Lately, hair follicle drug tests are more popular for drug screening. Employers, legal systems, and professionals prefer it over urine tests. Companies with strict drug policies use hair testing, as well as courts and probation services. The advantage is an extended detection time, up to 90 days, performed under supervision, and nearly tamper-proof. However, for recent drug use within 5 days, urine tests are more precise.

Hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug usage by embedding biomarkers within the fibers of the growing strand. When obtained near the scalp, hair can offer approximately a 3-month detection window for substances. Collecting hair is straightforward, comparatively hard to tamper, and convenient to ship.
A 1.5-inch sample consisting of approximately 200 hair strands (comparable to the width of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, additional panels, or tests that exceed 10 panels, 150mg of the specimen is suggested. We advise using a jeweler’s scale to weigh the specimen. If scalp hair is not available, a similar quantity of body hair can be used. When mentioning head hair, we specify scalp hair exclusively. Body hair pertains to all other hair types (facial, axillary, etc.).
Process Overview
The drug test result processing in a laboratory involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary processing step for a sample within a lab's system. This step comprises validating that the sample was securely sealed and correctly dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry not covered by an electronic chain of custody framework.
Screening consists of a swift initial assessment for drug presence. Although Screening is a cost-efficient technique to exclude drug usage for most samples, a positive screening outcome mandates confirmation for legal admissibility. Any samples that are presumptively positive in Screening necessitate secondary confirmation.
If Screening suggests a positive result, additional hair is extracted from the initial specimen and made ready for Extraction. In this stage, drugs are isolated from hair at significantly lower concentrations compared to other methodologies (e.g., urine or oral fluid), underscoring why hair drug screening is the most challenging method to conduct.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation as required. The comprehensive laboratory procedure, spanning from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair standards and in accordance with ISO / IEC 17025 accreditation criteria.

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.
