criteria.
