Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. Hair can offer an extended record of alcohol and other substances by capturing biomarkers within the strands of the growing hair. When taken near the scalp, hair offers approximately a 3-month detection timeframe for alcohol and substances. Hair is easy to collect, quite resistant to tampering, and straightforward to transport.
A 1.5-inch length of roughly 200 hair strands (around the thickness of a #2 pencil) closest to the scalp provides 100mg of hair, which is the optimal sample size for screening and validation. For EtG, additional tests, and/or those beyond 10 panels, a specimen size of 150mg is advisable. We suggest measuring the specimen with a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair may be used. References to head hair relate exclusively to scalp hair. Body hair encompasses all other hair forms (facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test result comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary handling of a sample within a laboratory’s framework. This incorporates confirming the sample was appropriately sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data input absent from an electronic chain of custody system.
Screening encompasses an initial rapid evaluation for substance abuse. While Screening is a budget-friendly method to exclude drug usage in the majority of samples, any positive screen needs confirmation to be valid in legal settings. Any samples appearing presumptively positive during Screening require a follow-up confirmation.
Should a sample yield a presumptively positive result during the Screening phase, additional hair is separated from the original specimen and readied for Extraction. During this phase, substances are isolated from hair at a notably lower concentration than through other methodologies (e.g., urine or oral fluid), which is why hair drug testing presents the most challenging methodology to perform.
The verification of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation, as required. The entire lab process, from Accessioning to Confirmation, is thoroughly reviewed under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.
