33 yo,3rd pregnancy no pbs, nucal fold 2.1 @ 12 weeks, hcg 2.64 @ 17 weeks, 1:304 risk of T21, normal pre-morpho echo @ 19 weeks, is it high risk?

- the threshold set for T21 is 1/250, so you are not in the high risk area, though i would recommend an amniocentesis, as your age risk for T21 is lower than your biochemical risk ..

I am 31 yo, pregnant and my triple test put me exactly at the limit for trisomy risk... the morpho ultrasound showed everything is normal, and dr advised against an amnio. Would like a 2nd opinion plz

Obstetrics & Gynecology
- you mean 1/250 ?
triple test will give you risk percentage, as for amniocentesis, you will get the fetal karyotype, so we can check for chrom. 13 , so in tri. 13 you will have 3 nb 13 chromosomes .
