Hair analysis is increasingly recognized as an effective means for detecting drug and alcohol consumption. By embedding biomarkers within the strands of growing hair, it offers a comprehensive timeline of substance usage. When gathered near the scalp, hair can present a detection window extending up to three months for alcohol and drugs. The collection process is straightforward, the risk of tampering is relatively low, and the specimen is easy to transport.
A sample measuring 1.5 inches, containing roughly 200 hair strands (equivalent to the thickness of a #2 pencil), gathered closest to the scalp, will yield 100mg of hair—ideal for both initial screening and confirmation testing. For EtG, additional check-ups, or beyond 10-panel tests, a 150mg sample is suggested. It’s advisable to use a jeweler’s scale for specimen measurement. In the absence of scalp hair, an equivalent quantity of body hair can be collected. The term "head hair" is specific to scalp hair, while "body hair" encompasses all other types (like facial and underarm hair).
Process Overview
The core stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial intake of a specimen into a lab’s workflow. This phase involves ensuring that the sample is properly sealed and dispatched, randomly generating a LAN (Laboratory Accessioning Number), and completing any data input not handled by an electronic chain of custody system.
Screening functions as a preliminary rapid assessment for substance use. Despite its cost-effectiveness in negating drug use across most samples, a positive result necessitates confirmation to be usable in legal settings. Samples indicating a presumptive positive outcome in Screening demand further confirmation.
Upon obtaining a presumptive positive in Screening, additional hair is extracted from the original sample for the Extraction phase. This process isolates drugs from hair at notably lower concentrations than other methods (such as urine or oral fluid), contributing to the complexity of hair drug screening as a methodology.
To confirm any positive screening outcome, methods such as GC/MS, GC/MS/MS, or LC/MS/MS are utilized. All samples deemed presumptively positive undergo a washing process before confirmation as required. The entire laboratory procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although commonly termed "hair follicle tests", the analysis is conducted on the hair strand, not the root beneath the scalp.
Why Hair Follicle Testing Outshines Urine Testing in Herendeen Bay, AK
