RW-- thanks for given Biogen hell!!! Maybe if we stay on them we will get info but it is shameless they blew off your doctor. I have an appointment with my neuro next week so I will ask her what she has heard, if anything. How much Vitamin D are you taking? Just curious. I am taking 4,000 a day (for about 5 months now) and plan to ask for a Vitamin D test when I go in just to see where I am at now.

Does anyone know anything about this CD4 T cell testing? Someone on another forum recently was talking about neuros doing this test now to watch for PML, and if the numbers got too low they were yanking the people off of Tysabri. I had never heard of this.
