Hair testing is recognized as an effective means for spotting drug and alcohol usage. Hair captures a prolonged history of substance use by securing biomarkers within the expanding hair strand. When procured near the scalp, hair offers about a 3-month window for detecting drugs and alcohol. Collecting hair is straightforward, hard to tamper with, and convenient for shipping.
A hair sample of 1.5 inches containing approximately 200 strands (roughly the thickness of a #2 pencil) near the scalp will yield 100mg, the optimal amount for both screening and confirmation. For EtG, supplementary tests, and/or panels exceeding 10, 150mg is advised. It's best to use a jeweler's scale for weighing. If scalp hair isn't obtainable, a similar amount of body hair can be used. "Head hair" exclusively indicates scalp hair, while "body hair" includes all other hair varieties (e.g., facial, axillary).
Process Overview
The core steps in a lab’s drug test result processing include Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, a sample is initially processed within a laboratory’s framework. This incorporates confirming the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and finalizing any data not supplied by an electronic chain of custody.
Screening is an initial swift check for substances of abuse. Although cost-effective for excluding drug usage in most samples, a positive Screening requires confirmation to be plausible in court. Samples suggesting positivity in Screening mandate secondary confirmation.
Should a sample reflect positive from Screening, additional hair is extracted from the original sample for Extraction. This phase involves extracting drugs from hair at a considerably lower concentration than alternative methodologies (such as urine or oral fluid), making hair drug screening notably challenging.
Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Samples reflecting presumptive positivity are washed pre-confirmation as needed. The lab process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair classification and the accreditation 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.
