Hair testing is recognized as a potent method for identifying drug and alcohol consumption. Hair retains a comprehensive record of alcohol and drug use by embedding biomarkers in the strands as they develop. When harvested near the scalp, hair can reveal drug and alcohol presence over a detection span of up to three months. It is straightforward to collect, challenging to tamper with, and facile to transport.
A 1.5-inch segment consisting of about 200 hair strands (approximately the diameter of a #2 pencil) closest to the scalp yields 100mg of hair, representing the optimal quantity for screening and confirmation. For EtG, additional tests, or assessments beyond 10 panels, 150mg of hair is advised. We suggest measuring the sample on a jeweler’s scale. Should scalp hair be unattainable, a comparable quantity of body hair can be collected. When mentioning head hair, we specifically mean scalp hair. Body hair includes all other varieties (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result includes the four key steps of Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the initial processing of a sample into a lab’s system is conducted. This step involves confirming the sample was properly sealed and delivered, allocating a random LAN (Laboratory Accessioning Number), and completing any further data input not supplied by an electronic chain of custody system.
Screening involves a preliminary rapid inspection for abused drugs. While it’s a cost-effective approach to eliminate drug usage for most samples, a positive screen must be corroborated to be legally valid. Any samples that yield a presumable positive in the Screening phase need confirmation via a secondary test.
If Screening indicates a presumable positive result, additional hair is extracted from the initial collection and prepped for Extraction. Drugs are pulled from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.
Confirmation of any positive Screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. From Accessioning to Confirmation, the entire lab process is reviewed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
