Hair testing is now regarded as an effective method for identifying drug and alcohol consumption. Hair traps biomarkers within its fibers, offering a comprehensive timeline of alcohol and drug use. Collected near the scalp, it provides a detection window of up to three months for substances. It's easy to gather, hard to tamper, and straightforward to transport.
A 1.5-inch segment containing around 200 hair strands (similar to the size of a #2 pencil) cut near the scalp yields 100mg of hair, the perfect amount for testing. For EtG, additional tests, or tests exceeding 10 panels, a 150mg sample is advised. It's best to weigh the sample using a jeweler's scale. In the absence of scalp hair, an equal quantity of body hair is acceptable. The term 'head hair' only includes scalp hair, while 'body hair' covers all other types (face, armpits, etc.).
Process Overview
The key steps in the laboratory procedure for processing a drug test result are Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, a sample is initially processed into the lab's system. This involves ensuring the sample was sealed and shipped correctly, assigning it a random LAN (Laboratory Accessioning Number), and completing any pending data entry not already covered by an electronic chain of custody system.
Screening is a preliminary examination for substances of abuse. Although cost-efficient for eliminating drug use for most samples, a positive screen requires confirmation for court admissibility. Any samples flagged as presumptively positive require additional verification.
If a sample tests presumptively positive at the Screening phase, additional hair is extracted from the original specimen and prepared for Extraction. At this stage, drugs are removed from the hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), highlighting why hair drug testing is among the toughest methodologies.
Confirmation of a positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives are washed prior to confirmation if necessary. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation.
