Accredited Drug Testing offers comprehensive hair follicle drug tests in Viola, Tennessee. Should you require a hair-based drug or alcohol analysis, our expertise lies in specialized hair testing. We operate testing sites in cities across the nation ready to perform these tests. For most cases, 1.5 to 2 inches of hair from your head or body suffices. Hair tests are capable of detecting drugs, alcohol/ETG, or other tailored testing options.
In recent occasions, drug screening methods increasingly favor hair follicle drug tests. Various employers, judicial systems, and substance abuse experts now prefer hair drug examinations over conventional urine tests. With a strict no-drug policy, employers, courts, and those on probation consider hair follicle tests ideal due to their extended drug use detection, covering up to 90 days. The collection process is observed and nearly immune to tampering. Yet, for drug usage within the last 5 days, urine tests remain superior.

Hair analysis has emerged as a formidable instrument for identifying drug and alcohol consumption. Hair offers an enduring record of alcohol and drug use by encapsulating biomarkers within the fibers of a growing hair strand. When positioned near the scalp, a hair sample can reveal a detection period of up to roughly 90 days for alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and conveniently transported.
A 1.5-inch segment of approximately 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample for both screening and confirmation. For EtG, additional panels, and tests exceeding 10 panels, a sample size of 150mg is advised. It is suggested to measure the sample using a jeweler’s scale. If scalp hair is not present, an equivalent amount of body hair can be collected. References to head hair pertain solely to scalp hair. Body hair encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into a lab’s system. This step involves confirming proper sealing and shipment of the sample, generating a unique LAN (Laboratory Accessioning Number), and finalizing any supplemental data entry absent from an e-chain of custody system.
Screening performs a preliminary rapid assessment for drug abuse. Although Screening provides a cost-efficient means to rule out drug usage on most samples, any positive screen mandates confirmation for legal acceptance. Samples rendering positive results in Screening require a subsequent confirmation.
Upon a presumptive positive result during the Screening phase, additional hair is sourced from the original specimen for Extraction preparation. In this phase, drugs are extracted from hair at a much lower concentration than other techniques (e.g., urine or oral fluid), underscoring the complexity of hair drug analysis.
Verification of positive screening outcomes is executed by GC/MS, GC/MS/MS or LC/MS/MS. Every sample with presumptive positive results undergoes a cleansing process prior to confirmation as warranted. The entire laboratory workflow from Accessioning to Confirmation undergoes evaluation in adherence with CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.

Limitations:
Note: Although commonly termed "hair follicle tests", the evaluation examines the hair strand, rather than 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. 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.
