Last blood draw showed high RBC and Hematocrit. I am coming up on my window to donate blood and I am thinking about doing a double red cell donation instead of just whole blood. Can those that have done a double red chime in here and let me know if this is a better option then just donating whole blood? I am guessing yes but that will also double the amount of time I have to wait for the next donation from 8 weeks to 16 weeks. Worth it?
