Tracking Michigan coronavirus (COVID-19) testing data
Here we are tracking the state of Michigan’s coronavirus (COVID-19) tests data.
The following charts show daily cumulative test totals, the percent of positives, daily positive test results, daily negative test results and the daily percent positive.
NOTE: Michigan updated testing data reporting on May 23, 2020. From the state:
"The change makes the data more accurate and relevant as the state continues to expand diagnostic testing to help slow and contain the spread of COVID-19. The update to the website separates out the results of two different types of tests – serology and diagnostic. Michigan – along with some other states – has not separated data for diagnostic and serology tests.
Data on serology testing – also known as antibody testing – is separated from the other testing numbers. Currently, serology testing can be used to help determine whether someone has ever had COVID-19, while traditional viral diagnostic tests determine if someone has active disease."
The updated data is included in the charts below:
