I'm really worried about my COVID results. My wife tested positive but then negative after 10 days of quarantine. Ive been having a cold and a nose blockage for a bit, and my RTPCR just came back positive with a CT value of 33, but I don't feel any symptoms now. Do you think I need to redo the test soon, and how much longer should I stay in quarantine? I'm kind of anxious about what to do next.
