As @Hip mentioned, I've always read everywhere that 1:320 or greater is very likely an active infection. With that said, if you read the notes after the result, they consider a fourfold increase strong evidence of a current or recent infection, and I believe 1:160 would be a fourfold increase. The question then is did you recently acquire this infection, secondary to your ME, or has it been active since the ME started. Unfortunately it's not a question that's easy to answer at this point. One option would be to try treating the infection and seeing if it improved your symptoms at all. As you're on a different treatment path presently this probably isn't a good option right now. You may think about getting a consult with Dr. Chia though to see what his opinion would be.@halcyon @Hip and @jstefl
I am reviving this old thread to get some more info about these enterovirus tests.
I did these specific tests through ARUP labs and it took over a month to get the results back but I finally got them today. I was wondering if you guys could offer your interpretations (and I of course will be speaking with my doctor and am not taking anything here as medical advice.)
On Coxsackie B Virus, Type 4, my titer is 1:40 (and all other Coxsackies are negative at <1:10 per range)
On Echovirus 11, it was flagged as abnormal with titer at 1:160 (and it should be under 1:40 per range.) All other echoviruses are negative at <1:10 per range.
Thank you for any feedback.
