Viewed as a strong instrument, hair testing effectively identifies alcohol and drug usage. Hair records a prolonged history of these substances by embedding biomarkers into the hair strand's fibers as it grows. When sampled close to the scalp, hair can offer a detection range of up to around three months for alcohol and drugs. Hair is easy to collect, somewhat hard to tamper with, and simple to transport.
A 1.5-inch piece comprising approximately 200 hair strands (about the diameter of a #2 pencil) nearest to the scalp delivers 100mg of hair, which is the preferred specimen size for both screening and confirmation. For EtG, add-ons, or panels exceeding 10 tests, a specimen of 150mg is advised. It is suggested to weigh the sample using a jeweler's scale. Should scalp hair be inaccessible, the equivalent volume of body hair can be gathered. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test is composed of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers incorporating a sample into a lab's system. This step involves confirming the sample’s proper sealing and shipment, generating a random LAN (Laboratory Accessioning Number), and completing any leftover data entry not handled by an electronic chain of custody framework.
Screening provides an initial rapid evaluation for potential drug abuse. While this step offers a cost-efficient means to dismiss drug use in the majority of cases, a positive screen necessitates confirmation to be legally admissible. Samples yielding a presumptive positive in Screening need secondary confirmation.
For samples testing presumptively positive at the Screening phase, additional hair is extracted from the original specimen for preparation during the Extraction phase. During this step, substances are isolated from hair at much lower concentrations compared to other methods (ex. urine or oral fluid); hence, hair drug testing stands as the most complex method to conduct.
Confirmation for any positive screening outcome occurs through GC/MS, GC/MS/MS, or LC/MS/MS. If required, all presumptive positive specimens are washed prior to confirmation. The comprehensive lab process from Accessioning through Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and accreditation adhering to ISO/IEC 17025 standards.
