Hair evaluation is increasingly recognized as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged history of substance use by integrating biomarkers within the fibers of growing hair. When acquired near the scalp, it can reflect a detection timeline of up to around three months for substances like alcohol and drugs. Collecting hair is straightforward, resistant to tampering, and convenient to transport.
A sample of 1.5 inches comprising around 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp yields 100mg, optimal for both screening and confirmation. For EtG, extra tests, and/or panels exceeding 10, a sample of 150mg is advised. Using a jeweler’s scale to weigh the sample is suggested. If scalp hair is unavailable, a similar quantity of body hair may be gathered. When discussing head hair, we refer solely to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary processing of a sample into the lab’s system. This stage confirms the sample's proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data shortcomings not provided via an electronic chain of custody system.
Screening is a preliminary cursory examination for substances of abuse. Although Screening offers a cost-efficient method to negate drug use across most samples, court-admissible results require confirmatory testing. Samples that yield a presumptive positive during Screening necessitate further confirmation.
For samples with presumptive positive results in Screening, additional hair is extracted from the initial sample for the Extraction phase. During this stage, drug substances are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring the complexity of performing hair drug screening.
Confirmation of any positive Screening outcome is enacted using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing before confirmation, as needed. The comprehensive lab process that includes Accessioning to Confirmation is subject to review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
