Lyn, I had my 80th infusion yesterday and my titer was 2.49 the last time I was tested which was a month ago. 3 months prior it was 2.48. I will checking it every months.

I asked my MS neurologist your question yesterday and she said it's too complicated to give an opinion to someone she hasn't seen because they factor in a lot of information in making that decision here in America.

I hope you don't have to give Tysabri up. Best wishes.
