Hair examinations have emerged as a robust method for identifying alcohol and drug usage. Hair captures a long-term record of these substances by embedding biomarkers within the fibers of the growing hair. When cut near the scalp, hair can offer a detection period of up to roughly three months for alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch segment of roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp will provide 100mg of hair, which is optimal for testing and verifying. For EtG, additional tests, or those exceeding 10 panels, a 150mg sample is advisable. It's suggested to measure the sample using a jeweler's scale. In the absence of scalp hair, a comparable quantity of body hair can be used. When referring to head hair, this specifically indicates scalp hair. Body hair encompasses all other types (e.g., facial, underarm, etc.).
Process Overview
The key stages in the lab analysis of drug test samples are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample into the lab's system. This process verifies that the sample was correctly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data inputs not covered by an electronic custody chain system.
Screening provides a preliminary assessment for drug presence. While it is an economical approach to dismiss drug use for most samples, any positive result from Screening needs confirmation to be valid for court proceedings. Any samples that test as supposed positives in Screening require further confirmation.
If a sample suggests positivity in the Screening phase, additional hair is extracted from the primary sample and readied for Extraction. In this phase, drugs are extracted at much lower concentrations than other techniques (e.g., urine or saliva), which makes hair drug analysis the most complex method to conduct.
GC/MS, GC/MS/MS, or LC/MS/MS methods are used for Confirmation of any positive Screening outcomes. All presumptive positives are thoroughly washed before confirmation if required. The full lab process, from Accessioning to Confirmation, undergoes evaluation under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standards.
