If you've recently acquired HIV, AIDS, syphilis or hepatitis A,B, or C, you may test negative initially.
STD Testing for HIV, AIDS, syphilis and hepatitis A, B and C detect antibodies that your body produces in response to one of these infections. It may take days or several weeks, depending on your immune system, to identify these infections.
If you believe you've been exposed and test negative, it is recommended that you are re-tested after your body has had more time to react.
Gonorrhea and Chlamydia have similar symptoms, but unfortunately often have no symptoms at all.
Each of these infections is caused by different bacteria and must be treated separately.
Hepatitis A, B, and C affect liver function and can lead to severe liver damage and liver cancer. While some cases of hepatitis A can be transmitted through water or food that is contaminated with fecal matter, often, all forms of hepatitis are transmitted through sexual contact or needle sharing.
Vaccinations are available to help prevent Hepatitis A, B, and C.
