Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of substance use by locking biomarkers within the strands as they grow. Samples taken near the scalp can offer an approximate 3-month detection span for identifying drugs and alcohol. It’s easy to obtain, relatively hard to tamper with, and simple to transport.
A 1.5-inch sample, consisting of roughly 200 hair strands (comparable to a #2 pencil in width), provides 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional panels, or tests exceeding 10 panels, it's advised to gather 150mg. Using a jeweler’s scale for weighing the sample is suggested. If scalp hair is not available, an equivalent amount of body hair can be used. When talking about head hair, we specifically mean scalp hair. Body hair covers other types such as facial and axillary hair.
Process Overview
The laboratory procedure for a drug test result encompasses four steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first stage, where a sample is registered into the laboratory's system. This process ensures the sample was correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and finishes any extra data input not handled by an electronic chain of custody system.
Screening is a quick preliminary test for common drugs of abuse. Although it’s a cost-efficient method to rule out drug use in most samples, a positive result in the Screening phase must be verified for court acceptance. Any samples that test positive in Screening must undergo additional confirmation.
If a sample is marked positive during Screening, additional hair is taken from the main specimen for Extraction. At this stage, drugs in hair are extracted at lower concentrations compared to other methods (e.g., urine or saliva), which contributes to hair drug testing being the most challenging method to execute.
Confirmation of any positive screening result is performed using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples preliminarily marked as positive are washed before confirmation if necessary. The full lab process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and is accredited to 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.
