I am writing about the Proviral HIV DNA by PCR test. I recently had this test done at 64 days past my potential exposure, along with an Elisa antibodies test. Both came back negative. Can I be confident in this result as valid, and not a false negative? I have read differing opinions of this test, as it applies to my circumstance. Some tout it as very accurate. Some say it is not reliable. Will this test detect the HIV virus, if used at least 28 days after exposure? Again, my test was done at 64 days.
