About 3% to 4% of people with negative antibody tests got COVID-19 in each time period. Also called a molecular test, this COVID-19 test detects genetic material of the virus using a lab technique called polymerase chain reaction (PCR). An antibody test is a blood test that looks for immune molecules, or antibodies, specifically targeted to fighting SARS-CoV-2, the virus that causes the COVID-19 illness. If you receive an invalid/rejected test result, you will be required to retest within 24-48 hours of your original test date. First Saliva Test for COVID-19 Approved for Emergency Use by FDA.

According to Caesar, he and his family members were among those who attended one of the county's COVID-19 virus test events between Nov. 2 and Nov. 9. Two types of viral tests can be used: nucleic acid amplification tests (NAATs) and antigen tests. Inconclusive test results occur with tests for any virus. The timing aspect seems to be particularly important here. However, the accuracy of a test can vary depending on when your sample is taken during the course of your illness. These are tests that proved inconclusive, either because the sample wasn't taken correctly or because of some other issue involving the lab. 1 0 obj If your PCR or antigen test is inconclusive or indeterminate for COVID-19, it means that a small amount of viral DNA was identified but it was not enough to test positive.
