Weeks run from Monday to Sunday, and results are reported on the date the tests were collected (this is a change to how they were previously reported, made for clarity). Weekly results reflect the results to date for that week; for the current week, they may not capture a full week's results.

Any “positives” that are later determined to be false will be subsequently removed from the testing results on the dashboard as will any reconfirmed positives (i.e. member who receives a positive test result and then another positive test result less than 90 days from the first).

* Indeterminate test results are those that the Broad Institute was unable to process for a variety of reasons such as insufficient sample size. The Broad Institute indicated that up to 5 percent of results could return as indeterminate.
