Hair testing is increasingly recognized as an effective means for identifying drug and alcohol consumption. It offers a prolonged history of drug intake since biomarkers become trapped within the strands of hair as it grows. A sample taken near the scalp can reveal substance use over a span of roughly three months. It is easy to collect, challenging to tamper with, and simple to mail.
Aiming for an ideal screening and confirmation sample, a 1.5-inch section comprising roughly 200 hair strands (comparable to the width of a #2 pencil) should yield about 100mg of hair. For extensive tests like EtG or those exceeding 10 panels, a sample of 150mg is advised. Using a jeweler’s scale is recommended for weighing. In the absence of scalp hair, a comparable quantity of body hair can be used. Note that when discussing head hair, the focus is solely on scalp hair. Body hair encompasses all other types (e.g., facial, axillary).
Process Overview
The laboratory processing stages for drug test results encompass four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with the sample's integration into the laboratory system. This step ensures proper sealing and shipping of the sample, assigns a unique LAN (Laboratory Accessioning Number), and completes any pending data entry absent in an electronic chain of custody system.
Screening offers a preliminary evaluation for drug abuse. It serves as a cost-efficient method to eliminate most samples from suspicion, though a positive result necessitates confirmation for legal acceptance. Presumptively positive samples identified during Screening require further confirmation.
In cases of presumptive positivity during Screening, additional hair is extracted from the original sample for the Extraction stage. This phase involves isolating drugs from hair at far lower concentrations compared to alternative methods (like urine or oral fluids), underlying hair drug testing's complexity.
Confirmation of any positive screening involves processes like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo necessary washing before confirmation. The entire workflow, from Accessioning to Confirmation, falls under the scrutiny of both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
