Prenatal testing

Your first visit

At your first prenatal visit, your health care provider will perform a pregnancy test, if one hasn't been done already. Urine tests are most commonly used, but your health care provider will most likely order a blood test, which is more accurate, and can detect an ectopic pregnancy.

In addition, the blood test will check your:

  • Blood type
  • Rh type
  • Antibody screen
  • Hemoglobin and hemotocrit
  • Rubella antibodies
  • Syphilis
  • Hepatitis B
  • Gonorrhea culture
  • Pap smear
  • Urinalysis

These tests provide information about your current health, including any signs of infection or anemia. They also alert your physician to any conditions that could require special attention later on in your pregnancy.
