The utilization of hair testing has gained traction as an effective method for identifying substance use of both drugs and alcohol. Hair captures biomarkers within the fibers of the hair shaft, offering a prolonged record of alcohol and drug consumption. When sampled near the scalp, hair can reveal a detection period of up to three months for these substances. It's easy to collect, relatively hard to tamper with, and convenient to transport.
To obtain the ideal sample for analysis and confirmation, a 1.5-inch segment (about the circumference of a #2 pencil) comprising around 200 hairs closest to the scalp will weigh 100mg. For tests involving EtG, added elements, or more than ten panels, a 150mg specimen is advisable. The use of a jeweler’s scale for weighing the sample is suggested. Should scalp hair be unobtainable, an equivalent volume of body hair can be taken. Head hair specifically refers to scalp hair, while body hair encompasses other types such as facial and underarm hair.
Process Overview
The laboratory drug testing protocol encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning denotes the initial integration of a sample into the laboratory system. This incorporates validating the sample's proper sealing and shipment, generating a random LAN (Laboratory Accessioning Number), and fulfilling any supplementary data inputs not completed by an electronic chain of custody system.
Screening serves as a preliminary examination for drugs. Though a cost-efficient measure for excluding drug usage in most samples, a favorable screening outcome necessitates confirmation for legal validity. Any samples preliminarily positive in the Screening phase require a further confirmation step.
In instances of a presumptive positive result during Screening, additional hair is sourced from the original sample in preparation for Extraction. At this stage, drugs are isolated from hair in much lesser concentrations compared to other methods (e.g., urine or oral fluid), rendering hair drug screening the most challenging methodology.
Confirmation for any positive screening results employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. Prior to confirmation, all presumptively positive samples undergo a washing process, if needed. The comprehensive lab process from Accessioning to Confirmation adheres to the criteria of the CAP (College of American Pathologists) Hair categorization and complies with ISO / IEC 17025 accreditation 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.
