Well I have completed one plasmapheresis oil change, it took most of a week, many sessions, many glitches and little to do but interact with @Tsing Tao, he has been spoiled. I'll give it a while and get a new full blood work up. I need to be careful for a while as the process removes antibodies though T cell, long term immunity, will be OK. I don't feel eighteen again just yet, tired and sick of needles after it. However, time will tell.
