Hair testing is highly regarded as an effective means for identifying substance use involving drugs and alcohol. By encapsulating biomarkers within the fibers of a maturing hair strand, hair offers a prolonged historical record of alcohol and other substances. When cut near the scalp, hair can convey approximately a 90-day detection period for alcohol and drugs. Hair is straightforward to collect, fairly resistant to tampering, and simple to dispatch.
A sample measuring 1.5 inches comprised of around 200 hair strands (roughly matching the size of a #2 pencil) nearest the scalp yields 100mg of hair, which is the optimal amount for both preliminary and confirmatory assessment. For EtG, additional tests, or tests exceeding 10 panels, 150mg of the sample is advised. It is advisable to measure the sample on a jeweler's scale. If scalp hair is not available, an equivalent quantity of body hair can be used. In talking about head hair, it specifically refers to scalp hair. Body hair includes all other kinds of hair (facial, axillary, etc.).
Process Overview
The core steps in lab processing of drug testing are Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial onboarding of a sample into a lab’s system. This step involves ensuring the sample’s seal and proper shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent from an electronic chain of custody system.
Screening acts as a preliminary evaluation for substances of abuse. Although Screening is an economical approach to exclude drug use in most samples, a positive result during this phase requires subsequent confirmation for legal admissibility. Samples that are presumptively positive in Screening need further confirmation.
For samples deemed presumptively positive during the Screening phase, additional hair is extracted from the original specimen and prepped for the Extraction phase. During this step, drugs are withdrawn from hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), highlighting hair drug screening as the most complex methodology.
Confirmation of any presumptively positive screening is performed via GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples undergo washing before confirmation, if needed. The complete laboratory procedure, from Accessioning to Confirmation, adheres to scrutiny under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
