wen1982, everybody's risk is different. You have to look at the background risk (calculated based on your age, weight etc). If the calculated risk is lower than your background risk, then it means you have high risk. My DS ratio is 1: 10947 (background risk at 1: 547), thus the ratio was ok. But for ES, my ratio was 1:284 (background 1:1406) and PS was 1:1021 (background 1:4390), thus for ES and PS, my risk is high as my calculated ratio was much lower than my supposed background risk. So if your gynae says your result is ok, it means ok. Dun worry ya.
Hoping for hope, i did my oscar at NUH too. I like the nurses and sonogrpahers there. Very friendly. 1.4mm is good. Anything below 2.5mm is healthy. So dun worry. so far I did my oscar and amnio at the fetal care center. In fact, both sonographers are very good. They tell me what they are scanning, hands, head etc and what measurements they are taking. In fact for my oscar, i was given 3 very clear pics of my bb. I am only doing my oscar and detail scan at NUH. My gynae is from else where so I get to scan with every gynae visit. How much is the gynae package at NUH? Seems stingy that still have to pay to scan. Unless the package is very cheap. My package starts from week 16 and cost $550 (before gst). My assigned gynae at NUH for Oscar and detail scan is Prof Biswas. Heard that he is a very good and famous gynae there. Heard of him?
