From March 18th to 22nd positive test results were being reported daily from some labs without the number of tests administered. The cumulative total number of tests conducted by these labs were reported on March 23rd.

2 thoughts on “Massachusetts COVID-19 Test Results. March-April 8th 2020”
On the March 22nd report from the state it mentions that the number of tests includes patients that have been re-tested. Do you know if the subsequent test statistics include re-tests? If re-tests are included then the ratio of positive results would be impacted.
Looking at past reports, March 16th is the first day with the notion that the results include individuals who were retested and March 22nd is the last. I think after the 22nd we can assume that the totals include those that are retested. One of the issues with MA DPH reports is that their reporting changes over time. Yesterday April 8th is the first day when they started reporting Race/Ethnicity. You’ve got me wondering about how many are retested and what that cohort looks like. In addition to outside patients, medical workers, in particular, come to mind.
