Accredited Drug Testing offers comprehensive hair follicle drug testing services in Dyer, Tennessee. If a hair drug or alcohol test is needed, Accredited Drug Testing excels in hair testing. Nationwide, we have centers capable of conducting hair tests, requiring 1.5 to 2 inches of hair from the crown or body. Hair analysis can reveal drugs, alcohol/ETG, or other tailored testing options.
Recently, hair follicle drug testing has increasingly become a method of choice for drug tests. Employers, courts, and Substance Abuse professionals often prefer a hair drug test over the traditional urine test. Hair follicle drug tests appeal to employers with no-tolerance drug policies, courts, and those on probation. These tests offer a prolonged detection window for drug use, typically up to 90 days, incorporating an observed collection and are almost tamper-proof. Nevertheless, for recent drug use (within 5 days), urine tests remain the most precise.

Hair testing is now recognized as an effective means to identify drug and alcohol consumption. Hair retains a comprehensive record of alcohol and drug usage by embedding biomarkers within the fibers of the expanding hair strand. When collected near the scalp, hair samples can offer a detection timeframe of up to approximately three months for intoxicants. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.
A 1.5-inch sample comprising roughly 200 hair strands (akin to the thickness of a #2 pencil) taken from the scalp region yields 100mg, which is optimal for screening and confirmation. For EtG assessments, additional screenings, and/or tests exceeding 10 panels, a sample of 150mg is recommended. It is advised to measure the specimen's weight using a jeweler’s scale. If scalp hair cannot be obtained, a proportional amount of body hair may be used. When mentioning head hair, it implies only scalp hair. Body hair encompasses other varieties (facial, axillary, etc.).
Process Overview
The drug testing laboratory processes involve four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into the laboratory infrastructure. This process includes ensuring the sample was appropriately sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing supplementary data entries absent from an electronic chain of custody system.
Screening entails a preliminary rapid assessment for drug presence. Despite Screening's cost-effectiveness in excluding drug presence in most samples, a confirmed positive screen is essential for legal admissibility. Samples showing a presumptive positive during Screening necessitate subsequent confirmation.
For samples that test presumptively positive during the Screening phase, additional hair is extracted from the initial sample for the Extraction phase. In this phase, drugs are extracted at much lower concentrations from hair than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.
Confirmation of any positive screening results occurs through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing before confirmation as necessary. The entire laboratory cycle, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and accreditation under ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: While commonly known as "hair follicle tests", the analysis targets the hair strand and not 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.
