False Negative after 3 years?

Jan 15, 2011

Hi, I had unprotected sex with my boyfriend 10 years ago. I had a HIV test done 7 years ago when I was pregnant that came back negative. I had another child and again was tested negative 4 years ago. These tests were done in Australia and I was wondering could pregnancy cause false negatives as my eldest has had recurrent oral candida in my otherwise healthy child and am really worried. My husband was tested for HIV in my first pregnancy with me and was negative. There has been no other possible risk.

Response from Dr. Frascino


Could pregnancy cause false-negative HIV-antibody test results? Nope.

It is possible that pregnancy or past pregnancy can cause false-positive HIV-antibody test results due to the production of nonspecific cross-reacting antibodies.
