If your blood is Rh negative and your partner's is Rh positive, you may develop antibodies that prove dangerous to your fetus. This can be prevented through an injection given around the 28th week of pregnancy.
Health care providers now routinely offer to screen for these disorders even when there's no family history. These can include: First trimester screening : This test includes a blood test and an ultrasound exam. It helps to determine whether the fetus is at risk for a chromosomal abnormality such as Down syndrome or birth defects such as heart problems.
Ultrasound : This safe and painless test uses sound waves to make images that show the baby's shape and position. It can be done early in the first trimester to date the pregnancy or during weeks 11—14 as part of the first trimester screening. Women with high-risk pregnancies might have multiple ultrasounds during their first trimester.
Chorionic villus sampling CVS : This test checks cells from the placenta to see if they have a chromosomal abnormality such as Down syndrome.
These usually involve blood tests and an ultrasound. They also check your baby for heart abnormalities, cystic fibrosis, and other developmental concerns. This is all pretty heavy. Second trimester screening tests may occur between 14 and 18 weeks. If any of these screening tests show abnormal results, you may have follow-up screens or diagnostic tests that give your doctor more detailed information about your baby.
A special ultrasound, called a nuchal translucency ultrasound, is performed between the 11th and 14th weeks of pregnancy. During the first trimester, your doctor can order two types of blood tests called a sequential integrated screening test and a serum integrated screening.
Your blood will also likely be checked for anemia. A blood test will also be used to check your blood type and Rh factor, which determines your Rh compatibility with your growing baby. You can be either Rh-positive or Rh-negative. Incompatibility occurs if a woman is Rh-negative and her baby is Rh-positive. Chorionic villus sampling CVS is an invasive screening test that involves taking a small piece of tissue from the placenta. Your doctor may suggest this test following abnormal results from an earlier noninvasive screen.
There are two types of CVS. One type tests through the belly, which is called a transabdominal test, and one type tests through the cervix, which is called a transcervical test. Testing has some side effects, like cramps or spotting. During the second trimester, a more detailed ultrasound, which is often called a fetal anatomy survey, is used to evaluate the baby carefully from head to toe for any developmental issues.
A quad marker screening test is a blood test conducted during the second trimester. A quad marker screening is typically offered if you start prenatal care too late to receive either the serum integrated screening or the sequential integrated screening.
It has a lower detection rate for Down syndrome and other issues than a sequential integrated screening test or serum integrated screening test. A glucose screening test checks for gestational diabetes , a condition that can develop during pregnancy. Gestational diabetes can increase your potential need for a caesarean delivery because babies of mothers with gestational diabetes are usually born larger.
Your baby may also have low blood sugar in the days following delivery. Some doctors prefer to solely perform the longer glucose tolerance test.
