20 week scan - short nasal bone - worried

We had our 20 week scan yesterday and baby's short nose bone was flagged (it was 4.1mm and hospital's threshold is 5mm) for referral to a consultant.

Consultant has advised that its likely baby is fine (rest of scan was normal) but there is a risk that it signifies a chromosomal abnormality such as Down's or something else.

The NHS's combined test at 12 weeks gave me a Down's risk of 1 in 148 but we had the private Harmony test which gave me a risk of 1 in 10,000.

We've turned down an amnio because of the miscarriage risk.

Can anyone offer any reassuring similar experiences??

I would be reassured by the Harmony test. That's pretty tiny odds. X

You've had the harmony test, those are great odds! my DD HAS downs and a perfectly normal nasal bone! Yours just has a small nose! :-) Smile

I would be very reassured by the Harmony results. From talking to a private Dr in this field it seems that the odds are actually even better than 1 in 10,000, in fact I was told they are as accurate as an amnio in practise.

If you are near London you might want to consider a private anomaly scan at:

They really are amazing and I had extremely reassuring scans and tests here when NHS ones were inconclusive.

Thanks all - yes, we'll focus on the Harmony test result
