    Default Downs Ratios at age 35+

    I am pregnant with my second child and my downs ratio's have just come back at 1:774.

    My obs has classified it as low risk, given my age is 36, but I just cant help feel nervous as its not in the 1000 like most people even some who are over 35. The neck fluid measured 1.3 which I thought was very low risk.

    Just wondering if any fellow bubhubbers around the same age could share what their ratio's were?

    I am only 22... however one of my babies nuchal fold was 5.5mm...... The Dr told me he only had a 25% chance of being OK.... Very scary odds. I had a CVS and my lil man is fine

    Your measurement is perfect..... the risk may be under the 1000 because of you age, may have bumped it up as they take alot into consideration. But I would not be worried if I were you. Remember it is not a diagnosis, it is only the risk.

    Anything over 1/300 risk is technically fine. A doctor would not suggest a CVS or an Amnio with such a low risk factor as you have.
    I am over 40 & mine came back as 1/304.
    Borderline. My Ob. left the decision up to me.
    I chose to have an Amnio & everything came back fine. My N/T Scan was fine it was the b/t b/c of my age that weighed against me.
    My DP felt I was worrying needlessly & he was probably right.

    Thanks Ladies, I guess its double what my 'age' ration should be so I'll try not to worry. This 2nd baby has just been so long awaited that I am just so scared at the same time

    I was 41 at the time I had my NT testing done (42 at EDD).

    My results came back:

    Trisomy 21
    1/37 (maternal age risk 1/45)
    My risk factor was higher because bub had a 4.1 NT measurement.

    Trisomy 18
    1/1620 (maternal age risk 1/115).

    Because of the high risk I opted for an amnio & all was well.

    I'm 33 and expecting my first baby in 5 weeks. My NT was 1.7. I did the Quad screen blood test and result came back at 1/760 chance for Down syndrome. I wanted an amnio anyway but I'm living overseas and they will only permit an amnio if the result is 1/300 or higher. I am STILL worried. After every scan (I get a monthly or fortnightly u/s here) I checked all the body part lengths and measurements online which is a dumb thing to do because babies grow at different rates and the ob said everything looks fine, but I won't be able to relax until after the birth and I know he's OK. Most people would be very happy with a 1/760 result but I am a worrywart.

    My result was 1 in 1100. Like you, I have friends who had results in the multi-thousands! So I thought mine was a bit tight, but apparently it is a good result. I'm 29 yrs old.

    I was 23, third baby - 1:85

    At 24, fourth baby - 1:5

    Very high odds, had amnio's both times and I have two very healthy happy boys.

    Bub #1 Age 28 - 1:16,000
    Bub #2 Age 30 - 1:164

    1:774 is still an excellent result for your age.

    Never ever did I think I would be in a high risk at my age, my ob even questioned why I wanted the NT scan.

    I sure all is fine however the only way to find out for sure is an amnio or CVS and both carry miscarrige risks much, much higher than your results.

    Goodluck

    There are other subtle signs - for example babies with down's syndrome don't usually have a nose bone. When I saw a nose bone at 12 weeks I was a happy mummy. You can see it really clearly here as the white streak on her nose: Nose bone
    So if you have a DVD of your scan go and have a look. I think my risk was about the same as yours at 34.
