another one is, have you had allergies since you last donated?
i know some people just say to lie for every question. technically they screen every donation, but it’s not supposedly a reliable test for something like HIV.
i’m pretty sure i’m just allergic to reality. sometimes just constant sneezing, even when i’m on an antihistamine.
obviously best to just be aware of one’s behavior and risk factors. do they do this just avoid liability?
Are you sure that the question wasn’t asking if you have a condition which prevents scab formation? That might indicate a clotting disorder or some other problem that may make donating blood/plasma a bad idea for you.
