First trimester combined screening result

12 replies

Hi, I am 14 weeks pregnant and just got my first trimester combined screening result and was shocked to see it was 1 in 155. So although I am deemed low risk, and within the NHS will not be offered any further diagnostic tests, I am beside myself with worry, as I am so near the cut off of 1 in 150. I am 38 years old, this is my third pregnancy (I have 2 healthy little girls). My NT measurement was 1.9. Does anyone else have experience of this?

Where are you based? If its possible (with travel and finances) I'd be inclined to have a second set of tests privately. The results are often different and much clearer.. (and very quick)

Based in Bristol. The trouble is, now I am over 14 weeks, it is too late to have the tests repeated. I am seeing the midwife next week and going to ask her what she suggests. I was wondering if they would do the quadruple blood test or whether it is worth paying for a private ultrasound, so they can look for markers.

I've had very similar results. I'm 38 and it's my first baby. I'm officially low risk at 1 in 170 but doesn't feel low risk. I'm nearly 15 weeks so am going for a private scan. They can't do NF but maybe will be able to see other markers. My DH thinks I'm mad as we'll love the baby whatever. I'm on my way to the scan now so will let you know if they can test different things

Oh yes, let me know what they say at the scan. Good luck, thanks.

I had the test done privately as under the nhs test everything is combined, so your age really swings the result. I was 39 so my age alone put me at 1 in 130 before anything else. The private obstetrician I saw is very anti merging all the results as it treats older mums as a statistic rather than as individuals. Your actual Nuchal measurement is well within safe limits so looking at you as an individual that seems good. My private scan had my revised risk at 1 in 1800 as it looked at measurements and soft markers, and DD is a healthy normal baby and is thriving.

I went to one if the Spire hospitals and had a scan carried out by an obstetrician with 20 years experience working in this field. It cost £130.

Scan was lovely. Much longer than my 12 week scan. They couldn't redo the NF measurement but did check the heart and blood flow. Apparently my bloods pushed my risk so high. I've opted for the harmony test for peace of mind. I know that risk is relatively low just want to be able to relax and enjoy my pregnancy. I need to wait 2 weeks for the results.

I luckily had low risk results but I really don't understand why they mix in the age related stats with your individual blood profile and the baby's nt or nuchal fold. Surely the whole point of the info that is individual to you and your baby is that you don't have to rely on generic averages?

I had a low risk nhs combined test at 1 in 309 but wasn't comfortable with the numbers (my bloods were the main reason and age - 36) so I went for a private scan which put me into the high risk group at 1 in 87 as they use more markers. The Nf measurement was 2. I didn't want invasive tests so ended up going to holland for a DNA blood test called maternit 21 (same as harmony) at 15 weeks. You can now get the DNA test in uk - I know the fetal medicine centre in Harley street does it.
It measures the fetal DNA in the mothers blood and can detect if there is another chromosome.
I would advise going for this test as will give you peace of mind. It gives the same accuracy as the invasive testing.

Thanks for your responses everyone! I had never heard of the harmony test, until I started this thread! I have read up on it and going to have it in Cardiff on the 29th (I couldn't get in any earlier). I feel a sense of relief, that one way or the other, it will put my mind at rest. It is expensive though (£750). x

Betty - I've just had my harmony results from the clinic. Came back as 1 in 10000 for all 3 trisomies. I know it was a bit expensive but I just feel so much more comfortable knowing this and can now enjoy my pregnancy without worrying. I hope you hat the same great results

LostMySocks - that's great news! I get my results in a weeks time. Was lovely to see the baby on the scan again. All looked normal, so fingers crossed.
