Accredited Drug Testing offers complete hair follicle drug testing in Tusculum, Tennessee. Specializing in hair testing, our centers nationwide, including Tusculum, perform hair drug and alcohol tests. Typically requiring 1.5 to 2 inches of hair from the crown or body, these tests detect drugs, alcohol/ETG, and offer other customizable options.
Hair follicle tests have become a prevalent method for drug testing in recent years. Many employers, courts, and substance abuse professionals prefer this over standard urine testing. These tests are vital for employers enforcing zero-tolerance drug policies, courts, and those on probation. They offer a longer detection window of up to 90 days, involve observed collection, and are hard to manipulate. However, for recent drug use within the last five days, urine tests remain more accurate.

Hair analysis has emerged as a formidable method for identifying drug and alcohol consumption. Hair captures long-term evidence of alcohol and drugs by embedding biomarkers within the fibers of the hair as it grows. When taken from near the scalp, hair can reveal drug and alcohol use data for up to about three months. This method is uncomplicated to gather, fairly resistant to tampering, and straightforward to transport.
A sample measuring 1.5 inches of roughly 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp yields 100mg of hair, serving as the optimal sample for both initial screening and further confirmation. For EtG, extra tests, and/or panels exceeding 10, a sample of 150mg is recommended. It is advisable to measure the specimen with a jeweler's scale. Should scalp hair be unavailable, an equivalent amount of body hair can be used. When mentioning head hair, we refer solely to scalp hair. Body hair includes all other hair varieties (such as facial or axillary hair).
Process Overview
The drug test laboratory process consists of four central phases: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, a sample is first incorporated into a lab's system. This phase includes ensuring correct sample seal and shipment, assigning a Laboratory Accessioning Number (LAN) at random, and completing any extra information entry not facilitated by an electronic chain of custody system.
Screening offers an initial swift review for substances of abuse. While economical, a positive screen requires confirmation to be valid in judicial settings. Samples with presumptive positives need further confirmation.
For samples indicating presumptive positives during Screening, additional hair is extracted from the original batch and prepped for Extraction. In Extraction, drugs are retrieved from hair at substantially lower concentrations than seen with methods like urine or oral fluid analysis, showcasing the complexity of hair drug screening techniques.
Analyzing and confirming any positive results involve GC/MS, GC/MS/MS, or LC/MS/MS processes. Presumptive positive samples undergo washing before confirmation when necessary. The entire procedural series from Accessioning through Confirmation is scrutinized under the CAP's (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditations.

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.
