Do you need to be tested for an STI during pregnancy?

An STI during pregnancy can pose serious health risks for you and your baby. As a result, screening for STIs, such as human immunodeficiency virus (HIV), hepatitis B, chlamydia and syphilis, generally takes place at the first prenatal visit for all pregnant women. Gonorrhea and hepatitis C screening tests are recommended at least once during pregnancy for women at high risk of these infections.

Even if you have been tested for an STI in the past, testing again during pregnancy is important. Be sure to tell your doctor if you have symptoms or have engaged in high-risk sexual activity. It's possible to have an STI without symptoms.
