will antibiotics taken 1 week before the Elisa give false negative

Question

Iam a 30 yr old male , I had a exposure to a girlfriend of mine on the 14th of April 99, and I took the ELISA and the rapid test on the 14 of December 99, and I was negative, but I took again on the 14 January 2000 as I was not sure whether the test would have given me a false negative for a flu and cough I had.
