i am a bit concerned but even more confused about some test results that i have received related to risk for down syndrome. i am currently 33 years old and will be 34 when the baby is born. i had the sequential screening test done and my 1st trimester results came back fine (completed at 13 weeks, 2 days: 1.88mm nuchal translucency measurment with a 1 in 1,800 chance for down syndrome) but then after my 2nd trimester blood work, my final results came back with an elevated risk for down syndrome - 1 in 230 chance. i then had two high resolution ultrasounds done, one at 18 weeks, 4 days, which showed completely normal measurments as well as an echogenic focus in the right ventricle. the doctor did not seem worried about it. b/c of this finding in the hear, i had a second high resolution ultrasound, which was completed at 19 weeks 6 days and again, all measurments were completely normal and that doctor did not mention the echogenic focus and said the heart looked perfect. should i be worried about having a baby with down syndrome? should i get an amniocentesis??
