Hair evaluation is now recognized as an influential means for uncovering drug and alcohol consumption. Hair offers a prolonged record of alcohol and other substances by capturing biomarkers within the strands of expanding hair. When gathered near the scalp, hair can indicate up to nearly a 3-month period for detecting alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and convenient for shipping.
A 1.5-inch portion, comprising roughly 200 hair strands (comparable to the size of a #2 pencil) nearest to the scalp, will yield 100mg of hair, which is the optimal quantity for both screening and confirmation. For EtG, additional checks, and/or tests exceeding 10 panels, a 150mg sample is advised. We suggest using a jeweler’s scale for weighing the specimen. If scalp hair is unavailable, an equivalent quantity of body hair may be obtained. When mentioning head hair, we refer exclusively to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory procedures for processing a drug test outcome consist of four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary handling of a sample in the laboratory’s system. This phase ensures the sample was appropriately sealed and dispatched, allocates a random LAN (Laboratory Accessioning Number), and finalizes any supplementary data input absent from an electronic chain of custody system.
Screening constitutes an initial brisk assessment for signs of drug abuse. Though Screening is a budget-friendly method to discount drug consumption in most samples, a positive outcome mandates confirmation for legal reliability. Samples identified as preliminarily positive in Screening must undergo further confirmation.
Should a sample show presumptive positivity during Screening, additional hair is extracted from the original specimen for the Extraction process. In this phase, drugs are isolated from hair at notably lower concentrations than alternative methods (for example, urine or oral fluids), underscoring the complexity of hair drug analysis procedures.
Verification of any positive screening outcome is undertaken via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, presumptive positive samples undergo washing if necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is assessed under the CAP (College of American Pathologists) Hair designation and aligns with the ISO / IEC 17025 accreditation standards.
