Accredited Drug Testing provides comprehensive hair follicle drug tests in Union City, Tennessee. If a hair drug or alcohol test is required, our specialty lies in hair testing, with centers across all cities nationwide capable of conducting these tests. Generally, 1.5 to 2 inches of hair from the crown or body hair may be used. Hair tests can detect drugs, alcohol/ETG, or other tailored testing specifics.
In recent times, hair follicle drug tests have become a preferred method for drug testing. Many employers, judicial systems, and substance abuse specialists demand hair drug tests over standard urine tests. Hair follicle tests are prevalent among employers with strict no-drug policies, the legal system, and those on probation. The main advantage lies in their extended detection period for substance use, which typically extends up to 90 days, while collection is under observation, rendering manipulation nearly impossible. Yet, for drug use screening within the last 5 days, urine tests remain the most effective.

Hair analysis has emerged as a potent method for identifying drug and alcohol consumption. Hair retains a prolonged record of substance intake by capturing biomarkers within the strands. When sourced near the scalp, hair can offer up to a 3-month detection period for substances. It is straightforward to collect, relatively tamper-resistant, and simple to transport.
A 1.5-inch section of approximately 200 hair strands (similar in thickness to a #2 pencil) nearest to the scalp yields 100mg, which is optimal for both preliminary and confirmatory analysis. For EtG, add-ons, and/or extensive panels above 10 panels, a 150mg sample is advisable. Utilizing a jeweler’s scale for measurement is recommended. In cases where scalp hair is unobtainable, a comparable amount of body hair is acceptable. “Head hair” specifically pertains to scalp hair, whereas “body hair” encompasses all other types (facial, axillary, etc.).
Process Overview
The drug testing laboratory procedure comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially processed into the lab system, which includes ensuring the sample was sealed and shipped correctly, allocating a unique LAN (Laboratory Accessioning Number), and inputting any further data absent in an electronic chain of custody setup.
Screening acts as a preliminary assessment for drugs. Though cost-efficient for excluding drug use in most samples, a screening positive must be confirmed to be valid in legal settings. Samples suspected to be positive in Screening necessitate a confirmatory test.
For samples presumed positive in Screening, additional hair is extracted from the original specimen for Extraction. Here, drugs are extracted from hair at lower concentrations compared to methods like urine or oral fluid testing, marking hair drug screening as the most complex methodology available.
Confirmation of a positive screen entails GC/MS, GC/MS/MS, or LC/MS/MS analysis. Any samples tentatively positive are washed before confirmation when required. The laboratory procedure from start to finish is audited under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.
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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations. As we embrace these advancements, we pave the way for a safer, healthier society, where drug testing and analysis serve as powerful tools in protecting public health and maintaining integrity in various sectors. The research presented in this special issue will undoubtedly shape the future of drug testing and analysis, fostering collaboration and inspiring further innovation in this crucial area of scientific inquiry.
