Hair analysis is now recognized as an effective means for identifying drug and alcohol consumption. Hair retains a long-term record of drugs and alcohol by capturing biomarkers within the growing hair fiber. When hair is taken near the scalp, it can offer nearly a 3-month timeframe for detecting alcohol and drugs. Hair is straightforward to collect, relatively hard to tamper with, and convenient to transport.
A 1.5-inch section of roughly 200 hair strands (approximately the breadth of a #2 pencil) nearest to the scalp will provide 100mg of hair, the optimal sample for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advised. It's suggested to weigh the sample using a jeweler’s scale. If scalp hair isn't available, an equivalent amount of body hair can be collected. When referring to head hair, we strictly mean scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The primary steps in the lab analysis of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary handling of a sample into a laboratory’s workflow. This process checks that the sample was correctly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and performs any extra data entry not provided by an electronic chain of custody system.
Screening is a preliminary rapid assessment for drugs of abuse. While Screening is a cost-efficient method to exclude drug use in the majority of samples, for court admissibility, a positive screen requires confirmation. Any sample that is presumptively positive in Screening necessitates an additional confirmation.
In the event a sample is presumptively positive in the Screening phase, additional hair from the initial sample is prepared for Extraction. This phase extracts drugs from hair at much lower levels than other methods (e.g., urine or oral fluid), making hair drug analysis one of the most complex methods to execute.
Positive screening results are verified through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if needed. The entire lab procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.
