Wouldn't a positive result indicate autoimmunity though? Even if it is a low positive? They set a negative range, at-risk range, and a positive range.
Could you tell me more about these patients? Did they have the JC Virus and develop PML? Did they get better once rituximab was stopped and out of their system?
May I ask how you managed to get approved for both? I have been fighting for almost a year, through three different doctors, and have been denied all the way to the top. My most recent rheumatologist was confident last week that she can get it approved and even scheduled my first infusions for yesterday and today, but at the very last minute, we got word from my insurance yesterday morning that the pre-auth was denied. A peer-to-peer review between my rheumatologist and my insurance was done yesterday and they want us to submit an EMG report... Ugh!
