Accredited Drug Testing offers comprehensive hair follicle drug screenings in Benton, Tennessee. If you're in need of a hair-based drug or alcohol exam, Accredited Drug Testing excels in this modality and boasts testing facilities in various cities across the nation capable of performing such evaluations. Typically, 1.5 to 2 inches of hair is required, sourced from the scalp or body. Options include assessments for drugs, alcohol/ETG, along with other tailored testing solutions.
Hair follicle testing has seen increased prevalence in recent times as a methodology for drug screenings. This testing method has become the preference for employers, judicial bodies, and substance abuse experts, surpassing traditional urine tests. Employers enforcing zero-tolerance policies, judicial systems, and probation services are key adopters. An advantage of hair tests is the extended detection window, often up to 90 days, with samples secured through observed procedures, minimizing the likelihood of falsification. However, for detecting recent drug consumption within a 5-day period, urine tests remain more precise.

Hair testing is now recognized as an effective means to uncover drug and alcohol consumption. Hair retains a long-term record of alcohol and other substances by embedding biomarkers within the strands' fibers. When obtained close to the scalp, hair can yield approximately a 3-month timeframe for detecting alcohol and other drugs. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch segment consisting of roughly 200 hair strands (comparable to a #2 pencil) nearest to the scalp will result in 100mg of hair, providing the optimal sample size for both screening and confirmation. For tests involving EtG, add-ons, and/or more than 10 panels, 150mg of the sample is advisable. It’s suggested to use a jeweler’s scale to weigh the specimen. Should scalp hair be lacking, a comparable quantity of body hair may be gathered. Head hair signifies scalp hair only, whereas body hair denotes all other hair forms (like facial, axillary, etc.).
Process Overview
The drug test result processing at the laboratory consists of four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary handling of a sample in a lab’s system. This step verifies that the sample was correctly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and fills in any missing data not covered by an electronic chain of custody system.
Screening performs an initial swift analysis for drugs of abuse. Although Screening offers a cost-effective way to exclude drug use in most samples, a positive result demands confirmation for legal admissibility. Samples testing presumptively positive during Screening require secondary validation.
Should a sample show presumptive positivity in Screening, additional hair is extracted from the original sample and prepared for Extraction. During this phase, drugs are isolated from the hair at significantly lower concentrations compared to other methods (like urine or oral fluid), rendering hair drug screening the most intricate methodology to execute.
Confirmation for any positive Screening outcome is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo washing before confirmation if necessary. The complete laboratory procedure, from Accessioning to Confirmation, is scrutinized per the CAP (College of American Pathologists) Hair directive and the accreditation standards of ISO / IEC 17025.
Advantages of hair drug testing:
Limitations:
Note: Despite being often labeled as "hair follicle tests", the examination focuses on the hair strand rather than the follicle beneath the scalp.

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.
