Hair analysis has emerged as a strong method for identifying drug and alcohol consumption. Hair captures a prolonged record of substance use, holding biomarkers within the fibers of its developing strands. When sampled near the scalp, it can provide an approximate 3-month window for detecting alcohol and drugs. It is easy to collect, hard to tamper with, and convenient to transport.
A 1.5-inch sample of around 200 hair strands (approximately the thickness of a #2 pencil) taken closely from the scalp will yield 100mg of hair, which is the perfect amount for testing and verification. For EtG, enhancements, and/or checks exceeding 10 panels, it is advised to collect 150mg of the sample. We suggest using a jeweler's scale to weigh the sample. If scalp hair cannot be obtained, the same weight of body hair can be used instead. Head hair specifically refers to scalp hair, while body hair denotes all other types (e.g., facial, underarm, etc.).
Process Overview
The drug test process in the lab encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the process of entering a sample into a lab’s workflow. This step includes ensuring the sample's seal and shipment were intact, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data not covered by an electronic chain of custody system.
Screening serves as a preliminary test to identify substance use. Although screening is an economical method effective at excluding drug use for most samples, it is crucial to confirm a positive screen before it is court-acceptable. Samples showing a potential positive in Screening necessitate further confirmation.
If Screening suggests positivity, more hair is prepared from the original specimen for Extraction. This phase involves retrieving drugs from hair at much lower concentrations than other methods (such as urine or saliva), marking hair drug testing as the most complex methodology to perform.
Confirming a positive screen result is done using GC/MS, GC/MS/MS or LC/MS/MS techniques. Prior to Confirmation, all samples with potential positive results undergo washing as necessary. The full lab process from Accessioning to Confirmation is verified under the CAP (College of American Pathologists) Hair designation and aligns with the ISO / IEC 17025 benchmarks.
