I got my 1st tri blood screening results back today. Everything at the NT Scan last week looked great. My risk of Trisomy 18 is 1 in 10,000.
My risk of downs syndrome before screnning just based on age (I'm 36) is 1 in 120 or a .8% chance.
Based upon my NT scan and the blood work my risk of downs syndrome is 1 in 145 or a .68% chance. This is considered positive. It's my blood work that threw the red flag. My HCG was high ( + marker) , but my PAPP-A was normal. In order to be considered negative I needed the risk to be 1 in 220 or a .45% chance. I know the chance of having a healthy baby is 99.32%, but I just wanted to hear "negative". I really just wanted something to come through easily with this pregnancy. I don't think that's too much to ask. Ugh.
So now we have to decide if we do further testing or just wait it out. CVS? Amnio? I'm sure we'll probably have to do one to find out for sure. This is such a ridiculious numbers game and I knew that going in to it since I've had friends with false positives AND false negatives and actually considered cancelling the tests. Ugh, again.
I wish DH was home.
