Your negative test results are conclusive. The particular kind of test (ELISA versus CMIA) make no difference. You do not have HIV. No more testing of any kind is necessary.

You do not need more HIV tests, however, HIV is only one of the STDs. A condom may not protect against HPV, Herpes, LGV, syphilis, pubic lice etc. It would be prudent to see your doctor for an evaluation. Visit this site for information: https://www.cdc.gov/std/default.htm Wish you good health!
