I’m on day 7 of my symptoms for suspected Covid 19 and was wondering whether to have a private swab test. If I order it tomorrow it will come on day 9 of my symptoms. Will I still have the virus detectable? I only have a cough and slight sore throat now. It’s £250 so I don’t want to throw money down the drain if the virus won’t show even if I have had it. I’m keen to find out for sure as it will lower my anxiety about going to the supermarket when I need to that I’m not going to get sick as I will have immunity. Question is - will the test still be able to pick up Covid when I’m on day 9? I think the current feeling is that you stop being infectious at day 7 but I don’t know how sensitive the swab test is.
