Hair testing is now perceived as an effective method for identifying drug and alcohol use. Hair offers a prolonged record of alcohol and drug consumption by encapsulating biomarkers within its strands. When taken near the scalp, hair enables approximately a three-month detection window for alcohol and drug use. Hair collection is straightforward, challenging to tamper with, and convenient for shipping.
A 1.5-inch segment of around 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is optimal for examination and validation. For EtG, additional tests, or those exceeding 10 panels, 150mg of hair is suggested. It's advisable to measure the sample using a jeweler’s scale. If scalp hair isn't available, an equivalent amount of body hair may be used. When we mention head hair, we exclusively refer to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
There are four key phases in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the primary processing of a sample into a lab's system. This step includes checking that the sample was properly sealed and dispatched, assigning it a random Laboratory Accessioning Number (LAN), and completing any missing data entry not available via an electronic chain of custody system.
Screening provides an initial rapid assessment for drug abuse. While Screening offers a cost-efficient method to dismiss drug use for most samples, a positive screen necessitates confirmation for court acceptance. Any samples that test positive in Screening require a follow-up confirmation.
Should a sample test positive during Screening, more hair is taken from the initial sample and prepped for Extraction. At this phase, drugs are extracted from hair at much lesser concentrations than in urine or oral fluid, which is why hair drug screening is complex to execute.
The Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples that test positive are cleansed before confirmation as necessary. The complete lab process, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.
