Covid changed even Influenza testing. Yesterday I went to the doctor here in Korea because I was feeling sick for over 3 days already and they asked if I want a test. I didn’t quite understand for what and thought it’s necessary so I said yes. It was the same as for Covid, they tickle your brain with a stick through your nose. After 5 minutes the test came back negative, I don’t have Influenza. They charged me $28, I guess most of it was for the test itself, the rest should have been covered by my insurance.
The flu test (at least here in the US) has been the brain tickler since at least 2017
