Hair testing is recognized as a robust method for identifying drug and alcohol consumption. Hair offers an extended history of drug and alcohol use by embedding biomarkers within the hair fiber as it grows. When collected near the scalp, hair can reveal drug and alcohol usage for up to three months. Hair samples are easy to collect, challenging to tamper with, and straightforward to transport.
A 1.5-inch hair sample consisting of about 200 strands, similar to the width of a #2 pencil, will yield 100mg of hair, the ideal amount for testing and confirmation processes. For EtG, additional tests, or tests exceeding 10 panels, it's recommended to collect 150mg. Using a jeweler’s scale to weigh the sample is advised. If scalp hair is not available, a comparable amount of body hair may be used. 'Head hair' pertains only to scalp hair, while 'body hair' includes all other types (facial, axillary, etc.).
Process Overview
The principal stages in the laboratory handling of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into the laboratory system. This step ensures the sample was properly sealed and shipped, generates a random LAN (Laboratory Accessioning Number), and completes any additional data entry that an electronic chain of custody system hasn't provided.
Screening provides a preliminary evaluation for drugs of abuse. While cost-effective for excluding drug use in most samples, positive screening results require confirmation for legal acceptance. Any preliminarily positive samples in Screening necessitate further confirmation.
If a sample tests preliminarily positive during Screening, more hair is extracted from the original specimen for the Extraction phase. Drugs are isolated from hair at much lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening the most complex method to execute.
Confirmation of any positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All preliminary positive samples undergo washing before confirmation as necessary. The complete lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
