A member asked:
Can you pass out the day after donating plasma if you have a b12 deficiency? with a hematocrit of 42
A doctor has provided 1 answer
Yes: You can pass out from other causes such as a vagal-vaso response, but if you are not anemic, which a B12 deficiency can cause, it would be an unlikely cause for passing out.
