Give Blood!

[Ellisandra]

I guess RoChikita's worried about a tainted needle being stuck in her when she gives?
Because other tainted blood would have no bearing on her as a donor...unless a needle was reused on her from such a donor.

I'm 100% sure they don't reuse needles and the like at the bank I donate at, unless they go through the trouble of sending used needles back to be re-packaged, or they like, take them in the back of the office after hours and repackage them on site XD Which I highly HIGHLY doubt.

I don't know if every unit of blood gets tested or not, I know they take like two vials of blood on top of the unit and my guess is that that is tested, but on the back of the handout they give after donating it says to call them immediately if you feel sick or a fever in the next few days, just in case.
