Hair testing has increasingly been recognized as a robust method for identifying drug and alcohol consumption. Hair offers a comprehensive history of substance use by encasing biomarkers in the strands as they grow. Collected near the scalp, hair can reveal drug and alcohol use for up to roughly three months. Its collection is straightforward, it's relatively resistant to tampering, and it can be easily transported.
A sample measuring 1.5 inches and consisting of roughly 200 hair strands (similar in size to a #2 pencil) taken closest to the scalp will provide 100mg of hair, which is the ideal quantity for screening and confirmation. For EtG, additional screens, and/or tests exceeding 10 panels, a 150mg specimen is suggested. Using a jeweler’s scale to measure the specimen is advised. If no scalp hair is available, an equivalent amount of body hair may be used. References to head hair specifically mean scalp hair only. Body hair encompasses all other hair types (such as facial and axillary hair).
Process Overview
The laboratory processing of a drug test involves four predominant phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial processing of a sample into a lab’s system. It entails checking that the sample was properly sealed and dispatched, assigning a random Laboratory Accessioning Number (LAN), and finalizing any outstanding data entry absent from an electronic chain of custody system.
Screening involves a preliminary rapid analysis for illicit substances. While Screening is an economical approach for evaluating the absence of drugs in most samples, any positive screen result requires verification to be admissible in legal contexts. Samples that initially test positive during Screening undergo secondary confirmation.
Should a sample initially test positive during Screening, an additional quantity of hair is extracted from the original sample and processed for Extraction. In this phase, substances are isolated from hair at much lower concentrations compared to other methods (such as urine or oral fluid), which explains why hair drug testing is the most complex method to execute.
Verification of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample is cleansed before confirmation as necessary. The complete lab procedure, from Accessioning to Confirmation, complies with the guidelines of both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.
