Hair testing is now regarded as a potent method for identifying drug and alcohol consumption. Hair retains a long-term record of substances by embedding biomarkers within the growing strands. When obtained near the scalp, hair offers an approximate 3-month detection period for these substances. It's easy to collect hair, fairly resistant to tampering, and straightforward to transport.
A 1.5-inch segment of roughly 200 hair strands, akin to the diameter of a #2 pencil, taken near the scalp, yields 100mg of hair, the optimal amount for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, 150mg of hair is preferred. We advise weighing the hair on a jeweler’s scale. Should scalp hair be absent, an equivalent quantity of body hair may be used. When mentioning head hair, we refer solely to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test results involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial introduction of a sample into a lab's system. This step ensures the sample was correctly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any necessary data tasks not handled by an electronic chain of custody system.
Screening is a rapid preliminary test for drugs of abuse. While cost-effective for ruling out substance use in most samples, a positive screening result must be verified for legal acceptability. All samples testing positive in Screening require subsequent confirmation.
For samples with a positive result in the Screening phase, additional hair is extracted from the original sample for further processing in Extraction. Here, drugs are separated from hair at much lower concentrations than other tests (e.g., urine or oral fluid), emphasizing the complexity of hair-based drug testing.
To confirm any positive screening outcomes, methods such as GC/MS, GC/MS/MS, or LC/MS/MS are used. Before final confirmation, presumptive positive samples are washed as necessary. The entire laboratory workflow, from Accessioning to Confirmation, is conducted under the CAP (College of American Pathologists) Hair guidelines and in compliance with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although sometimes called "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the scalp.
