Hair testing is increasingly recognized as a robust method for detecting drug and alcohol consumption. Hair offers a prolonged overview of substance use by encasing biomarkers in the strands of growing hair. When collected near the scalp, hair can supply a detection period of up to about 3 months for alcohol and other substances. Hair is easy to gather, not easily altered, and convenient to ship.
A 1.5-inch sample of roughly 200 hair strands (akin to a #2 pencil in thickness) nearest to the scalp yields 100mg of hair, which is the optimal quantity for screening and confirmation. For EtG, additional tests, and/or tests beyond 10 panels, 150mg of the sample is advisable. It is recommended to weigh the sample with a jeweler's scale. If scalp hair cannot be sourced, an equivalent amount of body hair may be collected. When mentioning head hair, it specifically refers to scalp hair. Body hair refers to all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test outcome comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning incorporates the preliminary processing of a sample into a lab's system. This entails verifying that the sample was properly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and completing any extra data entry not supplied by an electronic chain of custody system.
Screening involves an initial rapid assessment for substances of abuse. While Screening is a cost-efficient means to dismiss drug usage on most samples, a positive result must be confirmed to be permissible in legal proceedings. Samples that are initially positive in Screening require follow-up confirmation.
If a sample is initially positive in the Screening phase, additional hair is drawn from the original sample and readied for Extraction. In this phase, drugs are drawn from hair at significantly lower concentrations than other approaches (e.g., urine or oral fluid), underscoring why hair drug screening is the most challenging methodology to undertake.
Confirmation of any positive screening outcome is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is inspected under the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.
