Accredited Drug Testing provides comprehensive hair follicle drug assessments in Norris, Tennessee. If obtaining a hair drug or alcohol test is essential, our expertise in this area, with numerous centers Nationwide, ensures seamless testing. Typically, a sample of 1.5 to 2 inches of hair from the scalp or body is required. Our tests can examine drugs, alcohol/ETG, or other bespoke options tailored to your needs.
Over the years, hair follicle drug testing has become a preferred method for substance detection. Mandated by many employers, courts, and substance abuse experts, this method is increasingly replacing traditional urine tests, especially among zero-tolerance employers and in probation assessments. Its advantage lies in detecting drug use over a 90-day period, collected under observation, rendering tampering nearly impossible. However, for recent drug use (within 5 days), urine tests still hold the upper hand.

Hair analysis is now regarded as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drug intake by locking in biomarkers within the strands' fibers as they grow. Collected near the scalp, hair can indicate drug or alcohol use for up to roughly three months. Collection is straightforward, altering is challenging, and transportation is convenient.
A sample measuring 1.5 inches of roughly 200 hair strands (akin to a #2 pencil's thickness) near the scalp yields 100mg, the optimal quantity for testing and validation. For EtG, additional checks, and/or tests beyond ten panels, a quantity of 150mg is advisable. Utilizing a jeweler’s scale for weighing the sample is suggested. If scalp hair isn't available, a comparable quantity of body hair may be used. "Head hair" specifically denotes scalp hair, while "body hair" encompasses all other varieties (facial, axillary, etc.).
Process Overview
The primary stages in the laboratory analysis of a drug sample include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial entry of a sample into a laboratory's system, ensuring the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry not covered by an electronic chain of custody system.
Screening is the initial quick evaluation for drug presence. While Screening is efficient for excluding drug use in most samples, a positive result requires confirmation for court admissibility. Samples showing preliminary positive results in Screening need further verification.
If a sample shows presumptive positivity during Screening, additional hair is taken from the initial sample to prepare for Extraction. During Extraction, drugs are retrieved from hair in significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening exceptionally challenging.
Any positive screening outcome is validated via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity are laundered before confirmation if necessary. The complete lab process from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair guidelines and 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.

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.
