There are established and strict criteria for the accurate measurement of the nuchal translucency.It is important for the measurement to be done properly to ensure an accurate result.
If your baby is not co-operating and the NT cannot be measured accurately, we may ask you to return for more images later in the day.
Occasionally, patients need to return on another day if the baby remains in an unhelpful position.
This means that combined first trimester screening will not give us a definitive answer.
For example, this test will not tell us "no, the baby definitely does not have trisomy 13, 18 or 21" and, this test will not tell us “yes, your baby definitely has trisomy 13, 18 or 21”.
For example, it tells us whether your baby has a low risk of having trisomy 13, 18 or 21, or whether your baby has a high risk of having trisomy 13, 18 or 21.
This test gives us an indication of whether we should worry about your baby based on these results.Combined first trimester screening is a non-invasive way of assessing your risk, which means it does not involve putting needles into the placenta or amniotic sac, as happens with CVS and amniocentesis.This means that combined first trimester screening simply tells us if your risk is low or high.I've heard that 12 weeks is really when the parts start to become noticeably different (because they both form from the same beginnings). We found out were having a baby boy at 14 weeks 3 days.They were doubtful because it was "early" but baby cooperated and it was clear as day that it was a boy! I really dont have a preference either way, I would just like to know so I could do some shopping!
