Hair testing is viewed as a robust strategy for identifying drug and alcohol usage. Hair carries a prolonged record of substance use by embedding biomarkers within the fibers of the hair strand as it grows. By collecting hair near the scalp, it offers roughly a 3-month detection window for alcohol and drugs. The collection of hair is straightforward, relatively resistant to tampering, and easy to transport.
A 1.5-inch segment with roughly 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the preferred sample for both screening and certification. For EtG, additional screenings, and/or tests exceeding 10 panels, a 150mg specimen is advised. It's suggested to weigh the specimen using a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair can be collected. References to head hair pertain solely to scalp hair, whereas body hair encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The four primary steps in processing a drug test result in the laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into the lab's workflow. This step confirms proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and handles any further data entry absent in an electronic chain of custody system.
Screening conducts an initial assessment for drug substances. While it's a cost-effective method to exclude drug use in most samples, a positive screen requires confirmation to be acceptable in court. Samples with presumptive positives from Screening need a secondary verification.
If a sample shows a presumptive positive at the Screening phase, further hair is extracted from the original sample and readied for Extraction. In this step, drugs are taken from the hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), marking hair drug screening as the most complex methodology.
Any positive screening outcomes are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed as necessary before confirmation. The complete lab process from Accessioning to Confirmation is supervised under both the CAP (College of American Pathologists) Hair designation and accreditation pursuant to ISO / IEC 17025 standards.
