Screening with twins

[emma911030]

I'm after a little advice/ stories from people who have experienced.
I found out yesterday I'm expecting twins 🤯.
I spoke to one of the screening doctors after my scan about screening and what it means with twins. They say I have MCDA twins but I wasn't quite As ahead as originally thought so can't 100% confirm, so I am back next week for another scan. They have told me that I don't have to have it and they can just see what the scan comes up with (with regards to fluid on neck etc) and if it's increased they may suggest screening but that if they are identical it's likely to give a more accurate result as if one twin has high risk of downs then so will the other but if they are non identical if one is showing increased fluid then to have the screening might not actually give an accurate risk number because one the blood test might be scewed by one twin giving more of an influence if that make sense!
Who here with twice (either sort) had the screening and did you find it helpful/worth it? Or did you have it and it make you feel more confused?

Congratulations on your twins! I'm 14 weeks with DCDA twins and had the screening at 12 weeks and got the results a few days later. They told me the accuracy is slightly less accurate with 2 babies but I felt it was important for us to be prepared either way and I'm glad I had it. As mine as non-identical the results weren't exactly the same but were quite similar and the chances are very low for both babies. I'm quite satisfied.

I thought MCDA twins are always identical? Mine were and are!

I had MCDA twins (always identical) and had the normal NHS screening where they check the nuchal fold at the scan and then do a blood test. I was told i would get one result as they are identical so if one has a genetic abnormality then so would the other.

My results came back low so i didnt go on to have any other testing (NIPT or amniocentesis).

Congratulations on having twins by the way! My MCDA girls are 4months old and its very special xx

@Alwaysfrank @Wishing56 sorry yes I only said IF they are identical as they couldn't be 100% sure due to only dating 10+6 rather than the 12+3 my midwife had dated me as so they didn't talk to me in specifics towards identical that's all :) I'm back on Thursday (18th) and hoping the fluid on the one baby has reduced and it was just as the doctor suggested only there because the baby wasn't the size/development stage needed to be accurate.
