The use of hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair strands capture biomarkers within their fibers, offering a comprehensive record of substance use over an extended period. When extracted near the scalp, the hair can reveal alcohol and drug presence for roughly three months. It's easy to collect, relatively resistant to tampering, and simple to transport.
For optimal screening and confirmation, a 1.5-inch sample encompassing about 200 strands of hair close to the scalp yields 100mg, which is ideal. For EtG, additional analyses, or those exceeding 10 panels, a 150mg specimen is advisable. Using a jeweler's scale to weigh the sample is recommended. If scalp hair is not obtainable, equivalent body hair can be collected instead. In our context, head hair pertains to scalp hair solely, while body hair encompasses other hair types such as facial or axillary hair.
Process Overview
Laboratory processing of drug tests involves four core stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary integration of a specimen into a lab's system, confirming proper sealing and transport, assigning a unique LAN (Laboratory Accessioning Number), and filling in any data entries absent from an electronic chain of custody.
Screening offers an initial brief assessment for drug misuse. While it serves as a cost-efficient means to exclude drug usage for most samples, any positive findings require confirmation for legal admissibility. Samples with presumptive positivity in Screening are subject to further verification.
In cases where a sample tests as presumptively positive during Screening, additional hair is taken from the specimen for Extraction. This phase involves extracting drugs from hair at lower concentrations than other methods like urine or oral fluids, accounting for hair testing's intricate complexity.
Positive Screening outcomes are validated through GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample undergoes washing before confirmation, if needed. The comprehensive lab process, from Accessioning to Confirmation, adheres to CAP (College of American Pathologists) Hair designation alongside the ISO/IEC 17025 accreditation.
