offinthedistance, when you are in the strata trial for the jcv test they take your blood approx every 12 months and my Dr ordered one test outside of the trial.

Natalie, first let me say I am very happy for you that you have a plan of action and that you are healing well What a miserable ordeal When I have had pedicures I ask about their procedures - now I will be even more vigilante

Dr Vollmer and Dr Corboy of the RMmsC have told me there is a 1-3%margin of error in the jcv test. So, when I had one positive and one negative Dr Corboy considered me positive, when it became 1 to 2 he was more into considering me negative-now ...
