Hair testing is recognized as an effective method for identifying the consumption of drugs and alcohol. It offers a comprehensive history of substance use by capturing biomarkers within the fibers of the growing hair. When obtained near the scalp, hair can reveal drug and alcohol use for up to around three months. Hair collection is straightforward, challenging to tamper with, and conveniently transportable.
A sample of 1.5 inches, comprising about 200 hair strands (approximately the diameter of a #2 pencil) nearest to the scalp yields 100mg, ideal for screening and confirmation. For tests involving EtG, add-ons, or over 10 panels, 150mg of hair is preferred. It's advisable to weigh the hair on a jeweler’s scale. If scalp hair cannot be used, the same quantity of body hair can be obtained. When referring to head hair, it indicates only scalp hair. Body hair includes all other hair varieties (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of processing a sample into the lab's system, ensuring the sample was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not captured through an electronic chain of custody system.
Screening involves a preliminary rapid assessment for drugs of abuse. While it’s a cost-efficient way to exclude drug use in most samples, a positive screen must be verified to be court-acceptable. Samples presumed positive in Screening require a subsequent confirmation.
If a sample is presumed positive during Screening, additional hair is extracted from the original sample and readied for Extraction. During Extraction, drugs are isolated from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), which makes hair drug testing the most challenging method to conduct.
Positive results from Screening undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are washed before confirmation as needed. The complete laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and 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.
