Yes. People are willing to lie for money, and a lot of those questions asked for transfusable blood products are asked to make sure donating is safe for both you and the recipient. Now some questions asked only impact certain blood products, aspirin only impacts the utility of your plasma platelets for example. Now those paid plasma centers ask a lot fewer questions as they only need to make sure you’d be okay parting with the plasma.

It’s regulated by the FDA and lying on those blood donation forms is a crime as its both a legal document and considered tampering with the blood supply. As with everything in the medical field there is a required paper trail.

EDIT: my blood product in my example was wrong. It has been updated. If you’re curious how I know so much about blood donation, my roommate works as a phlebotomist at a nearby blood bank.
