Over recent years, the method of drug testing has increasingly included hair follicle drug tests. Many employers, courts, and substance abuse professionals are opting for hair drug tests over standard urine tests. Organizations with strict no-drug policies, as well as courts and probation officers, favor these tests. The main benefit is a longer detection window, up to 90 days, and the difficulty in tampering. However, for detecting recent usage within five days, urine tests remain unsurpassed.

Hair analysis is now recognized as an effective tool for identifying drug and alcohol usage. Hair captures a prolonged history of alcohol and drugs by embedding biomarkers within the strands of hair as they grow. When taken from near the scalp, hair can offer nearly a 3-month period for detecting alcohol and drugs. Hair is easy to collect, not easy to tamper with, and convenient to send.
A sample of 1.5 inches with about 200 hair strands (roughly the width of a #2 pencil) from closest to the scalp provides 100mg of hair, which is the best amount for screening and confirmation. For EtG, extras, and/or evaluations exceeding 10 panels, 150mg of the sample is advised. It's suggested to weigh the sample using a jeweler’s scale. If there’s no scalp hair available, a similar quantity of body hair may be gathered. References to head hair mean scalp hair only. Body hair includes all other types of hair (beard, underarm, etc.).
Process Overview
The essential steps in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the first stage of inputting a sample into a laboratory’s setup. This process verifies the sample’s seal and shipping, allocates a random LAN (Laboratory Accessioning Number), and inputs any data absent from an electronic chain of custody system.
Screening serves as an initial rapid drug test. While Screening offers an economical method to dismiss drug consumption on many samples, a positive result in Screening needs verification for legal acceptance. Any samples presumed positive during Screening require separate confirmation.
If Screening indicates a presumptive positive, additional hair is extracted from the primary sample for Extraction. In Extraction, drugs are separated from hair at lower concentrations compared to other techniques (like urine or oral fluid), making hair drug screening the most intricate method to execute.
Confirmation of positive screening is done through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples undergo washing before confirmation as necessary. The full lab procedure from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Note: Though often called "hair follicle tests," the test is performed on the hair strand, 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.
