Accredited Drug Testing provides comprehensive hair follicle drug screenings, available in Limestone, Tennessee. For those in need of drug or alcohol testing utilizing hair samples, Accredited Drug Testing is a leader in this field and operates centers throughout the nation, where hair tests are conducted. Generally, 1.5 to 2 inches of head hair or body hair can be used. Our hair tests offer options to detect drugs, alcohol/ETG, and customizable testing solutions.
Recently, hair follicle drug testing has become more common in drug detection practices. Employers, legal systems, and substance abuse experts are increasingly opting for hair drug tests over traditional urine samples. Utilized by organizations with zero drug tolerance, courts, and individuals on probation, hair follicle tests offer a longer detection period, typically up to 90 days, ensuring a reliable, tamper-resistant method. However, urine tests remain optimal for identifying recent drug use within 5 days.

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.
Utilizing hair testing has emerged as a significant method for identifying the consumption of drugs and alcohol. Hair acts as an historical record of alcohol and drug usage by encasing biomarkers within the strands as they grow. When sampled near the scalp, hair can offer a detection timeframe of up to three months for alcohol and various drugs. It is straightforward to collect, relatively resistant to tampering, and simple to transport.
A hair sample measuring 1.5 inches and comprising roughly 200 strands (about the thickness of a #2 pencil) nearest to the scalp will provide 100mg of hair, which is ideal for testing and verification. For EtG, additional tests, and/or those spanning more than 10 panels, 150mg of hair is advised. Using a jeweler’s scale is recommended for weighing the specimen. In instances where scalp hair is absent, the equivalent quantity of body hair can be used. When discussing head hair, we mean scalp hair solely. Body hair refers to all other types of hair (e.g., facial, axillary).
Process Overview
The method of assessing a drug test result in the lab involves four principal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase, encompassing entering a sample into the laboratory's records. This process checks that the sample was sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and concludes any other data entry not captured by an electronic custody chain system.
Screening entails an initial rapid examination for drug abuse. Although Screening is a budget-friendly approach to dismiss drug use in most samples, testing positive necessitates confirmation for legal admissibility. Any samples showing presumptive positive results during Screening must undergo a confirmatory test.
In cases where a sample tests presumptive positive during the Screening phase, additional hair is extracted from the initial sample in preparation for Extraction. During this process, drugs are derived from the hair at much more diluted concentrations than other methods (e.g., urine or oral fluid), making hair drug testing one of the most challenging techniques to execute.
Confirmation of any positive results from the screening phase is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptively positive are cleansed prior to confirmation where needed. The entire lab procedure from Accessioning through Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

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.

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.
