Hair analysis is now recognized as an effective means for identifying drug and alcohol consumption. It offers an extended historical record of substance use by capturing biomarkers within the strands of growing hair. Hair gathered near the scalp can reveal a detection window of roughly up to three months for different substances. The process of obtaining hair samples is straightforward, challenging to tamper with, and convenient to transport.
Gathering a 1.5-inch segment consisting of around 200 hair strands (roughly equivalent to the thickness of a #2 pencil) nearest to the scalp yields 100mg, which is the optimal amount for screening and verification. For EtG, additional panels, and assessments greater than 10 panels, 150mg of the sample is preferred. It is advisable to measure the specimen using a jeweler's scale. In cases where scalp hair is not available, a comparable quantity of body hair can be used. "Head hair" specifically denotes scalp hair, whereas "body hair" encompasses all other types (such as facial or axillary hair).
Process Overview
The primary stages in processing a drug test result in the lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase of incorporating a sample into the lab's system. This process involves checking that the sample was properly sealed and delivered, assigning a unique Laboratory Accessioning Number (LAN), and finalizing any additional data entry absent from the electronic chain of custody records.
Screening is a preliminary rapid assessment for the presence of drugs. While it is an economical method to exclude drug consumption for most samples, any positive findings during the screening phase need confirmation to hold up in legal settings. Samples presumed positive during Screening require further verification.
For samples presumed positive during Screening, additional hair is extracted from the original sample and readied for Extraction. This stage involves extracting drugs from hair in significantly lower concentrations compared to other methods (such as urine or oral fluid), which is why hair drug screening is among the most challenging methodologies to execute.
Positive results from screening are further confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptively positive samples undergo washing as needed before the confirmation process. The entire lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Limitations:
Note: While often labeled as "hair follicle tests", the analysis actually examines the hair strand rather than the follicle beneath the scalp.
