Prenatal Testing

Columbia Shores offers the following lab testing during your pregnancy. At your first visit your nurse will draw the following labs. These tests are required.

Blood type: This test will reveal your blood type, Rh type, and antibody factor. If you happen to have Rh negative blood, special monitoring will be necessary to check for Rh incompatibility and you will need Rh immunoglobulin

Antibody screen: This test will detect unusual antibodies that may have arisen in a prior pregnancy or blood transfusion.

Complete blood count (CBC): This test will check to see if you are anemic, which means you do not have enough iron in your blood. Platelet levels are also assessed. Some women become slightly anemic as pregnancy progresses.

Rubella test (German Measles): This is an antibody test to determine if you are protected from Rubella.

Syphilis screen: This test checks for exposure to syphilis. If present, treatment may be initiated so your fetus is unharmed.

Hepatitis B: This test will check for infections from the Hepatitis B virus, which can be passed to your unborn child.

HIV test: This test will check for the AIDS virus. If you have an HIV infection, you can be treated during pregnancy which will reduce the chances of you passing the virus to your unborn child.

Additional testing throughout your pregnancy

Pap Smear: This will check for abnormal cervical cells. Usually done every 2 years if normal.

28 weeks: REQUIRED Glucose tolerance testing. You will have to ingest a sugary drink, your blood sugar is then measured to check for a condition called gestational diabetes during pregnancy. If gestational diabetes is present, it will be necessary to keep your blood sugar at a normal level. This is done through dietary restrictions, but there are cases where insulin may be required. In majority of cases, gestational diabetes ceases after delivery, however women who develop diabetes during pregnancy should be carefully monitored for development of diabetes later in life.

If you are Rh negative a follow up antibody screen will be performed. You will also be give an injection of Rh immunoglobulin to prevent antibody formation.
