Hair analysis is now regarded as a robust method for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of the growing hair strand, hair offers an extended history of substance use. When collected near the scalp, it provides a detection window for alcohol and drugs of up to three months. Hair collection is straightforward, challenging to tamper with, and easy to transport.
A 1.5-inch hair sample comprising roughly 200 strands (equivalent to the size of a #2 pencil) from the scalp yields 100mg, which is ideal for screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg of hair is suggested. We advocate weighing the sample on a jeweler’s scale. If scalp hair can't be obtained, an equivalent amount of body hair is acceptable. References to head hair imply scalp hair only, whereas body hair includes facial, axillary, and other types.
Process Overview
The four key steps in the lab processing of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into a lab’s system. This step includes verifying that the sample is properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody.
Screening performs a preliminary check for drugs of abuse. Although cost-effective for excluding drug use in most samples, a positive screen must be confirmed to be court-admissible. Samples that test presumptively positive in Screening require secondary confirmation.
For samples testing positive in Screen, more hair is extracted from the original specimen for the Extraction phase. At this stage, substances are extracted at much lower concentrations compared to other methods (such as urine or oral fluid), making hair testing one of the most challenging methodologies.
Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed if required before confirmation. The entire lab process, from Accessioning to Confirmation, falls under the review of both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 standards accreditation.

Note: Often called "hair follicle tests", they analyze the hair strand rather than the follicle beneath the scalp.
