Laboratory testing for SARS-CoV-2 includes methods that detect the presence of virus and those that detect antibodies produced in response to infection.
As of 21 March 2020, the CDC recommends RT-PCR for initial screening. The presence of viruses is generally confirmed by RT-PCR, which detects the coronavirus' RNA. This test detects only the RNA of the SARS-CoV-2 and is used to confirm very recent or active infections.
Detection of antibodies (serology) can be used both for diagnosis and population surveillance. Antibody tests show how many people have had the disease, including those whose symptoms were minor or who were asymptomatic. An accurate mortality rate of the disease and the level of herd immunity in the population can be determined from the results of this test.
Due to limited testing, as of March 2020 no countries had reliable data on the prevalence of the virus in their population. By 23 March, no country had tested more than 3% of their population, and there are variations in how much testing has been done across countries. This variability is also likely to be affecting reported case fatality rates, which have probably been over-estimated in many countries, due to sampling bias.
