Do you still need a physical examination for donating blood many times? Will the blood center send you a text message every time to inform you of the blood test results?

Before and after each blood donation, it is necessary to strictly check whether the blood is qualified, no matter when it is qualified.

The nurse knew you before donating blood. After donating blood, all the blood is marked with symbols (the inspector doesn't know whose it is). Test twice with reagents from two or more different manufacturers or batches. If in doubt, confirm again.

Platelets were collected by machine once every 0/4 days in recent/kloc, and a text message was sent every time to confirm that the blood donation was qualified.
