Hair analysis has emerged as an effective technique for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug use by embedding biomarkers within the fibers of the developing hair. When obtained near the scalp, hair can reveal a detection timeframe of up to three months for alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and simple to transport.
A sample of 1.5 inches consisting of approximately 200 hair strands (equivalent to the diameter of a #2 pencil) near the scalp yields 100mg of hair, which is the ideal quantity for screening and verification. For EtG, additional procedures, and/or assessments exceeding 10 panels, 150mg of the sample is advised. It is suggested to measure the sample with a jeweler’s scale. If scalp hair is not obtainable, an equivalent amount of body hair may be gathered. When talking about head hair, it specifically refers to scalp hair. Body hair includes all other hair types (including facial, axillary, etc.).
Process Overview
The key stages in a laboratory's drug test processing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a specimen into the laboratory’s records. This process ensures the sample was sealed and transported adequately, assigns a random LAN (Laboratory Accessioning Number), and handles any extra data entry not covered by the electronic custody chain system.
Screening executes an initial brief evaluation for drug abuse. Although Screening is a cost-efficient method to dismiss drug usage on the bulk of samples, a positive outcome requires confirmation for legal acceptance. Any specimens that yield a presumptive positive in Screening necessitate further confirmation.
If a specimen is reportedly positive in the Screening stage, a larger portion of hair is extracted from the original sample and readied for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations than other methods (like urine or saliva), which explains why hair drug analysis is the most challenging procedure to conduct.
Confirmation for any positive Screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation when required. The complete laboratory procedure from Accessioning to Confirmation is monitored under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although frequently termed "hair follicle tests", the examination itself focuses on the hair strand, not the follicle beneath the scalp.
