Okay-first question. I gave blood like 2 weeks ago for the 2nd time, and it was whole blood. They said after giving whole blood you can come back and give after 56 days.

But they also said that they need my platelets, and with platelets you can give every week.

So if I gave whole blood, can I still give platelets before the 56 days are up?


2nd question-what's the most common type of blood?
