Utilizing hair testing has emerged as a significant method for identifying the consumption of drugs and alcohol. Hair acts as an historical record of alcohol and drug usage by encasing biomarkers within the strands as they grow. When sampled near the scalp, hair can offer a detection timeframe of up to three months for alcohol and various drugs. It is straightforward to collect, relatively resistant to tampering, and simple to transport.
A hair sample measuring 1.5 inches and comprising roughly 200 strands (about the thickness of a #2 pencil) nearest to the scalp will provide 100mg of hair, which is ideal for testing and verification. For EtG, additional tests, and/or those spanning more than 10 panels, 150mg of hair is advised. Using a jeweler’s scale is recommended for weighing the specimen. In instances where scalp hair is absent, the equivalent quantity of body hair can be used. When discussing head hair, we mean scalp hair solely. Body hair refers to all other types of hair (e.g., facial, axillary).
Process Overview
The method of assessing a drug test result in the lab involves four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase, encompassing entering a sample into the laboratory's records. This process checks that the sample was sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and concludes any other data entry not captured by an electronic custody chain system.
Screening entails an initial rapid examination for drug abuse. Although Screening is a budget-friendly approach to dismiss drug use in most samples, testing positive necessitates confirmation for legal admissibility. Any samples showing presumptive positive results during Screening must undergo a confirmatory test.
In cases where a sample tests presumptive positive during the Screening phase, additional hair is extracted from the initial sample in preparation for Extraction. During this process, drugs are derived from the hair at much more diluted concentrations than other methods (e.g., urine or oral fluid), making hair drug testing one of the most challenging techniques to execute.
Confirmation of any positive results from the screening phase is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptively positive are cleansed prior to confirmation where needed. The entire lab procedure from Accessioning through Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.
