New York State – Tests Administered versus Percent Tested Positive



Highlights...

1. Between 04/01 and 04/29, out of the 679,700 (average 23,438/day) coronavirus tests that the state of New York performed, 220,660 (average 7,609/day) turned out to be positive, meaning roughly 33% were tested positive. 

2. Considering that the tests were restricted to the symptomatic cases in New York, the positive rate was understandably high -- much higher than the national average of 17.25%.

3. However, when the daily data were split into two competing halves -- 04/01 to 04/15 vs. 04/16 to 04/29 -- the average rates (of those tested positive) were significantly different: the first half showing at 42% while the ongoing second half at 23.4%, although the test totals were fairly close. 

4. This large difference leads us to believe that NYS, of late, has relaxed the testing requirements from "acute" to "probable" cases leading to the lower rates. The data table depicts how the daily % positive has steadily declined from 48% to under 20% in recent days.

5. New York needs to do a more consistent job in using its testing resources. The daily totals are showing a random dance pattern, ranging between 15K and 28K (outliers excluded), proving that they can easily achieve at least 25K daily with the existing resources.
