Hair examinations have emerged as a significant approach for identifying substance use. Hair records a prolonged timeline of alcohol and drug intake by embedding biomarkers within its fibers as it grows. When gathered near the scalp, it offers approximately a three-month detection period for alcohol and drugs. Collecting hair is straightforward, less prone to tampering, and easy to transport.
A 1.5-inch segment consisting of around 200 hair strands (comparable in size to a #2 pencil) close to the scalp yields 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, and/or those surpassing 10 panels, it’s suggested to use 150mg of the sample. It's advisable to weigh the hair sample using a jeweler’s scale. If scalp hair is not an option, an equivalent quantity of body hair can be used. When the term head hair is used, it specifically indicates scalp hair. Body hair pertains to other varieties (facial, underarm, etc.).
Process Overview
There are four crucial stages in processing drug test results in the lab: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, a sample is initially processed into the laboratory's system. This process ensures the sample is properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data input not covered by an electronic chain of custody system.
Screening provides a quick preliminary test for substance abuse. Although Screening is a cost-efficient method to rule out drug use for most samples, following up with confirmation is essential for legal admissibility. Any samples that presumptively test positive during Screening must undergo a secondary confirmation.
Upon a presumptive positive result in Screening, more hair is extracted from the primary sample for the Extraction stage. Here, drugs are extracted from hair at a much lower concentration compared to other methodologies (such as urine or oral fluid), highlighting the complexity of performing hair drug screening.
GC/MS, GC/MS/MS, or LC/MS/MS methods handle the Confirmation of any positive screening outcomes. Prior to confirmation, any samples with presumptive positive results are washed as necessary. The entire process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair standards and accredited to ISO / IEC 17025 standards.

Note: The term "hair follicle tests" is often used, but the analysis is conducted on the hair strand rather than the follicle beneath the scalp.
