The utilization of hair testing has emerged as an effective means for identifying drug and alcohol consumption. Hair strands capture a long-term record of substances by preserving biomarkers within the fibers as they grow. When collected near the scalp, it can offer a detection span of up to roughly three months for alcohol and drugs. Collection is straightforward, tampering is relatively challenging, and shipping is convenient.
A 1.5-inch segment containing roughly 200 hair strands (comparable to a #2 pencil) nearest to the scalp produces 100mg, an optimal sample quantity for examination and validation. For EtG, additional analyses, and tests exceeding 10 panels, 150mg is suggested. It’s advisable to measure the sample using a jeweler’s scale. If scalp hair isn’t available, an equivalent volume of body hair can be collected. By head hair, we mean scalp hair exclusively. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The primary steps included in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the introductory integration of a sample into a lab’s database. This step verifies the sample’s proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data input not present in an electronic chain of custody system.
Screening offers a preliminary rapid evaluation for substances of abuse. While Screening serves as a budget-friendly method to dismiss drug use in most samples, a positive result requires confirmation for court admission. Any samples showing positive indications in Screening necessitate further confirmation.
If a sample tests positive in Screening, additional hair is extracted from the original specimen and readied for Extraction. This is where substances are isolated from hair at significantly lower concentrations compared to other approaches (e.g., urine or oral fluid), making hair testing the most challenging methodology to execute.
Confirmation of all positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation as necessary. The complete lab procedure from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.
