Bad NT scan results? N e one else dealt with this.

[jenandjon]

My NT scan was yesterday and the results ranged from 2.74 to 2.83.  I'm 13w2d and 34.  

N e one else have NT results around 3 or more and have a positive story to share?

Thanks,

Jennifer

I forgot what the results are supposed to be.. I know it depends on how many w and d's you are.. so someone that went in at 12w would be a different scale... what did the nurse say?

I found this

At 12 weeks of gestational age, an "average" nuchal thickness of 2.18mm has been observed, however, up to 13% of chromosomally normal fetuses present with a nuchal luncency of greater than 2.5mm, and thus for even greater accuracy of predicting risks, the outcome of the nuchal scan may be combined with the results of simultaneous maternal blood tests. The blood test is used to measure the levels of hormones - primarily hCG and PAPP-A. In pregnancies affected by Down syndrome there is a tendency for the levels of human chorionic gonadotropin (hCG) to be increased and pregnancy-associated plasma protein A (PAPP-A) to be decreased.

So for 13w2d it would be more... You will have to ask what the norm is for 13w2d but yours doesn't seem that far off...

Image 2 shows a baby with an NT of 2.9mm, which is at the upper limit of the normal range. Though the risk will be higher than the baby's in the first image, nine out of 10 babies with a measurement between 2.5mm and 3.5mm will be completely normal.

Mine is next Tues and I am so glad that you shared this information.  I am also getting the blood work done as well.

I dont think those results are really a problem. Mine came back at 2.0 and when  I asked my OB what the cutoff was and what was considered low risk/high risk he said as long as its under 3.0 he is happy and wont request any further tests. Also, if you are worried about things like Downs there are other markers that they look for i.e: nasal bones present etc. Remember too that these tests are only scans and cannot tell you for sure - my OB didnt even want me doing them because he said these tests can be so inacurate with so many false positives that there was no point in doing them, but I still wanted to do it regardless.
