Accredited Drug Testing provides comprehensive hair follicle drug testing services in Greeneville, Tennessee. For those in need of a hair drug or alcohol analysis, we have nationwide testing centers ready to conduct a hair test. Typically, you will need 1.5 to 2 inches of hair from the crown of your head or body. Hair tests can determine drug and alcohol/ETG use, along with other tailored testing solutions.
Over the years, hair follicle drug testing has become more prevalent for detecting drug use. Many employers, courts, and substance abuse professionals now prefer this method over traditional urine testing. Hair follicle tests serve employers with zero-tolerance policies, courts, and probation clients, offering a longer detection window of up to 90 days, conducted under observed conditions, making it nearly tamper-proof. However, urine tests still lead in detecting very recent (past 5 days) drug usage.

When you're searching for hair drug testing near me or hair drug testing locations, we provide a simple and convenient process to find a drug and alcohol testing location near you that is certified to provide all of your drug and alcohol testing needs.
The recognition of hair testing as a robust method for detecting drug and alcohol consumption has gained prominence. Hair retains biomarkers within its fibers, providing a comprehensive history of substance use over a prolonged period. When collected near the scalp, hair can yield a detection window of approximately three months for substances like alcohol and drugs. Collection is straightforward, challenging to manipulate, and easily shippable.
Obtaining a 1.5-inch segment containing roughly 200 strands of hair (comparable to the thickness of a #2 pencil) closest to the scalp equates to 100mg, which is the optimally required amount for both screening and confirmation. For EtG, additional analyses, or tests exceeding 10 panels, a 150mg specimen is advisable. It's suggested to measure the sample using a jeweler's scale. When scalp hair is absent, a comparable quantity of body hair might be gathered. By head hair, we mean exclusively scalp hair. Body hair encompasses all other types (e.g., facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial handling of a sample within the laboratory's infrastructure. This stage verifies the proper sealing and shipment of the sample, assigns a unique LAN (Laboratory Accessioning Number), and fulfills any additional data entries absent from an electronic chain of custody system.
Screening offers a preliminary, efficient check for drug abuse. Though a cost-effective means to dismiss drug use in most samples, a positive screen mandates confirmation for legal admissibility. Samples yielding a presumptive positive in this phase necessitate further confirmation.
Should a sample be deemed presumptively positive during Screening, additional hair is extracted from the original specimen for the Extraction phase. This phase retrieves drugs from hair at significantly lower concentrations than methodologies like urine or oral fluid, rendering hair drug screening notably complex.
Confirmation of any positive screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing as required before confirmation. The full laboratory procedure, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Often labeled as "hair follicle tests," the analysis is conducted on the hair strand, not the follicle 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.
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.
