Friend had stem cell transplant and changed blood type. Not a zero sum phenomenon.
Painful and difficult.
With residual lung problems. Frankly I would have thought similar blood types would have been paramount in stem cell matching.
What happens if you’re in an accident and the ER quickly tests for blood type without knowing anything about the wacky stuff and gives you a transfusion for what it tests at? Does the test come back as both? Do you die from the wrong blood type or what?
There should be nothing painful about the actual stem cell transplant.. it’s basically a transfusion. There may be some bone pain as the cells rapidly grow in the marrow. (I Had one). But, I’ve never heard anyone call the process painful.
Most pain crime from gvhd or chemo related issues .
