Hair testing has increasingly been regarded as an impactful means for detecting drug and alcohol consumption. The hair captures a prolonged historical record of drugs and alcohol by embedding biomarkers within its fiber as it grows. When collected near the scalp, a hair sample can offer approximately a 3-month timeframe to detect drugs and alcohol. The collection process for hair is straightforward, somewhat resistant to tampering, and easy to transport.
A hair sample of 1.5 inches comprising around 200 strands (equivalent to a #2 pencil) near the scalp provides 100mg of hair, an optimal measure for screening and confirmation. For tests including EtG, additional panels beyond 10 require 150mg of the specimen. We suggest using a jeweler’s scale to weigh the specimen. In absence of scalp hair, an equivalent volume of body hair can be procured. References to head hair denote scalp hair specifically. All other hair types (facial, axillary, etc.) are categorized as body hair.
Process Overview
The procedure for laboratory processing of drug test results includes four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails introducing a sample into the laboratory system. This process involves checking that the sample was appropriately sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and finalizing any further data entry absent from the electronic chain of custody system.
Screening entails an initial, rapid assessment for drugs of abuse. While Screening is a cost-effective method for eliminating drug use in most samples, confirmatory testing is essential for any samples that screen positively, especially for legal acceptability. Positive Screening results necessitate a further confirmation step.
Should a sample show a presumptive positive at the Screening phase, additional hair is extracted from the original specimen and processed for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations compared to other methods (such as urine or oral fluids), which adds complexity to hair drug screening.
Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Samples flagged as presumptive positives undergo washing before confirmation, if necessary. The progression from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
