Researchers have demonstrated a tablet-sized device that can reliably detect multiple COVID-19 antibodies and biomarkers simultaneously. Initial results show the test can distinguish between antibodies produced in response to SARS-CoV-2 and four other coronaviruses with 100-percent accuracy. The researchers are now working to see if the easy-to-use, energy-independent, point-of-care device can be used to predict the severity of a COVID-19 infection or a person's immunity against variants of the virus.
