Hair testing is widely acknowledged as an effective means for identifying drug and alcohol consumption. Hair offers a long-range overview of alcohol and drug intake by preserving biomarkers within the fibers of the developing hair strand. When gathered close to the scalp, hair can yield a detection window of up to about 3 months for alcohol and other drugs. Hair collection is straightforward, relatively tamper-proof, and convenient to transport.
A 1.5-inch segment of roughly 200 hair strands (similar in diameter to a #2 pencil) nearest the scalp delivers 100mg of hair, the optimal quantity for evaluation and validation. For EtG, additional tests, and/or panels exceeding 10, 150mg of the sample is suggested. Using a jeweler’s scale to weigh the specimen is recommended. If scalp hair is unavailable, a comparable quantity of body hair may be harvested. When discussing head hair, we mean scalp hair alone. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The four central stages in the laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into a laboratory’s framework. This process includes confirming proper sealing and shipment of the sample, generating a random LAN (Laboratory Accessioning Number), and performing any supplementary data entry not fulfilled by an electronic chain of custody system.
Screening comprises an initial rapid evaluation for substance abuse. Though Screening is a budget-friendly approach to dismiss drug use on most samples, a positive result requires validation for legal admissibility. All samples with presumptive positives in Screening necessitate additional confirmation.
If a sample shows a presumptive positive result at the Screening phase, further hair is taken from the initial sample and readied for Extraction. During this phase, drugs are isolated from hair at significantly lower concentrations than in other methodologies (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.
Positive screening results undergo Confirmation utilizing GC/MS, GC/MS/MS, or LC/MS/MS methods. Every presumptive positive sample is washed before confirmation if warranted. The complete lab procedure from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 requirements.
