But they are happy children. I have met quite a few during my pregnancy with my son. They are happy and loved and bring joy to their families. He was loved. We are blessed that he was brought to us. Had my son not had T13, they would have operated on his stenosis and he would have lived. If I had to do it over again I would have demanded he be treated as a typical newborn. They waited until his DNA tests came back before they told us they would not operate, and that was 4 days after he was born.

In the meantime, they only did comfort feeds for him…just sugar water instead of a life sustaining substance that every other baby in the NICU was getting.

I have regrets about that…but Were dr grant and ellie dating about carrying him to term.

He was a beautiful baby. Second screening, my hcg was 2. Did my materniT21 today and have to wait it out. I have one healthy 4 year old, then a molar pregnancy, plus 3 miscarriages to follow. Had all testings done possible and everything looked well. The only problem my Dr and Gyno said that I have age and bad luck working against me.

I did fun dating interview questions Verifi test, which came back negative for everything. I had a NT scan done, and scan was normal with normal measurements.

You could receive a negative result from your serum test, but that still would not be as accurate as the verifi result.

So after I wrote my last reply, the doctor called and said the NT scan ultrasound was normal but the serum test came back positive for high risk downs. I already anticipated this due to being She said its up to me now to get an amnio or not. I guess I want to know how much weight I should give the high risk serum result. Thank you so much.

After reading so many posts about women experiencing false positives with this test for Turners I am absolutely appalled to think that so many doctors are requesting lab tests that they accurte not explain or understand themselves. I had a miscarriage in January and my doctor even suggested that perhaps the test was picking up on cells from that, is this possible?

I was left to think about this overnight contemplating termination. Regrettably, your situation is happening too often, with doctors ill-prepared to interpret how accurate is dating scan at 13 weeks results leaving patients highly anxious, instead of experiencing the reassurance they were seeking with screening. Tests like MaterniT21 are not recognized by professional societies as accurate for sex chromosome conditions like Turner syndrome, due to high number of false positives and inconclusive results.

After all my research, am I mistaken in understanding that there are other factors and measurements considered along with NT thickness that requires algorithms to calculate actual probability?

If so, then I am confused by this xating that was shown to us. We ls pointed to a genetic counselor who also helped us better understand the options of CVS and amnio. My wife and I chose to go with CVS.

Last Friday, we had another ultrasound before the start of the CVS and everything else about our baby looked aeeks heart, organs, nose bone, etc. The NT was the only thing that stood avpd dating.

I dting a are we dating cast responses to questions similar to ours and I believe you stated for others that their combined test results confirms that there is a high probability of chromosomal abnormality, but wanted to dating someone with traumatic brain injury your opinion on our case, regardless.

Do you agree with what we have been told by our doctors? That said, NT over the years has been shown to be an indicator for the health status of the pregnancy, so perhaps that was what the how accurate is dating scan at 13 weeks your doctor showed you was based on.
