Hair analysis is recognized as a robust method for identifying drug and alcohol consumption. Hair encases a long-term record of alcohol and drug use by capturing biomarkers within the hair fibers as they develop. When sampled near the scalp, hair can indicate alcohol and drug use over a detection window of up to around three months. Collecting hair is straightforward, somewhat resistant to tampering, and simple to transport.
A 1.5-inch sample consisting of roughly 200 hairs (similar in thickness to a #2 pencil) nearest to the scalp will yield 100mg, which is the ideal amount for testing and verification. For EtG testing, additional tests, and tests exceeding 10 panels, a sample of 150mg is advised. It's beneficial to use a jeweler’s scale to weigh the sample. If scalp hair is not accessible, the equivalent quantity of body hair may be utilized. When discussing head hair, we refer exclusively to scalp hair, while body hair indicates all other hair types (e.g., facial, underarm).
Process Overview
The laboratory analysis of drug test samples involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing in a laboratory’s system. This phase involves checking that the sample was properly sealed and dispatched, assigning a LAN (Laboratory Accessioning Number), and completing any necessary data entry absent from an e-chain of custody.
Screening serves as an initial evaluation for substance abuse detection. While Screening is a cost-effective technique to eliminate drug use in most samples, a positive outcome from the screen requires confirmation in a court setting. Samples presumed positive in Screening necessitate secondary verification.
If Screening suggests positivity, additional hair is obtained from the original sample for Extraction. In this phase, drug substances are retrieved from the hair at lower concentrations than other methods (like urine or saliva), making hair drug testing a challenging technique to execute.
Positives from Screening go through Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Pre-confirmation, all presumptive positive samples undergo washing as required. The comprehensive lab process from Accessioning to Confirmation is assessed under CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation.
