Hair testing has emerged as an effective method for identifying drug and alcohol consumption. The hair captures long-term evidence of alcohol and drug presence by embedding biomarkers in its strands as they grow. Hair collected near the scalp offers a detection span of up to three months for substances like alcohol and drugs. Hair sampling is straightforward, relatively resistent to tampering, and simple to transport.
A cut of 1.5 inches consisting of about 200 hair strands (comparable to the width of a #2 pencil) closest to the scalp yields 100mg of hair, optimal for analysis and verification. For EtG, additional testing, or more than 10 panel tests, 150mg of hair is suggested. It's advisable to use a jeweler’s scale for accurate weighing of the sample. If scalp hair isn't accessible, a similar quantity of body hair can be collected. When mentioning head hair, we mean scalp hair exclusively, while body hair encompasses all other hair forms (such as facial, axillary, etc.).
Process Overview
The laboratory drug test procedure is comprised of four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial handling of a sample within a laboratory’s system. This step ensures the sample's proper sealing and transit, assigns a unique LAN (Laboratory Accessioning Number), and concludes any supplementary data recording absent in an electronic chain of custody system.
Screening necessitates a preliminary rapid examination for drug abuse. While cost-efficient for excluding drug usage in most cases, a positive Screening result requires confirmation for court admissibility. Any presumptive positive findings in Screening necessitate a subsequent verification.
If Screening results in a presumptive positive, additional hair is extracted from the original sample and readied for Extraction. In this stage, drugs are removed from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), which makes hair drug screening a particularly challenging methodology.
Verification of any positive screen result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumed positive samples receive a wash before final confirmation if needed. The complete laboratory process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.
