Just to share my Genetic Fetal Abnormality scan experience with Pro C. Anandakumar at Camden. He is a damn experienced gynae, practically knows everything under the sky!!!! We have a good chat. After the scan, he even walked out to chat with us.
I've asked about why did he only do it at 22weeks while others are doing at 19-20weeks. He has commented that all this while since 1970s is 22weeks, others have moved it forward because UK legistration has moved the legal termination term to 24weeks, more time given to couple to do other procedures/ investigations and thinking time. Scan done at 19-20weeks may not be able to detect all possible abnormalities as organs are not fully functioning as yet.
I've commented that I'm skeptical about this scan as I've done it at 32W and 36W, yet my girl has a hole in her upper left chamber and only "discovered" on day 2 of birth. 32W or 36W is too late for any detection because organs are kind of "cover" by the rib cage, back bones etc.
He has shared:
1) 1 in 350 people on the street has a hole in the heart and it's normal, no need to be alarmed.
2) It's normal for mother with diabetic tends to have a baby about 500gm above the bench mark while hypertension tends to have smaller birth weight.
3) Current bench mark is around 3.2kg.
4) Usually, 2nd baby will be about 200gm heavier than no.1.
Above is what we have chatted, please do not represent it to others. Thanks.
