possible false positive hiv test on fifth generation assay?

Hi I'm going through a really crazy situation right now I was hoping someone can help me here.

6 weeks ago I went for a normal check up and my doctor included all the tests including hiv. ironically I have been practicing abstinence for a year and a half since my last test so I didn't really have a risk but I didn't oppose the test.
Apparently my blood was sent to a lab that does fifth generation tests which I guess give you separate results hiv1/2 and Ag instead of just one result.

My test came back reactive for hiv-2 from this initial assay. The lab then sent my blood to a reference lab and they did a multispot and then my result came back negative for both hiv-1 and hiv-2. the final interpret was hiv indeterminate and they recommended a PCR for acute infection. mind you I actually live in the US were I guess HIV-2 is rare and I have been abstinent.

I was so shocked when I got the result (two weeks after my test) that I ran to AHF, they did two insti hiv1/2 tests for me and both were negative. I went again at 4 weeks after my initial test and it came back negative with the rapid test again. The primary referred me to a specialist but after seeing my rapid tests the specialist said he doesn't need to see me so I never got the PCR and I'm so confused and stressed right now.
I have never had any contact to acquire hiv-2 the only things I could dig in my mind as possible exposures would be I had a mole biopsy 3.5 month and one 5.5 month before my test and I had been on spironolactone 50 for four month and at the time of my test in case that makes any difference!

my last sexual exposure was unprotected oral sex (only oral sex no other sex) a year and a half ago and I had a fourth generation test after 5 weeks after that exposure which was negative.

What does this look like to you? Does this seem like a false positive?

The sensitivity of the tests mean that false positives are not uncommon.  False negatives are extremely rare.

If you had follow-up tests that had negative results, those are conclusive to rule out HIV, and you can be assured you got a false positive.

FYI, nothing you mentioned was a risk for HIV in the first place, so clearly you do not have HIV.

Thank you so much for your response, yes that's what I think as well unless my dermatologist reuses syringes which is highly unlikely in the US. Would you know if spironolactone causes any kind of late seroconversion? and are instituted hiv1/2 reliable?
Late seroconversion is an old myth. Move on because you are negative.
Your dermatologist is not drawing blood out of someone else then quickly injecting something into you so it doesn't matter if he uses the same syringe anyway. hiv is a fragile virus, instantly dead in air so the doc can't infect you.
Another thing you can do to make your life simpler in future is tell your doctor that you do not want to take hiv tests when you had no risk. That way you avoid the anxiety that a potential false positive brings.
