well we got the results back on the genetic testing and everything came back normal!! it has a 91% accuracy rate and there is more testing we could do that would put it at 95% but i think we are going to pass since everything was normal :)
below are is the testing we had done and what it all is
First Trimester Prenatal Screening Tests First trimester screening is a combination of fetal ultrasound and maternal blood testing performed during the first trimester of pregnancy. This screening process can help to determine the risk of the fetus having certain birth defects. Screening tests may be used alone or in combination with other tests. There are three parts of first trimester screening:
ultrasound test for fetal nuchal translucency (NT)Nuchal translucency screening uses an ultrasound test to examine the area at the back of the fetal neck for increased fluid.
two maternal serum (blood) tests The blood tests measure two substances found in the blood of all pregnant women:
pregnancy-associated plasma protein screening (PAPP-A) - a protein produced by the placenta in early pregnancy. Abnormal levels are associated with an increased risk for chromosome abnormality.
human chorionic gonadotropin (hCG) - a hormone produced by the placenta in early pregnancy. Abnormal levels are associated with an increased risk for chromosome abnormality.When used together as first trimester screening tests, nuchal translucency screening and maternal blood tests have a greater ability to determine if the fetus might have a birth defect, such as Down syndrome, trisomy 18, or trisomy 13.
