Hello,
How many weeks is your baby now? I was told by my c+ nurse that 高齡產婦 can do a blood test during around 11 weeks - named "1st stage intensive blood test" something like that (verbal translated from Cantonese name). Accuracy 99%. If you done this test, there is no need for you to do the 唐氏綜合症 test such as 抽羊水. Because 1). the recommended test (11 weeks) is to be done much earlier than 抽羊水(around 19 weeks) timing, risk to 產婦流產 is much more lesser, 2) accuracy is much more higher 99% vs 85%.
However, by my experience this test only provided by c+ doctors, not through civil hospitals. The civil hospital only provide tests of 度頸皮&2nd stage blood test&抽羊水, if your 2nd stage blood test tested by civil hospital resulted normal, they will not provide 抽羊水 service, however all tests accuracy only come up to 85%, you have to think about the rest of 15% risk of bb有沒有唐氏綜合症, plus they carry out these tests at quite later stage. I know this so well 'cos I experienced it, civil hospital will not tell you in advance the various ways of testing 唐氏綜合症, the test timing & the related advantage & disadvantage even if you asked them. All these info. I got from my c+doctor & nurse. I at lastly did the 抽羊水 at c+ after I found out such poor service level of civil hospital & because I don't want to bare the 15% inaccuracy risk of 唐氏綜合症 for my baby.
