Hair analysis is now recognized as an effective approach for identifying the use of substances like drugs and alcohol. Hair retains a comprehensive record of substance use by embedding biomarkers within the growing hair strand fibers. When sampled near the scalp, it can reveal substance usage for up to around three months. The collection of hair is straightforward, not easily altered, and conveniently shipped.
A typical sample of 1.5 inches, roughly 200 hair strands (similar in thickness to a #2 pencil) closest to the scalp, yields 100mg of hair, which is ideal for both screening and confirmation purposes. For tests involving EtG, additional tests, or those exceeding 10 panels, a 150mg sample is suggested. It’s advisable to use a jeweler’s scale to measure the specimen weight. If scalp hair is unavailable, a comparable quantity of body hair can be used. When head hair is mentioned, it specifically refers to scalp hair. Body hair encompasses other hair types such as facial or axillary hair.
Process Overview
The primary phases in the lab analysis of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning signifies the first step where a sample gets processed into the lab system. This stage includes checking the proper sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry omitted by an electronic chain of custody system.
Screening entails a preliminary inspection for drug abuse. Screening is cost-efficient for eliminating drug use for most samples, yet a positive result requires confirmation to be valid in court. Samples that show a presumptive positive in Screening need secondary confirmation.
In the event of a presumptive positive result at the Screening phase, additional hair is taken from the initial sample and prepped for Extraction. Drugs are then extracted from hair at significantly lower concentrations than in other methods (for instance, urine or oral fluid), which makes hair drug screening a challenging methodology.
Confirmation of any presumptive positive result from Screening is achieved using GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positive samples undergo washing before confirmation if required. From Accessioning through Confirmation, the whole lab procedure is subject to review under both the CAP (College of American Pathologists) Hair standards and the accreditation to ISO / IEC 17025 standards.
