1 in 89 likelihood?: If a woman is told she has a 1 in 89 chance of have a Down syndrome baby, that means if she gives birth to 89 children, one will have Down syndrome. What nobody can tell is whether the Down syndrome baby will be the first baby, the 89th baby, or one in between. Here in the 21st century, there is new, very accurate, technology like Harmony which tests the mother's blood to look for the baby's DNA. ...Read more

28 years old, nuchal translucency with blood showed trisomy 18 risk 1:1300. Dr said it's fine, but i'm worried. Does this seem high?

28 years old, nuchal translucency with blood showed trisomy 18 risk 1:1300. Dr said it's fine, but i'm worried. Does this seem high?

Trisomy 18 risk: A result of 1:1300 indicates that in 1300 pregnancies with the exact same test results, only one of them will result in a child with trisomy 18. This is approximately a 0.08% chance of trisomy 18. This result gives a higher chance than the best risk group (less than 1:10, 000) but still reflects a low likelihood of trisomy 18. ...Read more

I'm 11w3d pregnant, I refused to have nuchal translucency test. If baby had down I would keep it anyway. My ob/gyn was so perplexed. Am I wrong?

No: Such testing is really about how much you want to know. Occasionally, the results of such testing can have management implications, usually not. As a rule, I avoid doing testing if I don't know what I'm going to do with the results. Sounds to me like you're one step ahead regarding the non-significance of the results. Good luck. ...Read more
