While several serological tests are currently available, with the emergence of more transmissible and virulent variants of concern (VOCs) there is an urgent need for a test that can quickly measure nAbs against all VOCs simultaneously.
Scientist at Duke University have developed a simple and rapid serological test that could tell doctors how protected a patient is from new variants and those currently circulating in a community and which monoclonal antibodies to use to treat a COVID-19 patient. The new test uses a non-stick polymer brush coating (POEGMA) that stops anything but the desired biomarkers from attaching to a wet test slide.
