The published odds of having a child with Down's is 1 in 30 at 45
yrs of age. The odds of miscarraige are extremely high. Not just at 45
, but with every yr over 35, the odds increase. A Nuchal Translucency scan can be performed between 11-14wks. It is a non-invasive procedure which tests for Down's amongst a few other genetic defects. It is not 100% accurate. But, if an amnio is not desired, it is the best way to test. Amnio is far more accurate.
