No. Your HIV test result reveals only your HIV status. Your negative test result does not tell you whether your partner has HIV. Also, it is important that you make sure your test was done after the window period between possible exposure to HIV and the time it takes for the body to develop antibodies to HIV (which is what most tests look for). Most people will develop antibodies within three months, but it can take longer, including up to six months in some cases. HIV is not necessarily transmitted every time there is an exposure. Therefore, your taking an HIV test should not be seen as a method to find out if your partner is infected. Testing should never take the place of protecting yourself from HIV infection. If you are engaging in behavior that puts you at risk for exposure to HIV, it is important to reduce your risks.
