Accredited Drug Testing provides comprehensive hair follicle drug testing services in Crossville, Tennessee. If you're in need of a hair drug or alcohol test, Accredited Drug Testing is adept at hair testing, with testing centers across all cities nationwide that can conduct a hair test. A minimum of 1.5 to 2 inches of hair on your head's crown or body is required in most cases. Hair tests can assess drugs, alcohol/ETG, or other custom hair testing options.
In recent years, the method for drug testing increasingly involves a hair follicle drug test. Many employers, courts, and Substance Abuse professionals now request a hair drug test over the traditional urine test. Hair follicle drug tests are favored by employers maintaining zero-tolerance drug use policies, courts, and those on probation. The chief advantage of a hair drug test includes a prolonged detection window, typically reaching up to 90 days, gathered in an observed manner, making it nearly foolproof. However, for detecting drug use within the last five days, urine tests remain the most precise.

Hair assessments have emerged as a robust means for identifying substance and alcohol consumption. Hair offers a long-duration record of alcohol and drug use by embedding biomarkers in the fibers of the growing strand. When gathered near the scalp, it can present an approximate 3-month window of detection for alcohol and drugs. Hair is straightforward to gather, somewhat resistant to alteration, and simple to transport.
A 1.5-inch segment containing approximately 200 hairs (roughly the width of a #2 pencil) nearest to the scalp yields 100mg of hair, which is considered the ideal quantity for screening and confirmation. For EtG, add-ons, and/or tests beyond ten panels, 150mg of the sample is suggested. We advise weighing the sample using a jeweler’s scale. If scalp hair is not available, an equivalent volume of body hair can be gathered. In the context of head hair, our reference is specifically to scalp hair. All other hair types (facial, axillary, etc.) are referred to as body hair.
Process Overview
The four fundamental stages in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the initial integration of a sample into a lab’s protocol. This encompasses verifying proper sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and executing any supplementary data entry not covered by an electronic chain of custody process.
Screening involves an initial rapid check for illicit substances. While Screening is a cost-efficient approach to dismiss drug presence in the majority of samples, a positive screening requires confirmation to be valid in legal settings. Any samples that appear presumptively positive during Screening necessitate a secondary verification.
Should a sample reflect a presumptive positive in the Screening phase, additional hair is drawn from the initial sample and prepped for Extraction. This stage involves extracting drugs from hair at a concentration much lower than other techniques (e.g., urine or oral fluid), which is why hair drug testing is regarded as the most challenging methodology to administer.
Confirmation of any positive screening results is undertaken through GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positive samples undergo cleansing before confirmation as necessary. The comprehensive laboratory progression from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair classification and compliance with ISO/IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: While often referred to as "hair follicle tests", the testing procedure actually examines 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. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
