Hair testing has emerged as an effective instrument for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and drug intake by embedding biomarkers within the strands as they grow. When taken from near the scalp, hair can offer a detection window for alcohol and drugs lasting up to around three months. Hair collection is straightforward, challenging to tamper with, and convenient to send.
A sample measuring 1.5 inches with about 200 hair strands (roughly the width of a #2 pencil) nearest to the scalp yields 100mg, which is ideal for both screening and confirmation. In cases involving EtG, additional tests, or tests exceeding 10 panels, 150mg of hair is advised. It's suggested to weigh the sample using a jeweler's scale. If scalp hair is not accessible, a similar quantity of body hair may be used. "Head hair" specifically refers to scalp hair only; "body hair" encompasses all other hair types (such as facial or axillary hair).
Process Overview
The laboratory procedures for processing a drug test result consist of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the sample's preliminary processing within a laboratory's system. This step involves confirming the secure sealing and correct shipping of the sample, generating a unique LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent from an electronic chain of custody system.
Screening is a preliminary, expedited check for illicit substances. While Screening is an economical measure for excluding drug use across most samples, a positive result requires confirmation for legal admissibility. All specimens that test presumptively positive in Screening necessitate a confirmatory follow-up.
If a specimen is deemed presumptively positive during Screening, additional hair is taken from the original sample and prepared for Extraction. This phase entails isolating drugs from hair at a lower concentration compared to other techniques (e.g., urine or oral fluids), presenting hair drug screening as the most intricate method to execute.
Confirmation of any positive screen result is executed using GC/MS, GC/MS/MS, or LC/MS/MS technologies. Any samples with presumptive positive results undergo washing prior to Confirmation when necessary. The entire laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation 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.
