I donate platelets with the Red Cross every month and I've got an app where they give me the blood pressure and hemoglobin level, and which used to tell me if I had Covid-19 antibodies before everybody did via vaccine or infection.

Before I donate I have to sign something that says, among other things "We're going to test your blood for AIDS and tell you if you have it, so if you don't want to know don't donate". I hadn't thought about the other things they test for but of course they don't want blood with Leukemia in it either.

Why wouldn't someone not want to know they have AIDS? Given the disease is not a death sentence anymore and the earlier you know better your chances of survival. The warning probably deters a lot of people who could have otherwise been saved by timely treatment.

You still need to get consent for that. Like, you can’t just assume.

Maybe it's part of the whole bug chasing phenomenon
