Test or not?

Why would you consider prenatal testing? The vast majority of babies born are healthy, and there is not often a need for concern. However, some parents -- and some caregivers -- want to eliminate the worry of, various possible birth defects, such as chromosomal defects, birth defects from infection (including HIV and rubella) as well as defects caused by conditions such as fetal alcohol syndrome (FAS).

Prenatal testing

Many defects can be discovered during pregnancy via one or more prenatal tests. But how much you want to know is up to you. Some women feel routine testing is unnecessary in their cases, since the risk of serious defects for the majority of healthy and conscientious women is extremely small. They may also believe that a serious defect is likely to be discovered even without the test and don't want to spend their pregnancy worrying too much about those that aren't serious.
