Hair testing is recognized as a powerful means of identifying drug and alcohol use. Hair records a lengthy history of alcohol and drugs by preserving biomarkers within the fibers as the hair strand grows. When hair is taken close to the scalp, it can reveal drug and alcohol use for up to around three months. Hair collection is straightforward, challenging to tamper with, and easy to send.
A 1.5-inch segment of approximately 200 hair strands, which is about the width of a #2 pencil, near the scalp, will provide 100mg of hair, the optimal quantity for evaluation and verification. For EtG, additional tests, and/or panels over 10, it is advisable to gather 150mg of hair. It is suggested to use a jeweler’s scale for measuring the sample. If there is no scalp hair, a similar amount of body hair can be used. When referring to head hair, it pertains exclusively to scalp hair. Body hair includes all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result consists of the steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary processing of a specimen into the laboratory system. This step ensures the sample is sealed and sent correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data that an electronic chain of custody system does not provide.
Screening carries out a preliminary rapid assessment for substances of abuse. Though cost-efficient for excluding drug use in most samples, any positive screen demands confirmation for court admissibility. Samples presumptively positive during Screening need secondary confirmation.
For samples indicating positivity in Screening, additional hair is extracted from the initial sample and readied for Extraction. Here, drugs are extracted from the hair at much lower concentrations than in other methods (e.g., urine, oral fluid), making hair drug screening the most challenging approach.
Confirmation of any positive screening outcome is done using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing prior to confirmation if needed. The complete laboratory pathway from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standard accreditation.

Note: Although frequently termed as "hair follicle tests", the examination itself analyzes the hair strand rather than the follicle beneath the scalp.
