Many prenatal tests are performed routinely in all pregnant women. Blood tests, urine tests, and ultrasounds pose little or no risk to the mother or baby. These tests can provide valuable information to help your doctor care for you and your developing baby. Other tests come with significant risks. Therefore, these tests are only considered for women with high risk pregnancies.
Some maternal factors that can make a pregnancy high risk include:
Your doctor may recommend more invasive tests if your pregnancy is high risk, but the decision to have a test is yours. Understanding each test and what it measures, how reliable it is, and the risk associated with the test will help you make your decision. It is important to discuss your options with your doctor, especially if the test indicates there may be a problem.
Couples may choose to have certain prenatal tests for different reasons, including to:
- Allow for possible medical interventions that may be needed
- Begin planning for a child with special needs
- Identify support groups and resources
- Make a decision about whether to continue the pregnancy
