My father tested COVID 19 positive on 26 July (sample taken on 23 July). After home isolation and treatment, he was retested on 12 August, and the report came today (13 August). The interpretation says 2019 nCoV negative, but I am confused about the MS2 gene detected part. Is he still contagious? Does he need to continue home isolation for a few more days?

MS2 gene detected refers to internal control, not COVID positivity. It is done to ensure accuracy by detecting any technical failures. Since COVID gene is negative, he is not contagious and no further isolation is needed if symptoms have resolved.

I took the first dose of Covishield on 30th April. Since then, I have been suffering from fever around 102 degrees F and a dry cough. I have not received my COVID test report yet. I have a history of fever from a urinary infection. Can you please provide advice?

My RTPCR test was negative, but my husband test was positive. Since yesterday, I have been experiencing mild cough and body aches, but no fever. What should be my next steps?

Hi, I want to know. I got a COVID rapid antigen test after my blood report showed CRP at 52.4. My result was negative. Is this not the final result of my COVID test and do I have to wait for another report? If so, what is the other report if this is negative?
