Hair testing has emerged as a strong method for identifying drug and alcohol consumption. Hair retains a long-lasting record of substances by embedding biomarkers within the strands of hair as it grows. When taken near the scalp, hair may offer nearly a 3-month timeframe for detecting drugs and alcohol. Collecting hair is straightforward, relatively hard to tamper with, and simple to transport.
A 1.5-inch portion of about 200 hairs (roughly comparable to a #2 pencil) closest to the scalp yields 100mg of hair, optimal for testing and validation. For EtG, additional analyses, and/or tests consisting of more than 10 panels, 150mg of the sample is suggested. It's advisable to measure the sample using a jeweler’s scale. If scalp hair isn't available, an equal quantity of body hair can be used. By head hair, we mean scalp hair only, while body hair pertains to all other hair types (facial, axillary, etc.).
Process Overview
The lab processing of a drug test result involves four crucial steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab's system. This process includes confirming the sample was properly sealed and transported, allocating a random LAN (Laboratory Accessioning Number), and filling in any missing data not captured by an electronic chain of custody system.
Screening involves a preliminary rapid analysis for drug indications. Though Screening efficiently excludes drug usage in most samples, a positive result requires confirmation for courtroom eligibility. All samples that test positive in Screening need a further confirmation step.
If a sample shows positive results in Screening, additional hair is extracted from the original specimen for the Extraction phase. Here, drugs are isolated from hair at concentrations lower than those in other testing methods (e.g., urine or oral fluid), making hair drug testing the most challenging to execute.
Confirmation of any preliminary positive outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples with provisional positive results are cleansed before confirmation if needed. The complete lab process, from Accessioning to Confirmation, is reviewed in accordance with both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
