Hair analysis is regarded as an effective method for identifying drug and alcohol consumption. Hair captures biomarkers over time within the fibers of a growing strand, delivering a historical record of substance use. When gathered near the scalp, hair provides up to a roughly 3-month detection period for alcohol and drugs. It's easy to gather, somewhat tricky to tamper with, and convenient to transport.
A 1.5-inch section of approximately 200 hair strands (comparable to the circumference of a #2 pencil) nearest the scalp yields 100mg of hair, the preferred amount for screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, a 150mg sample is advisable. Utilize a jeweler’s scale for measurement. Should scalp hair be unavailable, an equivalent portion of body hair can be used. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory drug test procedure includes Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails incorporating a sample into the laboratory system. This step ensures the sample was properly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and completes any additional data entry absent from an electronic chain of custody system.
Screening acts as an initial simple check for substances. While it is cost-effective for ruling out drug use in most samples, a positive screening must be substantiated to be legally valid. Samples that yield a positive result in Screening require further confirmation.
Should a sample result in a presumptively positive Screening, more material is drawn from the original specimen for Extraction. In this phase, substances are extracted from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), underscoring the complexity of hair drug testing.
Verification of positive screening outcomes is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are washed when necessary. The entire lab process from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
