Shift.ms is better if you're logged in

I'm a little worried & confused . I got diagnosed earlier this year. My neurologist did blood work on me and results came back good BUT on my jcv test it says it's abnormal high index and I was exposed but I'm negative?? I told him what's going on?? That sounds confusing! He said you're negative so it's ok. I'm just so not trusting with alot of people and worried. Anyone ever heard of this type of test result? I'm starting zeposia and they said it may cause brain infection because of jcv ? I'm just so confused!
