Hair testing is recognized as an effective method for identifying drug and alcohol usage. Hair holds a comprehensive record of alcohol and drug use by embedding biomarkers within the strands. When collected near the scalp, it offers approximately a three-month detection period for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and convenient for transportation.
A sample measuring 1.5 inches and comprising roughly 200 hair strands (equivalent to the thickness of a #2 pencil) close to the scalp yields about 100mg, which is ideal for both screening and confirmation. For EtG enhancements or tests exceeding 10 panels, a sample weighing 150mg is suggested. It's recommended to use a jeweler’s scale to weigh the sample. If scalp hair isn’t available, an equivalent amount of body hair can be used. Head hair specifically refers to scalp hair, while body hair includes all other hair types (such as facial or axillary).
Process Overview
The key stages in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with the introduction of a sample into a lab system. This process includes ensuring the sample was properly sealed and delivered, assigning a LAN (Laboratory Accessioning Number), and finishing any additional data entry required beyond the electronic chain of custody system.
Screening provides a preliminary assessment for drug traces. Although cost-effective for ruling out drug use in most samples, a positive screen must be verified for legal acceptability. Samples testing presumptively positive in Screening undergo further confirmation.
Upon receiving a presumptive positive result in Screening, additional hair is taken from the original sample for Extraction. Here, drugs are isolated from hair at much lower concentrations than seen in methodologies like urine or oral fluid screening, marking hair drug tests as particularly challenging.
Confirmation of any preliminary positive is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Samples testing presumptive positive are washed before confirmation if needed. The complete lab procedure from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 standards.
