PRENATAL SCREENING & DIAGNOSTIC TESTING: WHICH TESTS ARE MEDICALLY NECESSARY?
The number of prenatal screening test options has increased in recent years. Non-invasive tests, such as ultrasonongraphy and certain blood tests, are part of routine prenatal care and can help determine whether more invasive tests are needed. Many tests, however, are often offered to all pregnant women. It is important to weigh the benefits and risks associated with these tests, which are not always without risk, particularly for the fetus.
