Negative test results reported in our API and CSVs are calculated by subtracting Positive PCR tests (people) from Total PCR tests (specimens) in the absence of better data.
As of September 18, 2020, Kentucky's total test results are drawn from our
totalTestsViral field instead of calculated via positive+negative.
As of May 27, 2020, Kentucky reports antibody tests separately from PCR tests.
On May 23, 2020, Kentucky revised down the state's figure for Total tests.
