A rapid antibody test has been developed that does not require blood draws and can provide results in just 10 minutes. This test uses advanced wearable biosensors to detect antibodies associated with viral infections, including those caused by COVID-19 and influenza. The sensors are significantly more sensitive than standard tests.
Professor Alexander Star explains that these sensors work by analyzing interstitial fluid, the liquid found between cells, which contains antibodies similar to those in blood. This method allows for quicker diagnostics compared to conventional lab-based tests that collect blood samples and take longer for results.
Furthermore, the technology could revolutionize monitoring for chronic conditions, offering customized treatment based on real-time antibody levels. Researchers are exploring ways to combine these sensors with painless microneedle patches to facilitate easy testing.
