Hair analysis stands out as a significant method for identifying the use of drugs and alcohol. Hair strands provide insights into long-term usage by capturing biomarkers within the fibers as they grow. When cut near the scalp, hair offers an approximate detection timeframe of three months for drugs and alcohol. Collecting hair is straightforward, not easily tampered with, and convenient to transport.
A 1.5-inch segment of around 200 hairs (comparable to the girth of a #2 pencil) from close to the scalp yields 100mg, which is the optimal sample size for both screening and verification tasks. It is advisable to use 150mg for tests involving EtG, additional panels, or those exceeding 10 panels. Using a jeweler’s scale is suggested for specimen weighing. Should scalp hair be lacking, a similar volume of body hair can suffice. By head hair, we specifically mean hair from the scalp, whereas body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The central stages in the lab analysis process of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is first integrated into the lab's system. This step ensures the sample was sealed and transported correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any other data entries not covered by an electronic chain of custody setup.
Screening is a preliminary assessment for drug abuse substances. Although Screening is an economical way to exclude drug use in most samples, any positive results necessitate confirmation for court acceptance. Samples that test positive in Screening require subsequent verification.
For samples preliminarily positive during Screening, additional hair is taken from the original specimen for the Extraction stage. Here, drugs are extracted from the hair in much lower concentrations compared to other methods (such as urine or oral fluids), making hair drug screening the most challenging methodology to execute.
Verification of any positive screening outcome is achieved through methods like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned prior to confirmation if needed. Every step from Accessioning to Confirmation is reviewed in compliance with both the CAP (College of American Pathologists) Hair program and the ISO / IEC 17025 accreditation standards.
