Hi All,

I’ve researched as much as I can for anything to do with an increase JCV. Before I started on Tysabri I was 0.98. After 5 infusions I am now 1.76. I’ve read it can differ and change as in go and down but I can’t seem find anything that tells me he w much, or how much is ok/bad etc.

Can you let me know your thoughts?



I doubt this will answer your question, but might be useful.
