Hair analyses have emerged as an effective method for detecting drug and alcohol consumption. Hair captures a chronological record of alcohol and other substances by retaining biomarkers within the strands. When clipped near the scalp, hair offers up to about a 3-month timeframe for identifying alcohol and drugs. Hair is easy to obtain, relatively hard to tamper with, and convenient for transport.
A 1.5-inch snippet containing roughly 200 hairs (similar in size to a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal amount for analysis. For EtG, additional measures, and/or evaluations exceeding 10 panels, 150mg of the sample is advisable. It's suggested to use a jeweler’s scale for specimen measurement. If head hair isn't accessible, an equivalent quantity of body hair can be used. Here, head hair signifies scalp hair specifically. Body hair encompasses all other hair forms (like facial, axillary, etc.).
Process Overview
The primary stages in lab processing of a drug analysis result comprise Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial inclusion of a sample into a lab’s framework. This step involves confirming the sample's proper sealing and transport, allocating a unique LAN (Laboratory Accessioning Number), and finishing any extra data tasks not covered by an electronic custody chain system.
Screening includes an initial rapid assessment for substances. While Screening is an economical solution to disqualify drug presence in most samples, a positive result necessitates confirmation to be valid in legal contexts. Samples that test presumptively positive in Screening do require an additional verification.
If Screening indicates a presumptive positive, more hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are drawn from hair at a significantly lower level than in alternative methods (like urine or oral samples), making hair drug testing a challenging methodology to execute.
Any positive Screening outcomes undergo Confirmation via GC/MS, GC/MS/MS or LC/MS/MS. All presumptively positive samples are cleansed before confirmation if needed. The complete lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.
