Hair testing is now regarded as a potent approach for recognizing drug and alcohol consumption. Hair retains a long-term record of alcohol and other substances by embedding biomarkers within the fibers of the growing hair. Gathering hair close to the scalp offers nearly a 3-month timeframe for drug and alcohol detection. Hair is easy to collect, relatively challenging to tamper with, and straightforward to transport.
A 1.5-inch strand sample containing about 200 hairs (around the dimension of a #2 pencil) nearest the scalp yields 100mg of hair, which is the perfect sample size for both screening and confirmation. For EtG, additional tests, or assessments beyond 10 panels, a 150mg specimen is advised. It's recommended to weigh the sample using a jeweler’s scale. If hair on the scalp isn't present, a corresponding amount of body hair can be gathered. When discussing head hair, it refers solely to scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The four core phases in the lab handling of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial entering of a sample into a lab’s system. This entails ensuring the sample was sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and finishing any extra data entry not offered by an electronic chain of custody system.
Screening comprises an initial brief inspection for drugs of abuse. Although Screening is a cost-efficient method to exclude drug consumption in most samples, a positive screen requires confirmation to be valid in court. Any samples that test presumptively positive in Screening necessitate secondary confirmation.
When a sample tests presumptively positive during the Screening phase, more hair is extracted from the initial sample and readied for Extraction. Here, drugs are withdrawn from hair at lower concentrations than in other techniques (e.g., urine or oral fluid), making hair drug screening a challenging procedure to execute.
Confirmation of any positive screening result is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation if necessary. The comprehensive laboratory process from Accessioning to Confirmation is reassessed under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.
