My Viral Capsid IGM Was Negative, But My IGG Was

Posted on Fri, 24 May 2019

Question: My viral capsid IGM was negative, but my IGG was 403. The confusing part is that my EBNA was in the 300s. I had the test done after being sick and then having a lingering sore throat for 2 weeks. Strep test was negative. Sore throat and swollen gland(s) persisted up until a day or two ago which is a month from when I initially became sick with what I thought was a cold virus. I am tired.
