Hair follicle tests have become a leading method in drug screening over recent years. Many employers, judicial systems, and Substance Abuse experts prefer hair testing to the traditional urine tests. Employers with zero-tolerance policies, legal bodies, and probation services often rely on hair follicle tests. One of the main advantages is the test's extended detection timeframe, reaching up to 90 days, making it nearly impossible to manipulate results. Nonetheless, urine tests remain superior for detecting recent drug use, particularly in the past 5 days.

Hair testing is recognized as an effective method for detecting drug and alcohol consumption. It offers an extended timeline of substance use by capturing biomarkers within the fiber of the growing hair. Hair gathered near the scalp can deliver an approximately 3-month detection span for detecting drugs and alcohol. It's easy to acquire, relatively tamper-resistant, and simple to transport.
A 1.5-inch segment containing around 200 hair strands (comparable to the thickness of a #2 pencil) taken from the scalp yields 100mg of hair, which is the optimal quantity for analysis and validation. For EtG, additional tests, and/or panels over 10, a specimen weight of 150mg is advised. Using a jeweler’s scale to measure is suggested. Should scalp hair be lacking, an equivalent batch of body hair may be used. Reference to head hair pertains solely to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The key steps in laboratory processing of drug test outcomes include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the phase where a sample is introduced into a laboratory’s system. This step ensures the sample was correctly sealed and sent, assigns a LAN (Laboratory Accessioning Number) at random, and completes any supplementary data input not available through an electronic chain of custody system.
Screening conducts a preliminary rapid assessment for drug presence. Although this is an efficient means to exclude drug use in most samples, any positive screening outcomes must be corroborated to be legally admissible. Samples deemed positive during Screening necessitate subsequent verification.
In the event of a presumptive positive during Screening, additional hair is obtained from the initial sample and readied for Extraction. Drugs are drawn from hair in extremely low concentrations compared to other methods (such as urine or oral fluid), making hair drug screening uniquely challenging.
Verification of any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with potential positive results undergo washing before confirmation, as necessary. The entire laboratory procedure from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair certification and in accordance with ISO / IEC 17025 standards.

Note: Commonly misnamed "hair follicle tests," the assessment evaluates the hair strand itself, not the follicle located beneath the scalp

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.
