I'm a 39 year old male.
Back in 2013 I had a no risk exposure (protected vaginal sex - unprotected oral sex with a csw).
Months outside the window period, I did an HIV Test just to ease my mind.
The doctor told me that my ELISA test was positive, so they sent my blood sample for an Antigen Western Blot test which came back negative.
They told me to repeat the above procedure after 15 days and I got the same results (ELISA positive and western blot negative).
9 years past and I found out that I may have gastric malt lymphoma.
This is caused by Helicobacter pylori, which I found out that I have, and from HIV or Hepatitis.
Yesterday I got tested for Hepatitis B (negative), Hepatitis C (negative) and HIV which came back positive again (it was an ELISA test like the previous time) and they sent it for a confirmatory test. I'm waiting for the results.
Is it possible that back in 2013 the 2 negative western blot tests, that I received after the 2 positive ELISA tests, were false negative tests?
If not, will I continue to get tested positive in ELISA tests even though I'm negative?
I had no other risk exposure since 2013 and only had sex with the same female partner which was tested negative at the begining of our relationship, and I'm her only partner since then as well.
Please let me know your thoughts.
