Considered a potent method in recognizing drug and alcohol consumption, hair testing offers an extensive timeline of substance use by capturing biomarkers within the strands of hair as they grow. When hair samples are obtained close to the scalp, they provide an approximate 3-month window for detecting alcohol and other substances. The process of collecting hair is straightforward, hard to alter, and easy to transport.
A sample measuring 1.5 inches with roughly 200 hairs (equivalent to a #2 pencil) nearest to the scalp will yield 100mg, perfect for screening and confirmation. For tests such as EtG, enhancements, or over 10-panel assessments, 150mg is suggested. We advise using a jeweler’s scale for weight measurement. If scalp hair isn't available, a similar quantity of body hair can be used. By head hair, we specifically mean scalp hair, while body hair encompasses all other hair types like facial and axillary hair.
Process Overview
The laboratory processes for a drug test result are divided into four fundamental steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary handling of a sample into the lab's system. This phase ensures the sample was sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and fills in any missing data not covered by an electronic chain of custody system.
Screening offers a quick preliminary check for potential drug use. Although cost-effective for ruling out drug usage in most samples, a positive screening needs further confirmation to be valid in judicial settings. Any samples flagged as presumptively positive at this stage require additional confirmation.
Should a screening test yield a presumptive positive, extra hair is taken from the original sample for the Extraction process. Here, drugs are removed from hair at significantly lower concentrations compared to methods like urine or oral fluid tests, emphasizing the complexity of hair drug screening.
Confirmation of a positive screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing before confirmation procedures if necessary. The complete laboratory process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
