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?

A CT value of 19.2 indicates a high viral load. Despite being mostly asymptomatic, continue strict isolation and monitor symptoms. There is no need to retest immediately unless required for travel or discharge criteria.

I went to have a COVID test 5 days ago because I had certain symptoms. That day, I was put in a hospital ward with others who had similar symptoms and were admitted after the test. The next day, my test results came back negative. However, I did spend 1 day in that ward. On the discharge slip, doctors advised me to stay in isolation for 10 days, even though my test report was negative. I want to ask if there is a significant chance of getting COVID by staying in a COVID dedicated ward for one day? I wore a surgical mask the whole time. After coming back, I changed my clothes but did not bathe as I was having a fever. Today is the 5th day, and I am a little scared because I read that most patients develop COVID symptoms between days 5 and 10.

Does a normal Covid test identify which variant it is?

I recently had a bit of fever and a sore throat, so I tested myself for COVID 19 antibodies. Could you please help me understand my test report and advise on what it means? I have attached the report for your reference.
