Hair tests have gained recognition as an effective method for identifying drug and alcohol consumption. Hair gives a prolonged history of substances by capturing biomarkers in the strands' fibers. When collected from near the scalp, hair can offer around a three-month detection period for substances. Hair collection is straightforward, hard to tamper with, and easy to send.
A 1.5-inch sample consisting of roughly 200 hair strands (comparable to a #2 pencil's diameter) nearest to the scalp yields 100mg, which is the optimal amount for analysis. For EtG, additional testing, or panels beyond 10, 150mg of the sample is advised. We advocate using a jeweler’s scale for measurement. If scalp hair is missing, the same quantity of body hair is an alternative. Reference to head hair specifies scalp hair alone. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing in drug test results involves four main phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage of processing a sample into the laboratory’s system. Tasks include verifying that the sample was properly sealed and dispatched, assigning a LAN (Laboratory Accessioning Number) randomly, and completing any extra data entry not available through an electronic chain of custody system.
Screening is a preliminary quick check for substances. While cost-efficient for eliminating drug usage in the majority of samples, a positive screening necessitates confirmation for court validity. All samples preliminarily positive in Screening need secondary confirmation.
If Screening indicates a presumptive positive, additional hair is extracted from the initial sample for Extraction. During this phase, hair releases drugs at a far lower concentration compared to other methods (such as urine or oral fluid), highlighting the complexity of hair drug screening.
Confirmation for any positive screenings is done via GC/MS, GC/MS/MS or LC/MS/MS. Any presumptive positive samples undergo washing as needed before confirmation. The complete lab process, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair criteria and accreditation under 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.
