Hair analysis is recognized as a robust method for uncovering alcohol and drug use. Hair strands capture biomarkers within their fibers, which offer a longer-term record of substance use. By taking samples near the scalp, a detection period of around 3 months is achievable for identifying alcohol and other substances. Hair is straightforward to gather, less prone to tampering, and convenient to send.
A 1.5-inch segment comprising roughly 200 hair strands (comparable to a #2 pencil's thickness) closest to the scalp yields 100mg of hair—this is the perfect amount for both screening and confirmation procedures. For EtG, additional tests, or those exceeding 10 panels, a greater quantity of 150mg is advised. Using a jeweler’s scale for weighing the specimen is recommended. In cases where scalp hair cannot be obtained, an equivalent quantity of body hair may be used. When discussing head hair, we mean scalp hair solely. Body hair pertains to all other hair varieties (such as facial and axillary).
Process Overview
The laboratory processing of a drug test result entails four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first stage where a sample is introduced to a lab’s system. This step ensures the sample was correctly sealed and sent, assigns a random Laboratory Accessioning Number (LAN), and completes any missing data entry that isn't provided by an electronic chain of custody system.
Screening serves as the initial check for drug abuse. Although it’s a cost-efficient method to dismiss drug use in most samples, any positive screening results need confirmation for them to be legally valid. Samples that test presumptively positive in Screening require additional confirmation.
Should a sample test positive during Screening, more hair is extracted from the initial sample to prepare for Extraction. This stage isolates drugs from hair at concentrations much lower than other methods like urine or oral fluid, rendering hair drug testing more challenging.
Positive screening outcomes undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all samples with presumptive positive results are cleansed as necessary. Every phase from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair designation and adheres to ISO/IEC 17025 accreditation standards.
