The utilization of hair testing has emerged as a significant method for identifying drug and alcohol consumption. Hair strands can reflect extended histories of alcohol and drug usage by embedding biomarkers within their growing fibers. When sampled close to the scalp, hair can reveal a detection window of nearly 90 days for alcohol and drugs. Collecting hair is straightforward, relatively resistant to tampering, and easy to transport.
A 1.5-inch segment consisting of approximately 200 hair strands (similar to the thickness of a #2 pencil) from the scalp will yield 100mg of hair, which is optimal for both screening and confirmation tests. For EtG and additional tests exceeding 10 panels, a specimen amount of 150mg is advised. Using a jeweler's scale is suggested for weighing the sample. If scalp hair is absent, a matching amount of body hair can be collected. When mentioning head hair, it specifically means scalp hair only, whereas body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory drug test result process comprises four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step where a sample is admitted into a lab's system. This step entails checking that the sample is sealed and properly sent, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any extra data entry required beyond what an electronic chain of custody system provides.
Screening provides a rapid initial assessment for drugs of abuse. Although Screening is a cost-efficient approach to exclude drug use in most samples, a positive result demands confirmation for legal acceptability. Samples that test presumptively positive during Screening necessitate secondary confirmation.
Should a sample test presumptively positive at the Screening phase, extra hair is retrieved from the original sample and readied for Extraction. At this phase, drugs are drawn from hair in much lower concentrations compared to other methods (such as urine or oral fluid), highlighting hair drug screening as intricate to perform.
Confirmation for any positive Screen result occurs via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before Confirmation if needed. Every step from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and meets ISO / IEC 17025 accreditation standards.
