Hair screening is increasingly recognized as a robust method for identifying drug and alcohol usage. Hair can capture long-term usage patterns by retaining biomarkers within the fibers of its growing strands. When clipped near the scalp, hair delivers up to around a 3-month window of detection for alcohol and other substances. Hair collection is straightforward, hard to tamper with, and convenient for transportation.
A sample measuring 1.5 inches with roughly 200 hair strands (about the size of a #2 pencil) nearest the scalp yields 100mg of hair, which is the perfect quantity for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advised. It's suggested to measure the sample using a jeweler’s scale. Should scalp hair not be available, an equivalent amount of body hair can be obtained. By head hair, we specifically mean scalp hair. Body hair includes all other hair (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test outcome encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample into the laboratory’s framework. This step verifies the sample was sealed and transported appropriately, allocates a random LAN (Laboratory Accessioning Number), and finalizes any remaining data entry absent from an electronic chain of custody system.
Screening is an initial rapid evaluation for drug abuse. While a cost-effective method to identify drug use in most samples, any positive screen necessitates confirmation for legal admissibility. Samples showing a presumptive positive result in Screening need a follow-up confirmation.
If a sample indicates a presumptive positive during Screening, additional hair is extracted from the initial sample and prepared for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations than other methods (such as urine or oral fluid), marking hair drug screening as the most complex methodology to execute.
Confirmation of any positive screening result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples undergo washing as required prior to confirmation. The complete laboratory procedure from Accessioning to Confirmation is checked under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
