Gestational Diabetes Test
What it's for: Some women develop a type of diabetes, called gestational diabetes, while they are pregnant. You won't be able to tell you have diabetes on your own. Women at high risk for type 2 diabetes may be checked at their first doctor’s visit. Untreated gestational diabetes can cause health problems for you and your baby before and after delivery.
How often: Your doctor will take a blood sample to test you once between 24 to 28 weeks of pregnancy. If you are at high risk for gestational diabetes, your doctor may test you earlier and may retest you again later in your pregnancy and for persistent diabetes after you deliver.
Hepatitis B Test
What it's for: If you have hepatitis B, you can give it to your baby during childbirth. That's why your doctor will use a sample of your blood to check for it. If you have hepatitis B, your baby will get several shots after birth to protect against the virus.
Who needs it & how often: All pregnant women are checked for hepatitis B. You only need the test once, at your first prenatal visit.
HIV Testing and Counseling
What it's for: Your doctor checks a sample of your blood to see if you have HIV, an infection that can lead to AIDS. You could pass this infection to your baby.
Who needs it & how often: All pregnant women get checked for HIV. You can "opt out" of being tested. You only need the test once during your pregnancy.
Rh Incompatibility Testing
What it's for: Rh factor is a type of protein that some people have on their blood cells. A blood test can check to see whether you have this protein. You do not have to pay extra for this test.
If you are RH-negative and your baby is Rh-positive, you have RH incompatibility. This difference between your blood and your baby's Rh-positive blood can cause problems during your pregnancy.
Who needs it: All women and their baby's fathers should have a blood test to determine whether both are Rh compatible. You can do this at a preconception visit or at your first prenatal visit.
If you are at risk for Rh incompatibility, meaning you are Rh-negative and the baby may be Rh-positive like their father, your doctor will give you medicines to prevent certain problems for your unborn baby.
How often you need it: After your baby arrives they will check its blood type. If your baby is Rh-positive, your doctor will give you a dose of medicine after delivery. If your baby is Rh-negative like you, then you do not need another dose.
Who needs it & how often: All pregnant women are checked for syphilis. You only need the test once at your first prenatal exam. You do not have to pay extra for this screening test.
