Hair tests are increasingly recognized as an effective means for identifying drug and alcohol consumption. As hair grows, it embeds biomarkers within its fiber, offering a comprehensive timeline of alcohol and drug exposure. When taken near the scalp, hair samples provide a detection period of up to around three months for alcohol and drugs. Sample collection is straightforward, the risk of tampering is low, and samples are easy to transport.
A sample size of 1.5 inches, comprising roughly 200 hair strands (about the thickness of a #2 pencil) and taken nearest the scalp, yields 100mg of hair, which is optimal for testing and validation. For EtG, additional tests, or those exceeding 10 panels, a specimen weighing 150mg is suggested. A jeweler’s scale is recommended for precise measurement. In cases where scalp hair isn’t available, an equivalent amount of body hair can be collected. The term "head hair" specifies only scalp hair, whereas "body hair" includes all other hair types (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial integration of a sample into a lab's system. This stage includes verifying the sample’s seal and proper shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any remaining data entry not handled by an electronic chain of custody system.
Screening is the preliminary evaluation for substance abuse. Although Screening provides an economical way to discard drug usage in most samples, any positive results must be verified for court admissibility. Samples that test positive at this stage necessitate a further confirmation.
For samples indicated as positive during Screening, additional hair is acquired from the initial sample and prepped for Extraction. This phase extracts drugs from hair in significantly lower concentrations than other methods (such as urine or oral fluid), making hair drug screening a complex methodology.
The Confirmation of positive screenings is executed using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are cleansed as necessary. From Accessioning through Confirmation, the entire lab process is assessed according to both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
