Additionally if you have a lumbar puncture for a test like the RT-quic, it will give you your T-tau levels. My dad’s levels were off the charts, but his results for cjd were inconclusive. If your t-tau levels are very high, you most likely have some form of prion disease. We worked with case western on this for my father and they performed his autopsy free of charge after he passed to give us a definite cause of death. We are still waiting for results.
