In Jellico, Tennessee, Accredited Drug Testing offers comprehensive hair follicle screening services. For those needing drug or alcohol hair tests, our expertise is unmatched, with centers across all major cities nationwide. A hair sample of 1.5 to 2 inches is generally required. Hair analysis can identify various drugs, alcohol/ETG, or other specialized options.
The hair follicle test is increasingly favored in recent years for drug detection. Employers, legal systems, and addiction specialists often choose this method over traditional urine analysis. Particularly useful for zero-tolerance workplaces and legal mandates, hair tests showcase a superior detection window of up to 90 days. They're collected under observation, making them highly tamper-proof. However, urine tests remain the benchmark for identifying very recent drug use, within the past 5 days.

Hair testing is increasingly viewed as a robust method for identifying drug and alcohol use. Hair records a comprehensive history of substance intake by capturing biomarkers within its fibers. Collected near the scalp, hair can reveal substance use up to a roughly 3-month timeframe. The process of collecting hair is straightforward, relatively resistant to tampering, and convenient for shipping.
A 1.5-inch section of roughly 200 hair strands (comparable to a #2 pencil's thickness) nearest to the scalp will provide 100mg of hair, which is optimal for testing and verification. For EtG, add-ons, or analyses exceeding 10 panels, 150mg of the sample is advised. It's preferable to measure the sample's weight using a jeweler’s scale. If scalp hair isn’t available, an equivalent volume of body hair is acceptable. When we mention head hair, we refer solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial incorporation of a sample into a lab's system. This step includes confirming the sample's proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry that isn't covered by an electronic chain of custody system.
Screening constitutes a preliminary rapid evaluation for substances of abuse. While Screening is a cost-effective strategy for excluding drug use on the majority of samples, a positive result necessitates confirmation to be permissible in legal contexts. Any samples returning a presumptively positive result in Screening require a subsequent confirmation.
Upon returning a presumptive positive in the Screening phase, extra hair is extracted from the original sample, preparing it for Extraction. This phase involves retrieving drugs from hair at significantly lower concentrations compared to alternative methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.
Confirmation of any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo a washing process before confirmation if necessary. The full laboratory procedure, from Accessioning through Confirmation, is reviewed under the CAP (College of American Pathologists) Hair designation in addition to compliance 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.
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.
