Hair testing has emerged as an effective method for identifying the presence of drugs and alcohol. Hair offers an extensive timeline of drug and alcohol use by capturing biomarkers within the strands of hair as they grow. When gathered near the scalp, hair can reveal drug and alcohol use history over a period of up to three months. It is straightforward to collect, relatively resistant to tampering, and convenient to transport.
A sample measuring 1.5 inches, roughly comprising 200 hair strands (similar in width to a #2 pencil) nearest the scalp, provides 100mg of hair, which is ideal for both preliminary and confirmatory testing. For EtG, additional tests, and panels exceeding 10, 150mg is suggested. Using a jeweler’s scale to weigh the specimen is advisable. If scalp hair isn't available, an equivalent amount of body hair can be obtained. By head hair, we mean scalp hair exclusively. Body hair encompasses other hair types (facial, axillary, etc.).
Process Overview
The key phases in processing a drug test result in a laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial handling of a sample within a laboratory's system. This includes ensuring that the sample is sealed and transported correctly, assigning a unique Laboratory Accessioning Number (LAN), and completing any extra data entry absent from an electronic chain of custody system.
Screening entails a preliminary assessment for drugs of abuse. While cost-effective, Screening requires a subsequent confirmation to validate any positive findings for legal proceedings. Samples showing presumptive positive results in Screening necessitate further confirmation.
When a sample shows a presumptive positive in the Screening stage, additional hair is taken from the initial sample for the Extraction process. During this phase, drugs are extracted from the hair at much lower concentrations than in methodologies like urine or oral fluid tests, making hair drug screening a challenging method to perform.
Positive results from Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed as required before Confirmation. The comprehensive process from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair designation and accreditation according to ISO / IEC 17025 standards.
