Hair testing is recognized as an effective method for identifying drug and alcohol consumption. By capturing biomarkers in the fibers of hair strands as they grow, hair provides a comprehensive history of substance use. Collected from near the scalp, hair samples offer an approximate 3-month window for detecting drugs and alcohol. Collection is straightforward, tampering is relatively challenging, and shipping is uncomplicated.
A sample measuring 1.5 inches with roughly 200 hair strands (similar in size to a #2 pencil) near the scalp yields 100mg, the optimal amount for screening and confirmation. For EtG, additional tests, or panels exceeding 10, a 150mg sample is advised. Use a jeweler's scale for precise weighing. In the absence of scalp hair, an equivalent amount of body hair can be utilized. References to head hair imply only scalp hair, whereas body hair means all other types, including facial and axillary hair.
Process Overview
Processing a drug test result in the lab entails four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves entering a sample into a lab's system, ensuring the sample was sealed and shipped correctly, assigning it a random LAN (Laboratory Accessioning Number), and completing data entry missing from an electronic chain of custody system.
Screening represents an initial rapid test for drug abuse. While it is a cost-efficient method to exclude drug use in most cases, a positive result must be confirmed for legal admissibility. Presumptive positive samples require further confirmation.
If Screening indicates a presumptive positive, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are retrieved from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening one of the more complex methodologies.
Confirmation of positive screens is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Samples presumed positive undergo washing before confirmation if needed. The complete lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair standard and ISO / IEC 17025 accreditation.
