According to the notes he gave me, the assay is pretty specific and can pick up as few as 25 copies? of the DNA of JCV in a sample. He wasn't clear on who would be tested but is going to find out more info, but he believed that it was mentioned that it would be trialed and that it had been used on the blood samples from people who were in one or another of the trials (STRATA or TYGRIS) who developed PML and that in every case, they had tested positive for JC (unfortunately, it was after PML). I told him if it did require a trial, I wanted in on it.
He was much more positive this time around. I think being able to talk to others with more people on long term therapy with Tysabri made him a little more comfortable in waiting for the assay.
Running on battery here, back later.
