The distribution of the NT thickness for CRL has been reported in many studies. If both test comes back normal can we say for sure that baby will be ok.
My NT measurement was 29mm at high end of normal but combined with bloods we got back 1153 on the cusp of high high being up to 1153.

The median NT thickness for GA were 10 mm 12 mm and 14 mm for gestational age of 11 weeks 12 weeks and 13 weeks respectively and the 95th percentiles of NT thickness were 18 19 and 22 for gestational age of 11 weeks 12 weeks and 13 weeks respectively. The distribution of the NT thickness for CRL has been reported in many studies. Nuchal Translucency Normal Range Chart.
When the nuchal scan is done the doctor will share the results with you. At that time it is important to understand what a normal measurement is. For a baby that is between 45 mm and 84 mm in size a normal measurement is anything less than 35 mm.

The optimal gestational age for measurement of fetal NT is 11 weeks to 13 weeks and 6 days. The minimum fetal crownrump length should be 45 mm and the maximum 84 mm. I had a similar situation.
My NT scan measured 3738 mm and I was told by the high risk doctor that we would have only a 20 chance of having a healthy baby 50 chance of a chromosomal issue plus an additional 30 chance of a heart problem. I had a CVS done at 13 weeks and the FISH results and karotyping came back fine. During the routine first trimester screening at 13 weeks of gestation NT was measured at 3 mm.
The normal range of NT for this age is 16-24 mm. Nuchal skin fold NF measurements and prenatal follow-up ultrasound findings were normal. My NT measurement was 29mm at high end of normal but combined with bloods we got back 1153 on the cusp of high high being up to 1153.
NT Scan Measurement 19 mm at 13 weeksGuide me Please. Is it normal girls. When I went through the posts in this March Community I saw all of you are having bw 13 to 17mm.
I am bit worried. During the routine first trimester screening at 13 weeks of gestation NT was measured at 3 mm. The normal range of NT for this age is 16-24 mm.
Nuchal skin fold NF measurements and prenatal follow-up ultrasound findings were normal. Hi mum2be79 I had a 22mm measurement at 133 wks. Even though I am age 40 with a background risk of about 1100 the combined agescanblood results still came back with a much improved 1900 low risk.
So I think at 134 a measurement of 23mm is definitely normal. NT screening is usually done between weeks 11 12 and 13 12 but it must be performed between week 10 and week 13 of pregnancy. After that the tissue gets thicker and is no longer translucent so test results become inconclusive.
I am 30 years old and NT at 13 week pregnancy is 32mm. Double marker test showed low risk. Doctor opted TORCH infection screening now and aminocentesis at 16 th week.
If both test comes back normal can we say for sure that baby will be ok. Or should I think about abortion because NT is so high. During the routine first trimester screening at 13 weeks of gestation NT was measured at 3 mm.
The normal range of NT for this age is 16-24 mm. Nuchal skin fold NF measurements and prenatal follow-up ultrasound findings were normal.

The sonographers attempting to take NT measurements at the 1113 6 weeks scan should familiarize themselves with the above protocol. The scan can usually be done transabdominally and although a transvaginal approach is becoming increasingly popular to delineate fetal anatomy better at this gestation the measurement of NT remains easier.
The study results suggest a 25 increase in the detection rate of Downs syndrome using a combination of NT measurement at 120-140 weeks and MSM at 141-170 weeks for a 5 false-positive rate with modest increase in cost.
