How Do the COVID-19 Coronavirus Tests Work?

Tests may use two methods to detect SARS-CoV-2 virus that causes COVID-19. Genomic or molecular detection confirms the presence of viral DNA. The immunoglobulin or serology tests can tell whether or not you have been exposed to coronavirus, but not whether you are currently infected. Both tests administered in tandem can give you your complete COVID-19 infection status.How accurate are the rapid coronavirus tests?Apr 24, 2020(WTNH) Concerns are being raised about the accuracy of those quick 15-minute Abbott Labs COVID-19 tests being used in the state.

However, influenza virus testing can inform clinical management when the results may influence clinical decisions such as whether to initiate antiviral treatment, perform other diagnostic testing, or to implement infection prevention and control measures fSee more on cdc.govPublished These tests can provide results within approximately 10-15 minutes but are not as accurate as other flu tests. Therefore, you could still have flu, even though your rapid test result is negative. Other flu tests are called rapid molecular assays that detect genetic material of the virus.RT-PCR vs Rapid Test Comparing two test methodsMeanwhile, rapid test kits can produce near-instant results at the cost of accuracy.
