CA, doesn't seem like the tests are very good? I work in a hospital. I was sick COVID like symptoms. Sent me home got tested the next Friday. Again on Sunday both came back negative. PCR nose swab test. Hospital gave go ahead come back to work Monday.
I got one day off. Turned out to be a sinus infection.
Which after going to the ED they were sure it was covid. Fever, sore throat, couldn't breath.
Didn't say here's an RX for xyz. I ended up going to the urgent care for Amoxicillin.
