Hair analysis is now recognized as an effective method for identifying substance and alcohol use. Hair captures a comprehensive history of alcohol and other substances by embedding indicators within the fibers of the hair as it grows. When collected from near the scalp, hair can offer nearly a 90-day detection period for alcohol and various substances. It is straightforward to collect, less prone to tampering, and easy to send.
A sample measuring 1.5 inches and comprising roughly 200 hair strands (about the width of a #2 pencil) cut close to the scalp will yield 100mg of hair, which is the optimal amount for both screening and verification. For EtG, additional checks, and/or analyses exceeding 10 panels, a specimen of 150mg is advised. It is suggested to measure the specimen using a jeweler’s scale. If scalp hair is missing, an equivalent quantity of body hair may be used. When we mention head hair, we mean scalp hair exclusively. Body hair encompasses all other varieties (such as facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test result involves four critical steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary handling of a sample into the lab's system. This step includes confirming the sample is sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and finalizing any extra data input not covered by an electronic chain of custody protocol.
Screening provides a preliminary rapid assessment for substances of abuse. Although Screening is an economical approach for eliminating drug use in most samples, a positive screen needs validation for court acceptance. Any sample appearing positive in Screening requires additional confirmation.
If a sample tests presumptively positive during Screening, extra hair is taken from the original specimen and readied for Extraction. In this phase, substances are extracted from hair at much lower concentrations compared to other methods (such as urine or saliva), which is why hair drug testing is the most complex method to perform.
Confirmation for any positive Screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to verification as necessary. The whole laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the certification to ISO / IEC 17025 criteria.
