Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of substances like alcohol by embedding biomarkers within the fibers of the hair as it grows. When cut near the scalp, it can reveal drug and alcohol use for a period stretching up to roughly three months. The collection process for hair is straightforward, its tampering is relatively challenging, and it is convenient for delivery.
A sample measuring 1.5 inches with around 200 hair strands (comparable to a #2 pencil) nearest to the scalp will yield 100mg, the optimal amount for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a 150mg specimen is advised. We suggest using a jeweler’s scale for accurate specimen weighing. In instances where scalp hair is unavailable, an equivalent volume of body hair can be utilized. The term head hair refers specifically to scalp hair, whereas body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The comprehensive laboratory process for a drug test result includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step where a sample enters a lab's system. This step ensures correct sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and attends to any further data entry if not handled by an electronic chain of custody system.
Screening involves a preliminary rapid assessment for illicit substances. While it's a cost-efficient approach to exclude drug presence in most samples, a positive screening must be substantiated for legal matters. Any samples with a presumptive positive result in Screening require a follow-up confirmation.
In the case of a presumptive positive during Screening, additional hair is extracted from the original sample for the Extraction stage. Drugs are then extracted from hair at significantly lower concentrations than alternative methods (e.g., urine or oral fluid), adding to the complexity of hair drug analysis.
Positive screening results undergo Confirmation through techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are cleaned as needed. The complete laboratory operations from Accessioning to Confirmation are evaluated under the CAP (College of American Pathologists) Hair designation and adhere to ISO / IEC 17025 accreditation standards.
