Hair testing is recognized as an effective method to identify drug and alcohol consumption. Hair serves as a repository for a prolonged period, capturing biomarkers within the strands' fibers. When collected near the scalp, it provides a detection window of around three months for substances. Hair samples are easy to collect, less prone to tampering, and straightforward to transport.
Obtaining a 1.5-inch hair segment with roughly 200 strands (similar in size to a #2 pencil) adjacent to the scalp will result in 100mg of hair, which is suitable for screening and confirmation. For EtG, additional tests, or analyses beyond 10 panels, 150mg of the sample is recommended. Utilizing a jeweler’s scale for weighing the sample is advised. If head hair is not available, an equivalent amount of body hair can be used. 'Head hair' specifically denotes scalp hair. 'Body hair' covers all other types, including facial and axillary.
Process Overview
The key stages in the laboratory analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary processing of a sample into the lab system. This involves confirming the appropriate sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and handling additional data entry not available via an electronic chain of custody system.
Screening serves as an initial check for drugs of abuse. While it is cost-effective for ruling out drug usage in most samples, any positive screen requires further confirmation to be valid for legal purposes. Positives identified in Screening necessitate a secondary confirmation.
For presumptive positives identified in the Screening phase, additional hair is drawn from the original sample for Extraction. In this step, substances are extracted at much lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening a more complex technique.
Positive screening results are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a wash before confirmation as required. From Accessioning to Confirmation, the entire process is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Note: Although often called "hair follicle tests", the analysis targets the hair strand, not the follicle beneath the scalp.

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.
