On day 6 after infection, I did an RTPCR test. Today is day 10, and my report has come back with a Ct value of 22/25. I do not have any significant symptoms now, and my sense of smell and taste are normal. Should I be concerned about this Ct value?

CT value less than 25 suggests high viral load but absence of symptoms is reassuring. Isolate for 10 days total or as per local guidelines.

Is there a test for the SARS-COV-2 virus?

Answered by Apollo Doctors

I recently tested positive for COVID 19 three days ago, and my report shows a CT value of 19.2. I am almost asymptomatic, with only a slight dry cough and occasional mild headache, but no fever. What does this CT value mean, and when should I get tested again to check if I am negative?

I am traveling to Nagpur on 9th September, and my second vaccine dose is scheduled for 28th August. Since Maharashtra requires a negative RTPCR test for entry, I plan to take the RTPCR test on 7th September. Will my RTPCR report show positive because I took the vaccine dose on 28th August, or will it be negative?
