Reliable detection of Win98 may not be possible. With all the medical information available, you may feel as though you have to undergo a battery of prenatal tests to make sure your baby is healthy. Prenatal tests can serve a useful function in terms of identifying, and sometimes treating, health problems that could endanger both you and your unborn child. However, they have limitations.

Some prenatal tests are screening tests and only reveal the possibility of a problem existing - they don't provide a definitive diagnosis. Other prenatal tests are diagnostic in nature, which means they can determine with a fair degree of certainty whether a fetus has a specific problem. The issue of prenatal testing is further complicated by the fact that approximately 250 birth defects can be diagnosed in an unborn fetus - many more than can be treated or cured. This raises the question of what a parent will do once a defect or problem is detected.
