Hair analysis is recognized as a potent instrument for identifying alcohol and drug consumption. Hair retains a prolonged record of alcohol and drug presence by capturing biomarkers within the fibers of the developing hair strand. When gathered near the scalp, hair can offer a detection timeframe of up to around 90 days for alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and easy to transport.
A 1.5-inch segment consisting of about 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal amount for both screening and confirmation. For EtG, additional analyses, and/or tests exceeding 10 panels, a specimen of 150mg is advised. It's recommended to measure the specimen using a jeweler's scale. If scalp hair is not available, a similar amount of body hair may be used. "Head hair" refers exclusively to scalp hair, while "Body hair" encompasses all other types (e.g., facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test involves four essential stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary incorporation of a sample into a lab's system. This process includes confirming that the sample was appropriately sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any additional information entry that isn't covered by an electronic chain of custody system.
Screening involves a preliminary rapid assessment for addictive substances. While Screening is an economical means to eliminate drug usage in most samples, a positive finding needs to be verified to be admissible in legal proceedings. Samples that yield a presumptive positive during Screening require a subsequent confirmation.
If a specimen shows a presumptive positive during Screening, more hair is extracted from the original sample and prepared for Extraction. During this phase, drugs are retrieved from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing a challenging method to execute.
The Confirmation of any positive Screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Any presumptive positive samples undergo washing prior to Confirmation as necessary. The entire lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.
