Hi, I understand your plight. Ratio of less than 1:250 is suggestive of high risk of downs syndrome.
However, your wife's reports are much above the cut off levels. The nasal bone can be unossified in quite a few patients. In case of doubt do am integrated screening with a quadruple test & SOS genetic sonogram at 16 weeks.
Rest assured, her reports prima facie look normal.
