Important information about SARS-CoV-2 (COVID-19) antibody testing

Antibody tests are intended as aids in identifying individuals with an adaptive immune response to COVID-19, indicating recent or prior infection. It can be useful in providing evidence of an immune response over time and may benefit people at high-risk for being infected or for severe outcomes. Results are for the detection of SARS-CoV-2 antibodies.

IgG and IgM antibodies to SARS-CoV-2 are generally detectable in blood several days after initial infection, although the duration of time antibodies are present post-infection is not well characterized.

At this time, it is unknown for how long antibodies persist following infection and if the presence of antibodies confers protective immunity. Individuals may have detectable virus present for several weeks following seroconversion. Negative results do not preclude acute SARS-CoV-2 infection. If acute infection is suspected, molecular testing for SARS-CoV-2 is necessary. The tests should not be used to diagnose acute SARS-CoV-2 infection. False-positive results for the test may occur due to cross-reactivity from pre-existing antibodies or other possible causes.

The sensitivity of the IgM test early after infection is unknown. Due to the risk of false-positive results, confirmation of positive results should be considered using a second, different IgM assay or an IgG assay. Samples should only be tested for IgM from individuals with 15 days to 30 days post-symptom onset. SARS-CoV-2 antibody negative samples collected 15 days or more post-symptom onset should be reflexed to a test that detects and reports SARS-CoV-2 IgG.
