Tracking alcohol and drug usage effectively, hair tests are a potent option. Hair naturally records a timeline of substance use, as biomarkers are preserved within the growing strand's fibers. Collecting hair from near the scalp can yield insights into 90 days of alcohol and drug use. Hair is easy to collect, typically secure against tampering, and straightforward to transport.
A sample size of 1.5 inches with around 200 hair strands—comparable to a #2 pencil's thickness—amounts to 100mg, ideal for both screening and confirmation. For EtG, additional tests, or tests exceeding 10 panels, 150mg is advisable. We suggest measuring the hair on a jeweler’s scale. In the absence of scalp hair, an equivalent amount of body hair is suitable for collection. "Head hair" refers exclusively to scalp hair, whereas "body hair" encompasses facial and axillary hair among other types.
Process Overview
The four core steps for processing a drug test result in the lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is about integrating a sample into the laboratory's system, ensuring shipping and sealing integrity, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data inputs missing from the electronic chain of custody system.
This step consists of a preliminary check for substance misuse. While it's economical to screen out non-usage, positive screens require confirmation for court acceptance. Any initial positive results necessitate further verification.
When a sample tests positive initially, further hair is extracted from the sample for preparation in the Extraction phase. Drug extraction from hair occurs at lower concentrations compared to urine or oral fluid methodologies, marking hair testing as a challenging approach.
Confirmation for any screening result signaling positive is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, presumptively positive samples are washed as necessary. The complete lab procedure—from Accessioning to Confirmation—is assessed under both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 standards of accreditation.
