Hair analysis is increasingly recognized as a robust method for identifying alcohol and drug consumption. The hair shaft's fibers capture biomarkers over time, offering an extended historical record of substance use. When hair is sampled near the scalp, it can detect substances over a period of up to three months. Hair collection is straightforward, hard to tamper with, and convenient for transport.
An ideal specimen for evaluation and validation is a 1.5-inch segment of roughly 200 hair strands (comparable in size to a #2 pencil), weighing approximately 100mg. For EtG testing, additional panels, or beyond 10-panel tests, a 150mg sample is advised. Using a jeweler’s scale to measure the sample is suggested. When scalp hair is unavailable, the same quantity of body hair can be used. The term head hair specifically refers to scalp hair; body hair covers all other hair types (like facial and axillary).
Process Overview
The laboratory processing of a drug test comprises four major phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial introduction of a sample into a laboratory's system. This phase includes verifying the appropriate sealing and shipping of the sample, generating a random LAN (Laboratory Accessioning Number), and fulfilling any additional data entry that the electronic chain of custody system might have omitted.
Screening acts as a preliminary assessment for drug abuse indicators. While cost-efficient for eliminating drug presence in most samples, any positive finding from Screening requires further confirmation to meet legal admissibility. Samples that register a presumptive positive from Screening necessitate an additional validation process.
In instances of presumptive positive results during the Screening stage, additional hair is extracted from the original sample for the Extraction phase. In this stage, drug compounds are isolated at a significantly lower concentration than through other testing methods (such as urine or oral fluids), which underscores the complexity of hair drug analysis.
Confirmation of positive screening outcomes employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. Prior to confirmation, any presumptive positive samples undergo washing as necessary. The end-to-end laboratory procedure from Accessioning to Confirmation is under the oversight of both the CAP (College of American Pathologists) Hair standard and accreditation to ISO/IEC 17025 standards.
