Hair testing is regarded as a robust method for identifying drug and alcohol usage. Hair captures a prolonged history of substance use by encasing biomarkers within the fibers as the hair grows. If gathered near the scalp, hair can offer about a 3-month detection span for drugs and alcohol. Hair collection is straightforward, somewhat resistant to tampering, and easy to transport.
A sample measuring 1.5 inches from around 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp yields 100mg of hair, the preferred amount for both screening and confirmation. For EtG, additional tests, or panels beyond 10, 150mg of the sample is suggested. It's best to weigh the sample using a jeweler’s scale. If scalp hair isn't available, the same amount of body hair may be taken. In context, head hair specifically refers to scalp hair only. Body hair encompasses all other types such as facial and axillary.
Process Overview
The process for generating laboratory drug test results involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample enters a lab’s system. This step verifies proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and fills in any missing data not captured by an electronic chain of custody system.
Screening involves a rapid initial assessment to detect commonly abused drugs. While Screening is a cost-efficient approach to dismiss drug use in most samples, a positive screening result needs confirmation to be valid in court. Any samples with a presumptive positive result from Screening demand further confirmation.
For samples showing a presumptive positive at Screening, additional hair is taken from the original sample for preparation during Extraction. At this stage, drugs are drawn from hair at a lower concentration compared to other methods (like urine or oral fluid), making hair drug screening a challenging method to implement.
Confirmation of positive screening outcomes is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Samples presumed positive are washed before confirmation if needed. The entire lab process from Accessioning to Confirmation adheres to the CAP (College of American Pathologists) Hair designation, alongside accreditation to ISO / IEC 17025 standards.

Note: While often named "hair follicle tests", the actual test analyzes the hair shaft and not the follicle beneath the scalp

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation.
