Recognized as an effective method for identifying drug and alcohol consumption, hair testing provides a lengthy historical record by capturing biomarkers within the growing hair strand's fibers. When taken near the scalp, hair can offer roughly a 3-month window for detecting alcohol and other substances. The collection of hair is straightforward, relatively resistant to tampering, and easy to transport.
A specimen of 1.5 inches, comprising around 200 strands (approximately the diameter of a #2 pencil) closest to the scalp, yields 100mg of hair, the optimal sample for both initial screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg of hair is advised. It is suggested to measure the sample using a jeweler’s scale. If scalp hair is not present, an equivalent amount of body hair may be used. When mentioning head hair, it is specific to scalp hair alone. Body hair encompasses all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of integrating a sample into a lab's system, which includes verifying proper sealing and shipping of the sample, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing additional data input not already provided by an electronic chain of custody system.
Screening consists of an initial rapid examination for substances of abuse. Although Screening is a cost-efficient method to exclude drug usage for the majority of samples, a positive screen must be confirmed for court acceptance. Any sample that tests positive in Screening mandates a secondary confirmation.
For samples showing presumptive positivity during Screening, more hair is extracted from the primary specimen for Extraction. In this phase, drugs are retrieved from hair at a much lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening a highly complex methodology.
Confirmation of any positive Screen result is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed before confirmation as necessary. The full laboratory process, from Accessioning to Confirmation, is scrutinized in accordance with CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
