By Mayo Clinic staffYour health care provider or a genetic counselor will help you understand your amniocentesis results.
For genetic amniocentesis, test results can reliably rule out or diagnose various genetic disorders — such as Down syndrome. Follow-up testing isn't usually necessary. Amniocentesis can't identify all birth defects, however, including heart defects, clubfoot, or cleft lip and palate.
If amniocentesis indicates that your baby has a chromosomal problem or a hereditary disorder that can't be treated, you may be faced with wrenching decisions — such as whether to continue the pregnancy. Seek support from your health care team, your loved ones and other close contacts during this difficult time.
For maturity amniocentesis, test results can reliably indicate a baby's lung maturity. If you need to deliver the baby early, this information offers reassurance that your baby is ready for birth.
