This last moth tested blood again...value went down again ...started at 1.0... First 4 mos on Tysabri ...went down to .70... Last test done number is now down to .60 ..... AND I finally feel better

yes they monitor my blood every 3 months im positive for the jc viris it was 39 when i started but its down to 31 now ....

Hi @A MyMSTeam Member
I have had 3 tysabari infusions so far...I had a low positive but my neuro still thought my ms was aggressive enough to take the chance..we will keep retesting my blood every six months and then reevaluate at 23 months which automatically increases the risk....hoping there will be something even better by then....also still praying for my own positives with tysabari ...I've heard such inspiring stories

I was told about a month ago that my JC virus was very mildly positive and my neuro did not mention taking me off Tysabri.

I get monitored too every 3 months
