Nov 11, 2020 · Abbott offers separate antibody tests to detects the IgG and IgM antibodies. To understand a test’s accuracy, scientists look at sensitivity and specificity. In medical and scientific language, the Abbott IgG antibody test has 99.63% specificity and 100% sensitivity at the time of detecting antibodies 14 days or greater, post symptom onset.
May 18, 2020 · COVID-19 antibody tests look for evidence of past exposure to the SARS-CoV-2 virus, not an active infection. Antibody tests rely on blood samples. A venous blood draw tends to be more accurate, but a finger-stick test yields quicker results. Most tests can’t detect antibodies until 11 to 18 days after symptom onset or virus exposure.
Abbott labs' coronavirus antibody test achieves ‘high performance’ in study (May 8, 2020) Bruce Japsen / Forbes Study suggests Abbott COVID-19 antibody test highly likely to give correct results
Jun 11, 2020 · In less than 10 minutes you can have a COVID-19 antibody test at the testing location and can expect your results within 24- 48 hours.
