Hair testing is increasingly regarded as a robust method for detecting drug and alcohol consumption. Hair captures a comprehensive history of alcohol and other substance use by embedding biomarkers within the strands of the growing hair. When samples are sourced close to the scalp, they can reveal an alcohol and drug detection window extending up to roughly 3 months. The collection of hair is straightforward, resistant to tampering, and simple to transport.
A 1.5-inch segment comprising roughly 200 hair strands (analogous to the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample size for conducting screening and confirmation tests. For testing EtG, add-ons, and/or analysis beyond 10 panels, a specimen weighing 150mg is advised. Utilize a jeweler’s scale to weigh the specimen accurately. If scalp hair is not an option, an equivalent quantity of body hair is acceptable. References to head hair specify scalp hair exclusively. Body hair encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
The laboratory process for drug test results entails four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of processing a sample within a laboratory’s system. This step ensures the sample was properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent from an electronic chain of custody system.
Screening provides an initial rapid assessment for drugs of abuse. Although Screening is an economical way to exclude drug use in most samples, a positive result needs confirmation to be valid in a legal context. Any samples testing presumptively positive in Screening necessitate further confirmation.
For samples that test presumptively positive during Screening, additional hair is extracted from the original specimen and readied for Extraction. In Extraction, drugs are retrieved from hair at notably lower concentrations compared to other methods (such as urine or oral fluid), highlighting the complexity of performing hair drug screening.
The Confirmation of any positive outcome from Screening is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples undergo necessary washing before confirmation. The whole laboratory procedure, from Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Limitations:
Note: Commonly labeled as "hair follicle tests", the test itself examines the hair strand rather than the follicle beneath the scalp
