Accredited Drug Testing provides comprehensive hair follicle drug screening in Tabernacle, Tennessee. If you require a hair or alcohol test, we specialize in hair testing, with facilities in every city nationwide equipped to conduct such tests. Generally, hair length from 1.5 to 2 inches on the head is needed, but body hair can also be used. Hair tests can assess drugs, alcohol/ETG, or other specific hair analyses.
Over recent years, hair follicle drug tests have increasingly become part of the drug testing process. Many employers, judicial systems, and Addiction Treatment experts prefer hair tests over standard urine tests. Hair follicle exams are chosen by employers who enforce strict no-drug policies, courts, and individuals under probation. The key advantage of a hair test is its extended detection window, typically up to 90 days, collected through an observed procedure, making it very difficult to tamper with. However, for usage detection within the past 5 days, urine tests maintain higher accuracy.

Recognized as a significant asset in identifying drug and alcohol consumption, hair testing offers a comprehensive history by embedding biomarkers within the hair strand's fibers as it grows. Hair samples, if taken near the scalp, can reveal alcohol and drug usage over a span of up to roughly three months. The collection process for hair is straightforward, challenging to tamper with, and effortless to transport.
A 1.5-inch sample comprising about 200 hair strands (akin to the width of a #2 pencil) taken from close to the scalp provides 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, further evaluations, and/or testing beyond 10 panels, a 150mg sample is advisable. It's suggested to measure the sample using a jeweler's scale. If scalp hair cannot be obtained, a similar quantity of body hair can be used. This mention of head hair specifically pertains to scalp hair. Conversely, body hair encompasses other types like facial and axillary hair, among others.
Process Overview
The primary phases in processing a drug test result in a lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample within the laboratory's system. This step involves ensuring that the sample was properly sealed and delivered, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not captured by an electronic chain of custody system.
Screening serves as an initial rapid review for substance misuse. While Screening provides a cost-efficient means to dismiss drug usage for most specimens, any positive findings need further confirmation to be considered valid in legal proceedings. Samples that yield a presumptive positive during Screening necessitate an additional confirmation step.
For samples that indicate a potential positive during the Screening phase, additional hair is extracted from the original sample to undergo the Extraction process. In Extraction, drugs are obtained from hair at significantly lower concentrations compared to other methods, like urine or oral fluid, which makes hair drug screening especially challenging to execute.
Confirmation of any positive result identified during Screening employs techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples with presumptive positive results are cleaned as required. The complete lab process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.

Note: Often termed as "hair follicle tests", the analysis examines the hair strand and not the follicle beneath the scalp.

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.
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.
