Doctor at UTHSC says COVID-19 tests can give false-negative results

[link:https://www.wmcactionnews5.com/2020/03/31/doctor-uthsc-says-covid-tests-can-give-false-negative-results/|

If I go get a test with someone who just started to get sick and so they’re infected but they don’t have much virus in them maybe it’s negative, but maybe if I test them three days later, it’s going to be positive because there’s a lot more virus in them at that point,” said McCullers.

McCullers says, unlike other respiratory illnesses COVID-19 patients tend to get worse by day 5 or 6 rather than improving. He also says even if you suspect you got a false negative there really isn’t any reason to be re-tested unless you end up in the hospital.

But you may want to quarantine yourself away from others while you’re not feeling well just to be on the safe side.

I wondered about this...

There's a 40% false negative rate with the CDC/FDA Covid-19 test. That's atrocious. SunSeeker Mar 2020 #3

Also, the Govt., including the CDC and military, is hiding the real numbers. I do not trust them anymore. They blew it with me. When we get Dems in charge I will possibly trust them again (not the military though).

of 40% came from. Unless it's Ross Douthat's "five out of eight cases were detected" - which seems a tiny sample, too small to pay attention to. It also doesn't say what the other, lower estimates are.

so one negative test does not rule out having corona virus
