The perception of hair testing as an effective method for identifying drug and alcohol consumption has grown. Hair offers a chronicle of alcohol and drug use by embedding biomarkers within the strands. When collected near the scalp, a hair sample can reveal up to a 3-month detection period for substances. Hair collection is straightforward, challenging to tamper with, and convenient for transport.
A sample of 1.5 inches, approximately 200 strands (the size of a #2 pencil) near the scalp, equates to 100mg of hair—ideal for both screening and confirmation. For EtG, additional tests, or those exceeding 10 panels, 150mg of the sample is advisable. It's recommended to weigh the sample using a jeweler’s scale. If scalp hair is not an option, an equivalent amount of body hair can be used. By head hair, we mean only scalp hair; body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
There are four primary steps in processing a drug test result in the lab: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is registered into the laboratory system. This involves confirming that the sample has been sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary additional data entry not available via an electronic chain of custody system.
The Screening phase consists of a preliminary check for common drugs of abuse. Though cost-effective, any positive screen result must be confirmed for legal use. Samples that are presumptively positive during Screening require further confirmation.
In cases where a sample is presumptively positive at the Screening phase, additional hair from the initial sample is prepared for Extraction. This step retrieves drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug tests complex to conduct.
Positive screening results are verified through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if necessary. The entire process from Accessioning to Confirmation is conducted following guidelines from CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
