Hair testing is recognized as an effective approach for detecting drug and alcohol consumption. Hair captures a detailed record of alcohol and other drugs by trapping indicators within the fibers of its growing strands. When hair is taken near the scalp, it can reveal substance use for up to about a 3-month period in terms of alcohol and other drugs. Collection of hair is straightforward, tampering is somewhat challenging, and shipping is convenient.
A 1.5-inch segment composed of roughly 200 hair strands, comparable to a #2 pencil's size, taken closest to the scalp, yields 100mg of hair, which is the recommended quantity for both screening and confirmation. For EtG, supplementary tests, or evaluations beyond 10 panels, 150mg of the sample is advisable. It's suggested to measure the hair specimen using a jeweler’s scale. If scalp hair is unavailable, a comparable amount of body hair may be used. The reference to head hair specifically means scalp hair only. Body hair indicates all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary handling of a sample within a laboratory’s system. This process confirms that the sample was appropriately sealed and sent, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any extra data entry not supplied by an electronic chain of custody system.
Screening involves a quick preliminary assessment for drugs of abuse. While Screening is a cost-efficient method to rule out drug use in the bulk of samples, any positive indication requires confirmation to be valid in court. Samples that present positive in Screening need a further verification step.
Should a sample test positive in the Screening phase, additional hair is collected from the initial sample for the Extraction process. During this stage, drugs are withdrawn from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening a complex technique.
Confirmation of any positive screening result employs GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples receive a washing before Confirmation as necessary. The entire lab process from Accessioning to Confirmation follows the guidelines of the CAP (College of American Pathologists) Hair designation and meets the ISO / IEC 17025 standards for accreditation.
