Using hair testing has emerged as an effective approach for identifying drug and alcohol consumption. Hair traps biomarkers within its expanding strands, offering a prolonged history of substance use. When collected near the scalp, hair can potentially reveal alcohol and drug use for up to around 90 days. Hair collection is straightforward, tough to tamper with, and simple to transport.
A sample of 1.5 inches approximately 200 hairs (roughly the size of a #2 pencil) from the scalp will yield 100 mg of hair, the perfect amount for testing and verification. For EtG, additional tests, and multiple panel tests beyond 10, 150 mg is advised. It is advisable to weigh the sample using a jeweler’s scale. If scalp hair isn't available, an equivalent amount of body hair can be used. By head hair, we mean scalp hair exclusively. All other hair types (e.g., facial, axillary) are called body hair.
Process Overview
The lab processing stages in a drug test result consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning is about integrating the sample initially into the laboratory system. This ensures the sample was correctly sealed and shipped, a LAN (Laboratory Accessioning Number) is assigned, and any remaining data from a non-electronic chain of custody system is completed.
Screening performs a quick check for substance abuse. While it’s a cost-effective method to eliminate drug usage in most samples, a positive screen needs confirmation for legal admissibility. Presumptive positive samples from Screening require further confirmation.
Should a sample prove presumptively positive in Screening, additional hair is used and prepared for Extraction. This phase extracts drugs from hair at significantly lower concentrations than other methods like urine or oral fluid, making hair drug screening the most intricate method available.
Any positive screening outcomes are validated through GC/MS, GC/MS/MS, or LC/MS/MS procedures. Before confirmation, all presumptive positive samples are washed as necessary. The laboratory processing from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair regulation and aligns with ISO / IEC 17025 accreditation.
