pregnancy and HIV test
Jul 22, 2007
can pregnancy alter an HIV test result? like could it show up negative when its really positive because a woman is pregnant?
Response from Dr. Frascino
Rarely pregnancy or past pregnancies can alter an HIV-antibody-test result. However, it would not cause a false-negative test, i.e. a negative test result in someone who is really positive. Rather, it might cause a false-positive or indeterminate test result (positive or indeterminate result in someone who is HIV negative) due to cross-reacting nonspecific antibodies. These rare complications can be quickly sorted out by performing more specific tests.
If you tested negative beyond your window period, your result is definitive and conclusive, whether or not you're pregnant, OK?
