Hair analysis is recognized as an efficient means for identifying drug and alcohol use. The hair maintains a chronological record of drug and alcohol consumption by embedding biomarkers within its strands. When cut close to the head, hair samples offer an approximate prospective 3-month detection interval for substances like alcohol and drugs. The sample collection process is straightforward, tampering with the sample is relatively challenging, and the samples are simple to mail.
Acquiring a 1.5-inch hair portion from near the scalp, encompassing roughly 200 hairs (similar to the thickness of a #2 pencil), will provide 100mg of hair, which is suitable for both initial tests and confirmation. For analyses such as EtG or those exceeding 10 panels, a sample of 150mg is suggested. It is advisable to use a jeweler’s scale to weigh the specimen. If head hair is inaccessible, a comparable quantity of body hair can be used. "Head hair" refers specifically to hair from the scalp, whereas "body hair" includes all other types like facial and underarm hair.
Process Overview
The drug test laboratory procedure consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample's initiation into the lab’s database occurs. This step ensures that the sample was appropriately sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and supplements any missing data not provided electronically by the custody chain system.
Screening is a preliminary assessment for potential drug abuse. Although Screening offers an economical approach to exclude drug consumption in most samples, any positive findings must undergo Confirmation for court admissibility. Presumptive positive samples detected in Screening necessitate additional confirmation testing.
If an initial Screening test indicates a presumptive positive, additional hair is drawn from the original sample for the Extraction process. This stage involves retrieving drugs from hair at notably lower concentrations compared to other methods such as urine or oral fluid testing, which highlights the complexity of hair drug analysis.
Confirmation of any positive Screening outcomes is executed through techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples presumed positive are cleaned as necessary. The full laboratory sequence from Accessioning to Confirmation undergoes CAP (College of American Pathologists) Hair designation review and is accredited under ISO / IEC 17025 standards.
