Dear Covid expert, My mother is 53 years old and she does not have any pre existing disease. 10 days back she has started symptoms like fever, headche, body pain and weakness. Yet fever is up and down. She was in contact with covid 19 positive. Today we did her antigen test and she found negative but still we are doing RT PCR test. So what is sign of negative antigen test? Is it she in recovery mode? Or else What i shall do in case RT PCR will still positive? Pl suggest.
