The utilization of hair testing has been recognized as an effective means for identifying drug and alcohol consumption. Hair captures long-term biomarker evidence of alcohol and drug use within the strands of hair as they grow. When hair is sampled close to the scalp, it can reveal drug and alcohol consumption over a period of nearly three months. The process of collecting hair is straightforward, making it somewhat resistant to tampering, and simple to transport.
Collecting a 1.5-inch piece consisting of around 200 hair strands (approximately the thickness of a #2 pencil) near the scalp yields 100mg of hair, which is an optimal sample amount for analysis and validation. For EtG, additional tests, or panels exceeding ten, it is recommended to gather 150mg of hair. We suggest using a jeweler’s scale for weighing the sample. If scalp hair cannot be obtained, equivalent body hair may be used. References to head hair pertain exclusively to scalp hair, while body hair denotes all other types including facial and axillary hair.
Process Overview
The key procedures in processing a drug test result in the laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning integrates a sample into the laboratory system by verifying proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and addressing any incomplete data entry that might be absent from an electronic chain of custody system.
Screening allows for a preliminary and cost-effective assessment for drug abuse. Although Screening efficiently omits the majority of negative samples, a positive result must undergo confirmation for legal admissibility. Any samples that yield a presumptive positive during Screening require additional confirmation testing.
Should a sample yield a presumptive positive in Screening, further hair is extracted from the initial specimen and readied for Extraction. At this phase, substances are leached from hair in concentrations lower than in other testing methods (for instance, urine or oral fluid), which contributes to the complexity of hair drug testing.
Positive findings are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that are presumptively positive receive washing before undergoing confirmation, if necessary. The step-by-step laboratory procedures, spanning from Accessioning through Confirmation, are scrutinized under CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.
