Strrange lab results - VCA IgG elevated, but undetectable VCA IgM and nuclear antigen IgG...
Has anyone come across this pattern before, and what did you find out was the cause? I had 15 days of a bad sore throat and fatigue, recovered for 10 days, then became extremely ill for the past 4 days with fever up to 104, sore throat, swollen lymph nodes, etc...
Doctor ran tests on the 4th day of this recent sickness including the EBV panel (they did NOT include the early antigen, which I'm reading is key):
EBV Ab VCA, IgM is less than 36 (below Ref),
EBV Ab VCA, IgG is 176 (elevated)
EBV Nuclear Antigen Ab, IgG is less than 18 (below ref).
So, I'm reading that I could be in some sort of transient post-acute window before the nuclear antigen has turned positive, or I have some sort of autoimmune disease that is stopping me from making these antibodies?
