Hair analysis has emerged as a robust method for identifying alcohol and drug usage. The hair strand captures a prolonged record of substance exposure by encasing biomarkers within its growing fibers. When gathered near the scalp, it can detect substances over a span of nearly three months. The collection process is straightforward, resistant to tampering, and convenient for transport.
A sample of 1.5 inches or approximately 200 strands (similar to the thickness of a #2 pencil) nearest the scalp yields the optimal 100mg necessary for both screening and verification. For EtG, additional analyses, and tests exceeding 10 panels, 150mg is advised. Using a jeweler’s scale to weigh the sample is recommended. In the absence of scalp hair, an equivalent portion of body hair can be obtained. References to head hair specifically denote scalp hair, while body hair encompasses all other growth types (facial, axillary, etc.).
Process Overview
The primary stages in the laboratory drug testing process include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, samples undergo initial integration into the laboratory’s database. This step verifies the secure sealing and proper shipment of the sample, assigns a unique LAN (Laboratory Accessioning Number), and completes any missing details not covered by an electronic chain of custody system.
Screening constitutes a preliminary assessment for the presence of illicit substances. While it offers a budget-friendly approach to exclude drug presence in most samples, a positive outcome necessitates confirmation for courtroom validity. Samples that tentatively test positive during Screening require further confirmation.
Should a sample test tentatively positive in the Screening, additional hair is sourced from the original batch for the Extraction phase. Here, drug compounds are isolated from hair at an exceptionally diluted rate compared to other methods (e.g., urine or oral fluid), underscoring the complexity of performing hair drug screens.
Confirmation of positive findings is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All tentatively positive samples undergo a cleaning process as part of the confirmation phase. The entire sequence from Accessioning to Confirmation is evaluated according to both the CAP (College of American Pathologists) Hair criteria and accreditation under ISO / IEC 17025 standards.
