Hair testing is now recognized as a potent method for detecting drug and alcohol usage. It captures biomarkers within the growing hair strand fibers, providing a long-term record of alcohol and drugs. A sample taken near the scalp can offer roughly a three-month window for detecting drugs and alcohol. Collecting hair is straightforward, a bit tough to tamper with, and convenient to transport.
A 1.5-inch hair sample of approximately 200 strands (about the width of a #2 pencil) closest to the scalp yields 100mg, ideal for screening and confirmatory tests. For EtG, add-ons, or tests above 10 panels, 150mg is preferred. It's advised to weigh the hair using a jeweler’s scale. If scalp hair is unavailable, a similar amount of body hair can be used. "Head hair" refers to scalp hair solely; "body hair" includes other hair types like facial and axillary.
Process Overview
The primary steps in processing a drug test in the lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab’s system. It involves verifying proper sealing and shipping, creating a random LAN (Laboratory Accessioning Number), and filling in any extra data not provided by an electronic chain of custody system.
Screening acts as a preliminary check for substance abuse. While it economically helps eliminate drug use on most samples, a confirmed positive screen is necessary for court acceptance. Presumptive positives from Screening need a secondary confirmation.
If Screening suggests a positive, more hair is extracted from the original specimen and processed for Extraction. Drugs are extracted at much lower concentrations from hair than from other tests like urine or oral fluid, making hair drug screening the most challenging technique.
Confirmation for any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleaned as needed before confirmation. The full lab process from Accessioning to Confirmation is evaluated under both CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation.

Note: Although often called "hair follicle tests", the test itself evaluates the hair strand, not the scalp's hair follicle.

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. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.
Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.
The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.
In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field.
