They make me wait 56 days between whole blood donations. Exactly 56; I know because I tried to go on Day 55 once. How long do you have to wait after a double donation?
No clue, I only did a single of whole blood.
Weird... Instead of taking my whole blood, they only take my plasma, and instead of wanting you whole blood, they only want your red blood cells... Why don't they just take whole blood from both of us?
Well, I know that sometimes, only a unit of plasma is needed for some patients, but I guess you have a point. Why not just collect whole blood and separate the parts later? There must be some sort of problem with doing it that way...
And for the record, I'm not sure what blood type I have, (it's not even listed on my donor card ) but I think I was told it was some sort of B last time I donated.
