The utilization of hair testing has evolved into a significant method for identifying drug and alcohol consumption. The fibers within the hair strands trap biomarkers, offering an extended history of substance use. Hair collected near the scalp can reflect usage within a 3-month timeframe for both alcohol and various drugs. The collection process for hair is straightforward, not easily tampered with, and convenient for shipment.
Collecting a 1.5-inch segment of approximately 200 hair strands (comparable to a #2 pencil) nearest to the scalp will yield 100mg of hair, which is optimal for analysis. For EtG, additional tests, and tests exceeding 10 panels, 150mg of the sample is advised. Utilizing a jeweler’s scale for accuracy is recommended. Should scalp hair be unavailable, an equivalent volume of body hair is acceptable. The term "head hair" specifically refers to scalp hair, while "body hair" encompasses all other hair types (such as facial and axillary).
Process Overview
The fundamental steps in the lab processing of a drug test outcome encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the initial incorporation of a sample into a laboratory’s database. This step ensures the sample was securely sealed and transported, assigns a random Laboratory Accessioning Number (LAN), and completes any necessary data entry absent from an electronic chain of custody record.
Screening involves a preliminary, rapid evaluation for drug substances. Although a cost-efficient approach to eliminate drug use for most samples, a positive screening necessitates confirmation for court admissibility. Any samples deemed presumptively positive entail a secondary confirmation phase.
When a sample exhibits presumptive positivity during Screening, additional hair is extracted from the original sample and prepped for Extraction. This phase involves extracting drugs from hair at notably lower concentrations compared to other methods (such as urine or oral fluid), marking hair drug screening as one of the most complex methodologies.
The Confirmation phase for any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples with presumptive positivity are cleansed prior to Confirmation as required. The comprehensive lab process, from Accessioning to Confirmation, is subjected to review under the CAP (College of American Pathologists) Hair criteria and complies with ISO/IEC 17025 certification standards.
