When Down's Syndrome risk (NT measurement) is high in your 20s

[Acutesomething]

Hi everyone

I had a google but couldn't find the info.

If a woman at early twenties (22-23) is given a 1 in 20 chance that her baby has Down Syndrome from NT measurement (CVS later came back negative for Down's) does it mean she is likely to have a baby with Down Syndrome if she tries to conceive in her 30s?

Does anyone know why a young woman might have had such a high NT measurement? I know the risk goes up from 35+. She isn't aware of a genetic links in the family.

Thank you!💐

This article doesn’t’t really answer your question directly, but does explain that many people with high NT results don’t have Down’s syndrome babies, and the NT test is one of many screenings done.

Forgot to say, I had a high double test result in my first pregnancy but don’t recall my second pregnancy being at high risk (both pregnancies early thirty).

@Acutesomething every woman's chance of having a baby with Down syndrome goes up with age because age is a contributing factor.

If someone came out high risk in their 20's but this was a false positive (as in the baby didn't have Down syndrome), then I believe her chances would be the same as anyone for the age she'd be in her 30's if she got pregnant again (so no increased risk). If a woman in her 20's actually had a baby with Down syndrome (so high risk result was accurate), I believe the chances of having another baby with Down syndrome are (very) slightly increased (but still small) should she get pregnant again.

@Riverlee Thank you for the article and for sharing your experience.
@Aria2015 Thank you for explaining it in clear, plain language.
You've both been a great help, thanks.
