Hair testing is widely acknowledged as an effective means of identifying drug and alcohol consumption. Hair captures a historical record of these substances by encasing markers within the hair fibers as they develop. When hair is taken from near the scalp, it can offer an approximately 90-day detection period for both alcohol and drugs. This method of sample collection is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch hair sample containing around 200 strands (roughly the size of a #2 pencil) from the scalp offers 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional tests, or those testing beyond 10 panels, a specimen amount of 150mg is advised. Utilizing a jeweler’s scale for weighing the specimen is suggested. If scalp hair cannot be retrieved, an equal quantity of body hair can be utilized. Reference to head hair pertains exclusively to scalp hair, whereas body hair encompasses all other types (such as facial and axillary hair).
Process Overview
The laboratory processing of a drug test result includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial processes involved in integrating a sample into a laboratory system, such as ensuring the sample is appropriately sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.
Screening provides a preliminary assessment for drugs of abuse. Although Screening offers a cost-effective method to exclude drug use in most samples, any positive results require confirmation to be valid for legal use. Presumptive positives identified in Screening must undergo secondary confirmation.
For samples deemed presumptive positives during Screening, additional hair is extracted from the original specimen for the Extraction phase. Here, drug extraction occurs at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging methods.
Confirmation of positive screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed as necessary before confirmation. The complete laboratory sequence from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

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.
