Identified as a potent resource, hair testing is recognized for uncovering drug and alcohol consumption. By embedding biomarkers within the fibers of the hair strand as it grows, hair records extensive usage history. When sampled near the scalp, it can reveal drug and alcohol presence for a span of roughly three months. Collecting hair is straightforward, altering the sample poses some challenges, and it can be shipped with ease.
A specimen of 1.5 inches consisting of around 200 hair strands, equating to the thickness of a #2 pencil, nearest to the scalp yields 100mg of hair, which is optimal for analysis. For EtG, extras, or tests exceeding 10 panels, 150mg of hair is advised. We suggest determining the specimen’s weight using a jeweler's scale. If scalp hair cannot be obtained, an equivalent amount of body hair is acceptable. Head hair refers solely to scalp hair, whereas body hair encompasses all other types like facial and axillary.
Process Overview
The laboratory procedure for producing a drug test result encompasses four pivotal phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the primary integration of a sample into a lab's framework. It ensures that the sample was properly sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and finalizes any lacking data entry absent from an electronic chain of custody mechanism.
Screening represents the preliminary cursory examination for substance misuse. While it's an efficient method to dismiss drug activity in the bulk of the samples, a triumph in Screening demands affirmation for courtroom validity. Any samples found indicative of positives in Screening necessitate further corroboration.
Upon obtaining a presumptive positive in the Screening phase, additional hair is extracted from the initial specimen and readied for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), hence the complexity in executing hair drug screening.
Affirmation of any initially positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples identified as presumptive positives undergo a washing process before confirmation if required. The entire laboratory operation from Accessioning through to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and the accreditation corresponding to ISO / IEC 17025 benchmarks.
