Hair testing is recognized as a potent method for identifying drug and alcohol consumption. The hair captures biomarkers in the strands as they grow, offering a historical record of alcohol and drug intake. When collected near the scalp, hair can reveal up to a 3-month detection period for substances. The sample is easy to gather, difficult to tamper with, and simple to transport.
A 1.5-inch segment of approximately 200 hair strands (roughly equivalent to a #2 pencil diameter) from the closest point to the scalp results in a 100mg hair collection, which is optimal for testing and validation. For EtG, additional tests, and/or assessments above 10 panels, a 150mg sample is advisable. We suggest measuring the sample using a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair can be obtained. Reference to head hair implies scalp hair only. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The drug test laboratory processing involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the introductory processing of a sample within a laboratory's framework. This stage includes verifying the proper sealing and shipping of the sample, assigning a random Laboratory Accessioning Number (LAN), and completing any extra data entry absent from an electronic chain of custody system.
Screening performs an initial swift verification for substance misuse. Although a cost-efficient method to exclude drug consumption for most samples, a positive result in Screening requires validation for court admissibility. Any samples initially positive in Screening necessitate further confirmation.
Should a sample test presumptively positive during Screening, additional hair is extracted from the original sample and prepared for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations compared to other methods (like urine or oral fluid), making hair drug testing the most intricate process.
Confirmation of any positive Screening outcome is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All initial positive samples undergo washing before Confirmation, as required. The comprehensive laboratory procedure from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.
