Hair testing is increasingly acknowledged as a significant method for identifying substance use. Hair offers a historical overview of substance consumption by capturing biomarkers within the strands as they develop. When gathered near the scalp, hair can reveal drug and alcohol use over about a three-month span. Hair collection is straightforward, hard to tamper with, and easy to transport.
A 1.5-inch segment consisting of roughly 200 hair strands (comparable to a #2 pencil) near the scalp provides 100mg, the optimal amount for tests. For EtG, additional tests, or screenings over 10 panels, 150mg is advised. Using a jeweler’s scale to weigh the sample is advised. If scalp hair is not available, an equivalent volume of body hair can be taken. Head hair refers specifically to scalp hair, whereas body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The primary stages in the laboratory analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a specimen within a lab's system. This involves confirming the sample’s proper sealing and shipping, generating a unique LAN (Laboratory Accessioning Number), and concluding any incomplete data due to the absence of an electronic chain of custody system.
Screening is a preliminary test for substances of abuse. While cost-efficient for ruling out drug use in most samples, a positive screen necessitates confirmation to be valid in legal contexts. Samples indicating positive in Screening must proceed to a secondary confirmation.
Should a sample present a presumptively positive result during Screening, additional hair is utilized from the original sample for Extraction. This stage isolates substances from hair at much lower concentrations than alternative methods (e.g., urine or oral fluid), underscoring the complexity of hair drug screening.
Any positive screening is confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation when necessary. The entire laboratory workflow from Accessioning through Confirmation is scrutinized according to the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
