Every parent-to-be hopes for a healthy baby, but it can be hard not to worry: What if the baby has a serious or untreatable health problem? What would I do? Is there anything I can do to prevent problems?
Concerns like these are completely natural. Fortunately, a wide array of tests for pregnant women can help reassure them and keep them informed throughout their pregnancies.
Prenatal tests can help identify health problems that could endanger both a woman and her unborn child, some of which are treatable. However, these tests do have limitations. As an expectant parent, it's important to educate yourself about them and to think about what you would do if a health problem was detected in either you or your baby.
In a developing child, prenatal tests can identify:
The last two items on this list may seem the same, but there's a key difference. Some prenatal tests are screening tests and only reveal the possibility of a problem. Other prenatal tests are diagnostic, which means that they can determine — with a fair degree of certainty — whether a fetus has a specific problem. In the interest of making the more specific determination, the screening test may be followed by a diagnostic test.
Certain prenatal tests are considered routine — that is, almost all pregnant women receiving prenatal care get them. They include things like checking urine levels for protein, sugar, or signs of infection.
Although your health care provider (who may be your OB-GYN, family doctor, or a certified nurse-midwife) may recommend these tests, it's ultimately up to you to decide whether to have them.
Also, if you or your partner have a family history of genetic problems, you may want to consult with a genetic counselor to help you look at the history of problems in your family and to determine the risk to your children.
To decide which tests are right for you, it's important to carefully discuss with your health care provider:
Some prenatal tests can be stressful, and because many aren't definitive, even a negative result may not completely relieve any anxiety you might be experiencing. Because many women who have abnormal tests end up having healthy babies and because some of the problems that are detected can't be treated, some women decide not to have some of the tests.
One important thing to consider is what you'll do in the event that a birth defect or chromosomal abnormality is discovered. Your health care provider or a genetic counselor can help you establish priorities, give you the facts, and discuss your options.
It's also important to remember that tests are offered to women — they are not mandatory. You should feel free to ask your health care provider why he or she is ordering a certain test, what the risks and benefits are, and, most important, what the results will — and won't — tell you.
If you think that your health care provider isn't answering your questions adequately, you should say so. Things you might want to ask include:
You also can ask your health care provider for literature about each type of test.
