Hair analysis has emerged as a significant method for detecting drug and alcohol consumption. Hair captures markers of alcohol and drugs within the strands as it grows, providing a timeline of use. Gathering hair close to the scalp can reveal substance use for approximately a 3-month period. Collecting hair is straightforward, with minimal risk of tampering, and is conveniently transportable.
Securing a 1.5-inch section of around 200 hairs (akin to a #2 pencil's circumference) near the scalp delivers 100mg of hair, the perfect quantity for initial screening and further verification. For EtG assessments, additional panels, or tests exceeding 10 panels, a 150mg sample is ideal. We advise using a jeweler's scale to weigh the hair. Should scalp hair not be available, a similar volume of body hair can suffice. "Head hair" denotes only scalp hair, while "body hair" includes all other hair types (facial, armpit, etc.).
Process Overview
There are four key stages in the laboratory evaluation of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning incorporates the sample into the laboratory's database. This step confirms proper sealing and shipping of the sample, assigns an arbitrary LAN (Laboratory Accessioning Number), and records any extra details absent from an electronic chain of custody.
Screening performs an initial assessment for drug presence. While Screening efficiently rules out drug use for most samples, further confirmation is necessary for legal acceptance of a positive result. Samples testing presumptively positive in Screening require additional confirmation.
For samples presumptively positive during Screening, further hair extraction from the initial collection occurs for the Extraction phase. Here, drug concentration in hair is notably lower than in urine or oral samples, making hair drug testing one of the most complex methodologies.
Confirmation of any positive result is achieved through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, presumptive positive samples undergo washing if needed. From Accessioning to Confirmation, the entire process adheres to CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
