Brief Answer:
Some information:

Detailed Answer:
Hello and welcome,

Minocycline is an antibiotic that fights bacteria. It only affects bacteria, not other microorganisms like viruses or fungi. As it does not affect viruses, it would not alter the antigen part of the HIV test nor decrease the antibodies you would have to a virus (the antibody part of the test).

By 5 years, if you have HIV, you would have detectable levels of antibodies to HIV. The 4th generation test is 99.97% accurate at detecting these antibodies by 3 months from exposure and increases in accuracy even further after 6 months.

So:
No, the minocycline will not interfere with HIV testing.
Yes, you can trust these test results.

I hope this information helps.
