Hair testing is now recognized as a potent method for identifying drug and alcohol usage. Hair entraps biomarkers within the fibers of its growing strands, offering a lengthy record of alcohol and drug consumption. Hair collected near the scalp can provide a detection window of up to roughly 90 days for alcohol and drugs. It is easy to collect, hard to tamper with, and simple to transport.
A sample of 1.5 inches consisting of about 200 hairs (approximately the width of a #2 pencil) taken nearest to the scalp will produce 100mg of hair, the optimum sample for screening and confirmation. For EtG, additional tests, and/or tests above 10 panels, 150mg of the sample is advised. We suggest measuring the sample using a jeweler’s scale. If scalp hair is not present, an equivalent quantity of body hair can be collected. "Head hair" refers exclusively to scalp hair. "Body hair" encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The key steps in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial processing of a sample within a laboratory’s system. This includes confirming the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry not provided by an electronic chain of custody system.
Screening performs a preliminary check for drugs of abuse. Although Screening is an economical means to exclude drug usage in most samples, a positive result requires confirmation to be valid in legal contexts. Any samples with a presumptive positive in Screening undergo secondary confirmation.
If a result is presumptively positive during Screening, additional hair is retrieved from the initial sample and prepared for Extraction. During this phase, drugs are extracted from hair at much lower concentrations than in other procedures (such as urine or oral fluid), making hair drug screening the most challenging method to conduct.
The confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation as needed. The full lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair guidelines and the accreditation to ISO / IEC 17025 standards.
