According to the Center for Disease Control and Prevention (CDC), 1 in 33 babies are born with a birth defect. Prenatal dna tests diagnose numerous genetic and neurological disorders during the first and second trimesters and allow soon-to-be parents to think about their options.

At the time of birth, you will be 35 years of age or older
There is a history of genetic disorders in your family
You have had a previous child with a birth defect
Other reasons that may be indicated by your physician
The results of a prenatal dna test can prove useful if your child will need immediate care. In which case, you can organize any needs in the hospital where the delivery will take place beforehand, …show more content…

Amniocentesis or Amniotic Fluid Test (AFT)
Gestation period: Between weeks 15 - 20
What it will detect: Down syndrome, edwards syndrome, patau syndrome, and neural tube defects that affect the spine or brain, such as spina bifida and anencephaly.
How it Works: A small amount of amniotic fluid (60 ml or about 2 Tablespoons) is removed from the uterus via the abdomen using a needle. Amniotic fluid contains cells that have been shed by the fetus, which physicians use in completing the analysis. The time it takes to actually retrieve the fluid will take about 1 minute, and your physician will receive the results in about 2 weeks.
Possible Risks:
Amniocentesis performed at or after the 15 week of gestation carry a 0.33% - 0.2% chance of a miscarriage. Other possible risks include Rh sensitization, infection and slight leaking of amniotic fluid - this normally stops within one week of the procedure.
Cordocentesis or Percutaneous Umbilical Cord Blood Sampling (PUBS)
