Hair testing is increasingly regarded as an effective method for identifying drug and alcohol usage. Hair captures a long-term record of alcohol and other drugs by embedding biomarkers within the fibers of the continually growing hair shaft. When sourced near the scalp, hair offers up to a 3-month detection window for alcohol and other substances. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches with approximately 200 hairs (similar to a #2 pencil in diameter) near the scalp yields 100mg of hair, optimal for both screening and confirmation. For EtG, additional analyses, and/or tests exceeding 10 panels, a specimen weight of 150mg is suggested. We suggest using a jeweler’s scale for specimen weighing. If scalp hair is not available, an equivalent quantity of body hair may be used. References to head hair pertain exclusively to scalp hair, while body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The processing of a drug test result in the laboratory involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of entering a sample into a lab’s system. This process verifies that the sample is sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary data entry not included in an electronic chain of custody system.
Screening executes an initial rapid check for substance abuse. Despite being a cost-effective measure to rule out drug use for most samples, a positive screen must be verified to hold up in court. Samples that test presumptively positive during Screening necessitate further confirmation.
Should a sample appear presumptively positive during Screening, additional hair is extracted from the initial specimen and set for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations than in alternative methodologies (such as urine or oral fluid), underscoring why hair drug screening is the most intricate methodology to conduct.
Confirmation of any positive screening outcomes is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are cleansed as required. The entire lab process, from Accessioning to Confirmation, undergoes review under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards accreditation.
