Hair testing is recognized as an effective means to identify the consumption of drugs and alcohol. Hair serves as a repository for a prolonged history of these substances by capturing biomarkers within the strands as the hair grows. When clipped close to the scalp, hair can yield a detection span of approximately three months for alcohol and various drugs. It is easy to acquire, challenging to tamper with, and straightforward to transport.
A 1.5-inch segment of roughly 200 hairs (comparable in diameter to a #2 pencil) nearest to the scalp provides 100mg of hair, which is the ideal quantity for both screening and confirmation. For EtG, additional tests, and assessments exceeding 10 panels, 150mg of the sample is advised. We suggest measuring the specimen using a jeweler’s scale. Should scalp hair be unavailable, an equivalent amount of body hair can be taken. When we mention head hair, we specifically mean scalp hair, while body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The key phases in lab processing of drug test outcomes are Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial handling of a sample within a lab’s framework. This step ensures the sample was correctly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and finalizes any extra data entry absent in an electronic chain of custody system.
Screening entails a preliminary rapid assessment for drugs of abuse. Though Screening is a cost-efficient method to eliminate drug presence in most specimens, a positive screen necessitates confirmation for court admissibility. Samples indicating a presumptive positive in Screening must undergo secondary verification.
If the Screening phase indicates a presumptive positive, additional hair is fetched from the original sample for Extraction. In this phase, drug compounds are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), which underscores the complexity of hair drug testing procedures.
Positive results from screening are validated through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if deemed necessary. The complete lab process from Accessioning to Confirmation undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and the conformance to ISO / IEC 17025 standards.
