Hair testing is increasingly regarded as a robust method for identifying drug and alcohol consumption. Hair strands offer a prolonged timeline of alcohol and drug use by capturing biomarkers within the fibers of the growing hair. When collected near the scalp, hair can yield up to a 3-month detection window for alcohol and drugs. It is easy to collect, relatively hard to tamper with, and straightforward to transport.
A sample measuring 1.5 inches and consisting of roughly 200 hair strands (comparable to a #2 pencil in size) nearest to the scalp provides 100mg of hair, which is the perfect sample size for analysis. For EtG add-ons and/or tests exceeding 10 panels, 150mg of the specimen is suggested. It's best to measure the specimen with a jeweler’s scale. If scalp hair is not available, a similar quantity of body hair can be used. References to head hair mean scalp hair only, while body hair refers to other hair types (like facial or axillary).
Process Overview
The key steps in processing a drug test in the lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves initially processing a sample into the lab’s system. This process confirms that the sample was sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry not covered by an e-chain of custody system.
Screening is a swift preliminary check for drug abuse. Although Screening is a cost-efficient approach to dismiss drug use in the majority of samples, a positive result necessitates confirmation for legal admissibility. Any samples with presumptive positives in Screening must undergo secondary confirmation.
If a sample shows a presumptive positive in Screening, additional hair is taken from the initial specimen for Extraction. This phase involves extracting drugs from hair at a significantly lower concentration than in other methodologies (like urine or oral fluid), making hair drug screening the most challenging to execute.
Confirming any positive Screening outcome is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation if needed. The full lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and accredited to ISO/IEC 17025 standards.
