My doctor's office called yesterday and said my index for JC virus is .78. She said that was on the low end of the spectrum? Is this true? I'm nervous to start.

Yes, it is a low titer. Here are the June 2014 Biogen numbers for those not on prior immunosuppressants...
JCV index less than 0.9 = PML risk of 1 in 10,000 during months 1 to 24.
JCV index less than 0.9 = PML risk of 1 in 3,333 months 25 to 48.
JCV index less than 0.9 = PML risk of 1 in 2,500 months 49 to 72.
