My original doc didn't have me checked for the first 5 years that I can recall (although that's not saying too much
, but my new neuro started me on regular blood tests after she added CellCept because I was still have relapses and lesions. She also had me do the expensive NAB test ($995 - be sure to send in the 20% liability-limitation amount because the insurance wouldn't pay more than $256.66 and the testing company says you will be responsible for all the insurance does not pay otherwise). Glad to see that it came back negative.
After initially having my blood tested every 2 weeks, I'm down to once every 3 months while I'm still on the CellCept. Which is supposed to be stopped when the Tysabri starts - maybe this month???
