How does taking an HIV test help me? 1 If you test positive, you can take medicine to treat HIV. Taking HIV medicine as prescribed can make the amount of HIV in your blood (viral load) very low—so low that a test can’t detect it (called an undetectable viral load). Getting and keeping an undetectable viral load is the best thing you can do to stay healthy. If your viral load stays undetectable, you have effectively no risk of transmitting HIV to an HIV-negative partner through sex. 2 If you test negative, there are more HIV prevention tools available today than ever before. 3 If you are pregnant, you should be tested for HIV so that you can begin treatment if your test is positive.
