Birth Defects Testing - Deciding About Testing
The decision to have a test for birth defects
is personal. You have to think about your age, your chance of passing on a family disease, your need to know about any problems, and what you might do after you
have the test results. Your spiritual beliefs and other values also may play a
role in your decision.
Some birth defects—such as a
cleft lip or
cleft palate or certain heart problems—can be fixed
with surgery after birth and sometimes even with surgery during pregnancy. Some
other defects cannot be fixed.
