Hair testing is recognized as a robust method for identifying drug and alcohol consumption. Hair captures biomarkers within the fibers of the growing strand, offering an extended timeline of alcohol and drug usage. When collected near the scalp, hair can reveal drug and alcohol use over an approximately 3-month period. Hair collection is straightforward, relatively tamper-resistant, and convenient for shipping.
A sample measuring 1.5 inches long, comprising around 200 strands (akin to a #2 pencil in size) nearest to the scalp, provides 100mg of hair, which is the optimal amount for screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, a 150mg sample is advised. It's suggested to measure the specimen using a jeweler’s scale. Should scalp hair be unavailable, an equivalent quantity of body hair can be used. The term head hair specifically refers to the scalp hair. Body hair denotes all other types (facial, axillary, etc.).
Process Overview
There are four primary phases in the laboratory processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning begins with integrating a sample into the laboratory system, which involves confirming the sample was sealed and transported correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry unmet by an electronic chain of custody framework.
Screening conducts a preliminary examination for drugs of abuse. Though Screening offers a cost-effective means to exclude drug usage in most samples, a positive result needs validation for legal acceptability. Samples showing presumptive positivity in Screening necessitate a secondary confirmation.
If Screening yields a presumed positive, additional hair is drawn from the original sample for Extraction. This step extracts drugs from hair at concentrations lower than those found in other methods (e.g., urine or oral fluid), underscoring why hair drug testing is most challenging to execute.
Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples receive a thorough washing before confirmation if needed. The entire lab process from Accessioning through Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
