If a gay man can't give blood in 2022, why can I?

Why were gay man banned from donating blood on March 24th, 1983?

Because of the AIDS epidemic of course. But a blanket ban for almost 40 years has a lot of people questioning whether or not this constitutes discrimination, or if it's a reasonable line of protection in the ongoing fight against the virus that causes AIDS. (Health Canada  has finally lifted the ban, instead basing ones ability to donate on sexual behaviours here)

But the blanket ban wasn't their first line of action, the CDC initially set-up blood tests at blood banks to screen potential donors for antibodies against the AIDS virus in their blood.

(From How To Survive A Plague by David France)
 

Since the tests proved to be highly unreliable, a blanket ban on blood donation from high risk groups was enacted, and remained in place until 2022. 

The unreliable tests they are referring to? The Elisa and the Western Blot.

Hold it right there. 
The Elisa and the Western Blot??
The current, similarly unreliable antibody test for Lyme Disease in Canada and the United States?
Same ones?

 For those that don't know, Lyme Disease is the single fastest growing vector-borne disease in the world. 

I took 4 Elisa tests in the last 2 years, and was negative for all of them so I never qualified for a Western  Blot. HOWEVER, because of symptoms that appeared right after a tick bite, I went on to get additional testing using ELISPOT (a superior testing method) in which I was positive for Rickettsia and Lyme Disease. 

So which is it?
Do I have it or don't I?
