NT results are confusing..can anyone help?

[adgal]

Hi all.  I am new here but a regular on the pregnancy 35+ forum.  I am currently 12.4 weeks pregnant and today had my nucheal translucency test.  I find the results confusing...

The nasal bone was visible and normal in appearance.  The nucheal fold was 2.1 (they told me anything under 3 is good).  In other words there were absolutely no physical markers of downs syndrome.  Based on my age (I am 40) and the blood results, they gave me a 1:13 chance of downs.  I am wondering how they can come up with a number like this given that physical appearance was normal. Everything was normal...it was measuring right where it should be, heartbeat was a strong 168bpm.  I have decided to have amnio as I prefer to know whether then wonder.  I will love my baby and know that he or she has something special to offer the world regardless of the turn out, but I feel the need to know.  I am wondering what your thoughts are based on these results?  Thanks so much for any input, I really appreciate it.

Like you said before this is only a screening.  Everything is going to be fine.  I pray for you all the time and I just know the Lord is going to make things perfect for you and Warren.  Keep going strong girl!

I did get 2 sets.  The first said risk was 1:73.  The adjusted risk is 1:13.  There were no soft physical markers, the adjustment was based on the results of the blood tests.  There was a high ratio between the free beta and the papp a (I think that's what it was called).  The nasal bone was present and nucheal fold was only 2.1.  My adjusted risk for trisonomy 13 and 18 were around 1:4000.

I believe she is correct about that.  I had a set of numbers based on my age and then with the test combined.  My numbers went up once the blood test and NT was done (combined).  Do you remember getting 2 sets of numbers.  The Trisomy 13/18 was the same way and those numbers really really went up.  But either way, everything is going to be just fine.

You should have received two sets of numbers. The first being based purely on your age and then the second being based with your age & the measurement of the nuchal fold combined. The 2nd set of numbers is the one you should take most notice of. With a measurement of 2.1 I'd have thought it would be a lot higher than 1:13. Well that is how things are done in the uk, things coud differ elsewhere. Good Luck with the amnio!
