re: Medical professionals: How accurate are these Covid -19 test

Well, they are certainly better than the first tests the CDC rolled out.

Well looks like my concerns were warranted.

Covid 19 year May miss as many as 1/3 of positive people

China’s sensitivity was 63%

They think the tests we are using in Minnesota have a sensitivity between 60 and 70%. That means the false negative is between 30 and 40% in Minnesota.

I don’t know about Louisiana though

Why did they buy them from China?

When I read reports on lower sensitivity of US test it's usually people using Chinese data and included their own beliefs that people testing negative had to have had it. There is not a lot of objective proof included for US tests (admittedly it would have been tested more if not spreading so fast). The doctor of the healthcare worker from NO who died was so certain they had original negative's sample rested and then sent of another sample to a university and both came back negative making it 3 negative results across 2 labs. I still think doctor didn't believe it.

Right now many in US are testing most likely to have it and moderately symptomatic or preexisting risks. NJ keeps coming up with over 50% positive rates over past 5 days. NY is high, California is high but they also don't always include updates to negative results or test result totals. Michigan is high for same reason (haven't updated negative or test numbers for 6 days), and something with Oklahoma like they are very restrictive with their testing. I was just looking at these recently.

MN's rate is fairly low, but it seems consistent in daily results and with a good amount of tests done per capita.
