Portable serological assay detects SARS-CoV-2 antibodies with 100% accuracy in preliminary study

Written by Campbell Brooks

Researchers have developed an energy-independent, user-friendly device that can detect antibodies for multiple SARS-CoV-2 viral antigens in 60 minutes utilizing a single drop of blood. There is potential for application in population immunity studies as well as to track COVID-19 disease progression in individuals in low-resource settings. PCR tests for COVID-19 detect viral nucleic acids and are therefore extremely good at diagnosing current infection. However, it cannot give information on past infections or the patient’s immune response to the infection. This information is important for understanding COVID-19 disease progression and providing clinical prognoses. In a study published in Science Advances,...
