testing for PML

Post by Arcee »

Hi -

I've been reading through all the newly shared data and opinions on Tysabri and I have a question that maybe someone can answer. Does anyone know how the testing for PML is done? One description I read said they are taking "serial measurements of JC viral load" and I'm wondering just how those measurements are obtained.

Thanks,
Arcee
