If partner tested negative stds can you still be positive?

It is still possible for you to be positive for a sexually transmitted disease (STD) even if your partner tested negative. This is because the test your partner took may not have been accurate, or they may have been tested too early after exposure to the STD. Additionally, some STDs, such as HIV, can take several weeks or even months to show up on a test. If you have any symptoms of an STD, it is important to get tested as soon as possible.
