At least last time I donated blood in my country (Canada), you could discretely indicate “do not use” by applying a different sticker to the bag. This was done in case someone got peer pressured into donating but didn’t want to reveal something private that would have disqualified them otherwise.
We (India) don’t have that, mainly because blood bags don’t grow on trees, but there’s a question about sleeping eight hours the previous night that always seemed irrelevant. Now that I think about it, it might have been added for this purpose.

Yes but they also test the blood and will call you if they have reason to believe you are positive.
Roughly the same here in Germany
