Hair analysis has emerged as an effective means for identifying drug and alcohol consumption. Hair captures biomarkers within the fibers of the maturing hair strand, offering an extended record of alcohol and drug exposure. When acquired near the scalp, hair can yield a detection window of approximately three months for substances. It is straightforward to gather, somewhat resistant to tampering, and convenient to transport.
A 1.5-inch snippet, comprising roughly 200 hairs (around the size of a #2 pencil) nearest to the scalp, will yield 100mg of hair, which is the preferred quantity for screening and validation. For EtG, enhancements, or tests exceeding 10 panels, 150mg of the sample is advised. We suggest measuring the sample on a jeweler’s scale. If scalp hair is missing, a comparable amount of body hair may be used. When mentioning head hair, we are exclusively referring to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The process of analyzing a drug test result in the lab includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning begins with bringing a sample into the laboratory’s system. This step confirms the sample's seal and proper dispatch, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data recording omitted by an electronic chain of custody mechanism.
Screening includes an initial swift evaluation for substances of abuse. Even though Screening is a budget-friendly method to dismiss drug use on most samples, a verification of a positive result is required for legal acceptability. Samples deemed presumptively positive in Screening demand additional confirmation.
For samples potentially positive at the Screening stage, more hair is taken from the initial sample and readied for Extraction. During this phase, drug extraction from hair occurs at a much lower concentration compared to other methods (e.g., urine or oral fluid), rendering hair drug screening the most challenging approach to execute.
Any positive Screening result must undergo Confirmation using GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples are washed before confirmation as required. The complete laboratory procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 certification.
