Hair testing is recognized as an effective method for detecting drug and alcohol usage. The hair serves as a historical record of alcohol and drug intake by holding biomarkers within the strands of growing hair. When obtained near the scalp, hair can reveal drug and alcohol use for up to around a 3-month timeframe. Hair is easy to collect, difficult to tamper with, and simple to send.
A sample length of 1.5 inches composed of around 200 hair strands (approximately pencil-sized #2) near the scalp yields 100mg of hair, the ideal portion for screening and confirmation. For EtG, additional tests, and/or checks beyond 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale for weighing the sample. In the absence of scalp hair, a similar quantity of body hair can be used. Head hair solely pertains to scalp hair in this context. Body hair encompasses all other types of hair (for example, facial, and axillary).
Process Overview
The key stages in laboratory processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the process whereby a sample is first entered into the laboratory system. This step ensures the sample was sealed and shipped correctly, a LAN (Laboratory Accessioning Number) is assigned randomly, and completes data entry not covered by any electronic chain of custody system.
Screening performs an initial assessment for drugs of abuse. Screening is cost-efficient for ruling out drug use in most cases, but positive results from screening require confirmation to hold up in court. Samples testing presumptively positive in Screening need secondary confirmation.
In instances where a sample tests presumptively positive during Screening, additional hair from the initial sample is prepared for Extraction. This stage involves extracting drugs from hair in significantly lower concentrations than through other methods (e.g., urine or oral fluid), making hair drug testing the most complex methodology.
Confirmation of any positive screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that test presumptively positive undergo washing prior to confirmation as required. The complete laboratory process, spanning from Accessioning to Confirmation, is evaluated following both the CAP (College of American Pathologists) Hair designation and the accreditation standards of ISO / IEC 17025.

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.
