Utilizing hair testing has emerged as an effective means for detecting both drug and alcohol usage. Hair captures a comprehensive history by embedding biomarkers within the strands as they grow. When collected close to the head, it can provide a detection period of up to roughly three months for drugs and alcohol. It's easy to collect, tough to tamper with, and simple to transport.
By gathering a 1.5-inch segment of around 200 hair strands (approximately the diameter of a #2 pencil) closest to the scalp, you obtain 100mg, the optimum sample size for both screening and confirmation. For EtG, additional analyses, and/or tests beyond ten panels, a 150mg sample is preferred. We advise measuring the specimen with a jeweler’s scale. If scalp hair isn't available, an equivalent amount of body hair can be obtained. By head hair, we specifically mean scalp hair. Body hair refers to everything else (facial, axillary, etc.).
Process Overview
The laboratory handling of a drug test result encompasses four critical phases: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, a sample is initially processed into the lab's system. This step ensures the sample was sealed and sent correctly, issues a random LAN (Laboratory Accessioning Number), and completes any outstanding data entry absent from an electronic chain of custody system.
Screening involves a prompt preliminary check for substance use. Although screening is a cost-efficient way to exclude drug use for most samples, a positive screen mandates confirmation for legal acceptability. Presumptive positives from Screening demand secondary verification.
Should a sample show presumptive positivity in Screening, more hair is collected from the initial sample for Extraction. Here, substances are isolated from hair at far lower concentrations than other methods (e.g., urine or saliva), making hair drug screening particularly complex to execute.
Any positive screening outcome is validated through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation if necessary. Each laboratory step from Accessioning to Confirmation falls under the scrutiny of both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
