Last Monday we went for the first trimester screening (Nuchal Translucency test) in which they do an ultrasound to measure the amount of fluid in the back of the baby’s neck and the flatness of the nose. They also do a blood test to check for chromosomal abnormalities. Prior to this test, they base your risk on your age. So our baby had a 1 in 700 chance of having Down Syndrome (trisomy 21) and a 1 in 1300 chance of having Trisomy 18 or 13 which are rarer and more serious. Yesterday, I got a call from the hospital telling me that since the ultrasound and blood test results came back, our chances are now 1 in > 10,000 for both Down Syndrome and trisomy 18 or 13. Great news! Now we just have to be patient until the beginning of June for the next ultrasound to see if we’re having a boy or a girl.
Oh, and the ultrasound pics from last week SHOULD be up soon (hint, hint….Darren).
