Hair testing is increasingly recognized for its effectiveness in detecting drug and alcohol consumption. Hair captures a long-term record of alcohol and drugs by embedding biomarkers within the fibers of the hair as it grows. When the hair is collected near the scalp, it can offer up to a 3-month period for detecting alcohol and drugs. Hair collection is straightforward, hard to tamper with, and convenient to transport.
A 1.5-inch section comprising roughly 200 hair strands (about the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal quantity for both screening and confirmation. For EtG, supplementary screens, or tests exceeding 10 panels, a recommendation of 150mg of the sample is advised. We suggest using a jeweler’s scale to weigh the specimen. In cases where scalp hair is not available, a similar quantity of body hair can be used. The term "head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The drug testing process in the laboratory consists of four major phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial procedure of integrating a sample into a laboratory’s system. This step checks that the sample was properly sealed and shipped, assigns an arbitrary LAN (Laboratory Accessioning Number), and finalizes any additional data entry not available through an electronic chain of custody.
Screening serves as a preliminary evaluation for drugs of misuse. While Screening offers a cost-efficient means to exclude drug use in most specimens, a positive screen must be confirmed for it to be legally viable. Samples that yield a presumptive positive in Screening necessitate a secondary verification.
For samples that test presumptively positive during the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. In this phase, drugs are extracted from hair at lower concentrations compared to alternative methods (e.g., urine or oral fluid), which makes hair drug screening a challenging method to execute.
The Confirmation of any positive screen is completed using GC/MS, GC/MS/MS, or LC/MS/MS methods. Samples with presumptive positive results are cleansed before Confirmation as required. The entire process from Accessioning through Confirmation is reviewed under the CAP (College of American Pathologists) Hair designation and under the accreditation of ISO / IEC 17025 standards.

Limitations:
Note: Though often termed "hair follicle tests", the analysis is conducted on the hair shaft and not the follicle beneath the scalp.
