The process of hair testing has gained recognition as a significant method for identifying drug and alcohol consumption. Hair serves as a long-term record of drugs and alcohol by embedding biomarkers within its growing strands. Collected from near the scalp, hair can reflect up to around a 3-month period for detecting alcohol and various drugs. The collection of hair is straightforward, relatively tamper-proof, and easy to transport.
Obtaining a 1.5-inch hair sample, approximately 200 strands, or the size of a standard #2 pencil, will yield about 100mg, considered optimal for screening and confirmation. For EtG, additional tests, or those beyond 10 panels, a specimen of 150mg is suggested. It's advisable to weigh the sample on a jeweler's scale. If scalp hair is not accessible, a comparable amount of body hair can be used. "Head hair" refers exclusively to scalp hair. "Body hair" includes all other types such as facial and axillary.
Process Overview
The laboratory steps for determining a drug test outcome involve Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the sample's initial integration into a laboratory's framework. This process verifies correct sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes data entry tasks that aren't covered by an electronic chain of custody system.
Screening serves as a preliminary evaluation for drug abuse indications. While this is a cost-efficient method to dismiss drug use on most samples, any positive results must be substantiated for court credibility. Positive samples from Screening will require additional confirmation.
Presumptive positivity in the Screening phase leads to additional hair extraction from the specimen for the Extraction stage. Here, drugs are isolated from hair, albeit at lower concentrations than methods like urine or oral fluid testing, which renders hair drug screening particularly complex.
Confirmation of positive results from screening utilizes GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are cleaned as required before confirmation. The full lab process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.
