Scientists at the University of Florida have harnessed the power of artificial intelligence (AI) to enhance at-home diagnostic tests for diseases like hepatitis C and COVID-19. Their groundbreaking research has led to the development of a streamlined one-pot reaction test, named SPLENDID, which amplifies fragments of a virus’s genome to detect its presence. The test has demonstrated an impressive accuracy of 97% for detecting SARS-CoV-2 and 95% for the most prevalent strain of hepatitis C.
The innovative collaboration between AI technology, RT-LAMP, and CRISPR has paved the way for potential advancements in at-home testing for a wide range of diseases, extending beyond pregnancy and COVID-19. The University of Florida scientists aspire to create a home-based test that matches the reliability of lab-based tests. Their objective is to design a simple and affordable test that eliminates the need for expensive equipment, providing results in just 10 to 20 minutes.
To achieve these goals, the research team has focused on perfecting a one-pot reaction system, allowing the entire test to occur in a single small test tube. This system, based on RT-LAMP technology, can amplify specific portions of a virus’s genome and generate a visible signal upon virus detection. The interpretation of results can be as straightforward as identifying a color change or utilizing a compact device that detects alterations in the test tube.
While some at-home one-pot tests for COVID-19 have received emergency use authorization from the FDA, their relatively high false positive rates have hindered their reliability. In order to distinguish between false positives and true positives, the researchers have incorporated CRISPR technology. By leveraging the precise genetic targeting capabilities of CRISPR, the test only shows a positive result when the genetic sequence associated with the target virus is genuinely present.
However, a challenge arises from the temperature requirements of the RT-LAMP and CRISPR technologies, which differ by 50 degrees Fahrenheit. This discrepancy has made the tests significantly more complex, necessitating two separate reactions and rendering them impractical for at-home use. To bridge this gap, the team utilized AI tools to analyze a heat-tolerant CRISPR enzyme, originating from a thermophilic bacterium that thrives at 140 degrees Fahrenheit. Through AI-driven analysis, they identified four key modifications to the enzyme that allowed it to function optimally at 150 degrees Fahrenheit.
The culmination of these efforts led to the creation of the SPLENDID test, which the team validated using clinical samples from patients infected with hepatitis C or COVID-19. The test exhibited an accuracy of 97% for detecting SARS-CoV-2 and 95% for the most prevalent strain of hepatitis C. Although the test performed less effectively against other less common hepatitis C strains, the researchers are confident that simple adjustments to the test will swiftly improve its accuracy. The study detailing their findings was published on May 8, 2023, in the journal Cell Reports Medicine.
Supported by funding from the National Institute of Allergy and Infectious Diseases at the National Institutes of Health, the researchers aim to further refine the SPLENDID test, enhance its ability to differentiate between hepatitis C strains, and validate its efficacy in hospital settings. Their ultimate goal is to make at-home testing accessible to the general population, providing a convenient and reliable tool for early identification and treatment of viral infections like hepatitis C.
