This is revolutionary.
A new study has introduced a promising paper strip test designed to diagnose influenza swiftly and accurately, while also identifying specific strains responsible for infections. Published in the Journal of Molecular Diagnostics, the research highlights the test’s ability to distinguish between influenza A and B, the main types of seasonal flu, as well as more virulent strains such as H1N1 and H3N2.
The primary goal of this innovation is to create a cost-effective diagnostic tool that can be easily deployed in various settings, from clinics to field operations, without the need for advanced laboratory equipment. Cameron Myhrvold, co-senior researcher from Princeton University, emphasized the test’s potential to streamline outbreak responses and improve infection management globally, akin to the rapid antigen tests used for COVID-19.
The test utilizes genetically engineered enzymes to detect specific viral RNA sequences in samples, a technique initially developed for COVID-19 testing and variant identification, including Delta and Omicron. Starting in 2022, the technology was adapted to target influenza viruses, aiming to provide a rapid screening method that enhances clinical decision-making.
Ben Zhang, a co-lead researcher from Harvard Medical School, highlighted the practical advantages of the test, noting its capability to operate at room temperature and deliver results within approximately 90 minutes. The team is working towards further reducing the testing time to just 15 minutes, which would significantly enhance its usability and impact in real-time patient care.
Crucially, the test’s ability to distinguish between different flu strains is seen as pivotal for tailoring treatment strategies, particularly in identifying strains resistant to antiviral medications like oseltamivir (Tamiflu). Jon Arizti-Sanz, another co-lead researcher from the Broad Institute of Harvard and MIT, stressed the importance of this capability for both individual patient management and broader public health interventions.
Looking ahead, the researchers are focusing on expanding the test’s scope to include surveillance of avian and swine flu strains that pose potential threats of crossover into human populations. This ongoing development underscores a commitment to advancing diagnostic technologies that can address current and future challenges posed by infectious diseases effectively and efficiently.
