Lynn, wish it was better news for you. When I had been on Tysabri almost 4 years my jcv test came back positive. I stayed on Ty. Then when I had the test done at almost 5 years my test came back negative
. Doc said one of them was false but he still considered me positve. I had another test done a couple months ago at Quest labs-it came back negative-sooo, it appears the test done Nov 2010 which was positive was false. I am only telling you my story... You and your doc have to decide what is best for you!
Good luck and best wishes
