Tests done later in pregnancy
Gestational diabetes
During pregnancy, women undergo a test that checks for gestational diabetes,
the form of diabetes that develops during pregnancy. You are asked to
drink a special sugary solution, then blood is drawn, and your blood glucose
level is checked. Women with high blood sugar levels will undergo additional
testing.
Many women can control their blood sugar levels during pregnancy by modifying their diets. Other women may require insulin injections, and may be at higher risk for diabetes later in life.
Rh factor
Rh disease can occur when a pregnant woman who has Rh-negative blood type
is carrying a baby who has Rh-positive blood. The woman's body senses
the difference and develops antibodies to "fight" the different type blood.
Since the antibodies are almost never formed until late in the pregnancy,
the pregnancy in which the antibodies are formed is usually not at risk,
but subsequent babies may be. In future pregnancies, an Rh-positive baby
could be at risk of severe anemia during pregnancy. The anti-Rh antibodies
will go from the mother through the placenta and into the baby's bloodstream,
where they can destroy the baby's red blood cells. However, a medication
called RhoGam is available. The RhoGam destroys the fetal cells that get
into the mother's bloodstream before they can "signal" the mother's body
to form antibodies to the Rh factor on the fetal cells.
Fetal echocardiography
The Yale Fetal Cardiovascular Center is the most experienced and busiest
diagnostic and treatment service in New England. Many conditions can be
diagnosed and treated before the baby is born.
