A new type of test may be more effective at determining whether someone already had coronavirus compared to widely-used antibody tests. New research from the manufacturer, Adaptive Biotechnologies, which is based in Seattle, found that the test was eight times better at detecting past COVID-19 infection than a commercially available antibody test. Of the 70 people who had had confirmed cases of coronavirus, the test, called T-Detect, correctly identified 97 percent of cases, only missing two of them. By comparison, a commercial antibody test called DiaSorin only correctly identified 77 percent of cases, missing 16 of them. This means the test is eight times more effective at determining whether or not someone was previously infected with COVID-19.
