241 Million Coronavirus Diagnostic Tests Confirmed

The U.S. CDC reported over 241 million RT-PCR diagnostic tests, excluding antibody and antigen tests, have been performed to confirm if a person has a SARS-CoV-2 coronavirus infection. The state of California leads the USA with 27,096,271 coronavirus tests performed, followed by New York (22,583,186), Florida (16,865,245), and Texas (14,591,186).

Overall, the CDC's data indicates a COVID-19 infection positivity rate of 8.6%, as of December 30, 2020.

The CDC does not currently recommend using antibody testing as the sole basis for a diagnosis of acute infection. In certain situations, serologic assays may be used to support the clinical assessment of persons who present late in their illnesses when used in conjunction with viral detection tests.
