How to donate platelets
How I did it: Donating platelets involves a lot more time than donating blood. First they take the blood from you (with a large needle) then the remove the platelets and put the blood back in you. It's a little different than just donating blood. It was worthwhile but took a lot of time.
And I didn't want all that icky yellows stuff put back in me. The nurse told me it was fat in my blood. Yuck!
Lessons & tips: Relax, listen to music or read and don't eat a high fat diet before donating.
