Disclaimer: Data are provisional and subject to change. When launched on May 8, 2020, the data presented on this page were aggregate data reported to CDC from state health departments and territorial jurisdictions and represented all laboratory tests by state. Currently, there are two types of tests available要iral tests (tests for current infection) and antibody tests (tests for past infection). These tests often have different uses, which can present challenges for interpretation. Although antibody tests only account for a small proportion of cumulative testing nationally at this time, it has recently become more widely available, and CDC is working to differentiate those tests from the viral tests. We will report this information, differentiated by test type in future updates to this website. States and CDC are rapidly moving to a more detailed reporting format, known technically as line level data (each line in the file is a single laboratory test), which will enable CDC to display viral test data and serologic test data separately on the COVID Data Tracker. Given that this map shows total tests by state, some states may have included antibody tests in recent submissions of their total test counts. At a minimum, the following states have excluded antibody tests in their reports to CDC and the totals above represent only viral testing: Arizona, California, Colorado, Idaho, Indiana, Iowa, Louisiana, Minnesota, New Mexico, New Jersey, New York, Utah, Vermont, Virginia, Washington. The number of states that have excluded antibody testing from their total test counts will continue to increase, and CDC will update this list to provide clarity.
Electronic laboratory reporting will speed reporting time. Data presented here might not represent the most current counts for the most recent 3 days due the time it takes to report testing information. The data may also not include results from all potential testing sites within the jurisdiction (e.g., non-laboratory or point of care test sites) and therefore reflect the majority, but not all, of COVID-19 testing being conducted in the United States. If a state did not report laboratory data for a specific day, or if data reported by states are incomplete, data presented reflect what is reported on the state health department website or laboratory testing data reported to the Department of Health and Human Services.
