Should I trust the NHS combined tests?

Morning Everyone,

We received some sad news yesterday at our 12 week scan that one of our twins has an abnormality - Anencephaly to be precise.
Twins are DCDA so have separate sacs and placentas.

The midwife/sonographer was quite anti-testing the healthy looking twin because she said the results from the poorly twin may affect the outcome? I'm also led to believe that result accuracy for DCDA twins is less accurate anyway because it doesn't necessarily pick up for both? (Not sure about this)

I'm due to see a Consultant next week to discuss options of continuing with the pregnancy but I had a call from the midwife yesterday saying the lab had agreed to do my combined screening tests with the blood and 1.3 NT that had been taken, taking into account I'm 31 and have no health conditions.

Does anyone else find this strange? The midwife/sonographer (same person who called me) wasn't keen on me doing the test and I was okay either way with what their advice was. Then she calls me and tells me they are going to run them.

I'm just a bit concerned that the result accuracy is difficult anyway but adding in an already known abnormality, may affect potentially an otherwise healthy outcome of the other twin? I just have a horrible feeling I will be getting a call about high odds and go through that alongside discussing losing the twin too..
