Point-of-care COVID antibody test is accurate, adaptable, low maintenanceDuke University researchers developed a point-of-care test (POCT) that can detect SARS-CoV-2 antibodies and four other coronaviruses with 100% accuracy, according to initial test results from a small cohort published in Science Advances late last week.
The test is called DA-D4 POCT, with DA standing for double-antigen and D4 being the assay platform recently developed to detect Ebola infections 1 day faster than typical polymerase chain reaction tests.The test uses a polymer brush coating that stops everything but the targeted molecules from attaching to the wet test slide, which can be zoned to delineate different biomarkers.
