During your pregnancy, you will experience a variety of exams, tests, and procedures. Some of the tests are routine for all pregnant women. Others are optional or may be recommended by your doctor in certain situations or if there are complications.
You should keep all appointments with your doctor so that problems can be detected as soon as possible. If any problems or
potential problems are identified, your doctor can plan for your
care as necessary. During each visit, your doctor will ask about
any symptoms or problems you may be having, particularly:
- Leakage of fluid
- Regular movement of your baby once you start feeling your baby moving
- Swelling of your hands or feet
Your doctor will look for and ask about signs and symptoms at the
various stages of pregnancy including:
- Symptoms of early pregnancy, such as morning sickness, breast
enlargement and tenderness, and frequent urination
- An embryo, viewed with ultrasound
- Enlarged uterus
- Enlarged abdomen
- Fetal heartbeat
- Movement of the baby
- Changes in your vagina, cervix, and skin
You will probably have the following routine tests and
- Pelvic exam, to determine the size of your pelvis and uterus
- Pap smear, very early in the pregnancy
- Weight measurement and blood pressure (at each visit)
- Determination of gestational age and due date
- Urine tests to check for protein, sugar, and bacteria
- Assessment of the size and position of the fetus
Blood tests to check for
diabetes, blood type, Rh factor, rubella antibodies, syphilis,
hepatitis, HIV, and other sexually transmitted diseases
- Exam of your lower legs and ankles for swelling
The Centers for Disease Control and Prevention recommends vaginal/rectal culture for
Group B streptococcus
(at 35-37 weeks of pregnancy) to prevent infection of the baby during labor and delivery.
Women with certain medical conditions have a higher risk of
having problems during pregnancy and, therefore, may need additional regular
prenatal testing like ultrasounds. Examples include women with
high blood pressure, diabetes, kidney disease, heart disease, multiple pregnancies (two or more fetuses), too much or too little amniotic fluid, or post-term pregnancy.
Additional tests may be done if
your doctor thinks
they are medically necessary. It may be done if your baby has a high risk of certain genetic issues or if you have had some complications in your pregnancy. Examples of additional tests include:
Triple/quadruple blood screen test—This test gives more information about risk of birth defects and includes tests for alpha-fetoprotein, conjugated estradiol, and human chorionic gonadotrophin, as well as Inhibin A in the quadruple screen. If the results are positive, this screening test may be supplemented by an
ultrasound or other tests to look for abnormalities.
- Nonstress tests—These tests check changes in the baby’s heart rate as it moves.
- Ultrasound—The ultrasound is used for dating of pregnancy or detecting abnormalities.
- Genetic testing—Preconceptional or prenatal gene carrier screening is recommended for genetic diseases in individuals are at higher risk of these conditions. Examples of people that may need this testing include persons of Eastern European Jewish descent.
—This test is used for detecting chromosomal abnormalities
and birth defects.
- Chorionic villus sampling (CVS)
—CVS is used for detecting chromosomal
abnormalities and birth defects.
If you have high risk factors for pregnancy complications, you may have additional tests and procedures. Examples include:
- Amniocentesis to determine fetal lung development
- Blood tests to assess clotting and liver function
- Biophysical profile—to check fetal health with
and a non-stress test
- Rh antibody screening—repeated at 28-30 weeks if you are Rh
- Stress tests to check your baby's health during uterine
- Vaginal "culture" for fetal fibrinectin—a screening test for likelihood of premature labor
