Tysabri and JCV jump
Hi, I started Tysabri this year and had my JCV test done last month at my 6th infusion. My level has gone up from 0.98 to 1.76 since starting. Is it this normal? Thanks 😊

@sarah_brewitt This link might be useful. https://www.mstrust.org.uk/a-z/jc-virus-and-pml
Hi thanks for the link I’ve read that and how it affects the risk etc. The numbers/risk increase of pml doesn’t bother me. I’m more wondering about the jump over 6months - if that’s normal?
