Hair screenings have gained recognition as an effective method for identifying drug and alcohol consumption. Hair can preserve a comprehensive timeline of alcohol and drug intake by trapping biomarkers within the fibers of the developing hair strand. When cut near the scalp, hair offers an approximate 3-month period for detecting alcohol and other substances. The collection process is straightforward, somewhat resistant to tampering, and easy to transport.
A sample measuring 1.5 inches with about 200 hair strands (comparable to the thickness of a #2 pencil) taken from the scalp yields 100mg of hair, which is ideal for both screening and verification. For EtG, supplementary tests, and panels beyond 10, 150mg of the sample is advised. Utilizing a jeweler’s scale to weigh the specimen is recommended. If scalp hair is unavailable, a similar volume of body hair may be used. References to head hair specifically pertain to scalp hair. Body hair encompasses any other hair types (facial, axillary, etc.).
Process Overview
The drug test result processing within a laboratory comprises Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with processing the sample into the laboratory’s system. This step ensures that the sample is properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and fills in any missing data not provided by an electronic custody system.
Screening acts as a preliminary check for drug presence. Although it’s a cost-efficient way to eliminate drug usage on most samples, a positive result from Screening needs confirmation before being legal evidence. Any samples deemed presumptively positive require a subsequent confirmation.
Presumptively positive samples in the Screening phase undergo further hair extraction from the initial sample which is then prepared for Extraction. This stage involves isolating drugs from hair at much lower levels compared to other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.
Confirmation of positive Screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples found presumptive positive are cleaned as necessary before confirmation. The entire lab procedure from Accessioning to Confirmation is reviewed by both the CAP (College of American Pathologists) Hair designation and 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.
