Hi, Erin. I was so glad to hear how far you've come!

My understanding is that blood is made up of red blood cells floating in a liquid called plasma. The antibodies that cause MG are also floating in the plasma. There's nothing wrong with our red blood cells, so there's no need to replace them--we can just replace the plasma. That's exactly what plasmapheresis does.

I'm just deducing an answer from the things I know, but it makes sense, doesn't it?
