Question about my first trimester screening results

Hi, I just had my 12 week scan for the nucheal fold translucency measurement & received my blood test results at the same time from the specialist.

He advised me the tests were very worrying and handed me a document outling my risk factor. He advised me my blood tests were the most concerning.

The entire risk factor ratio for Down's Syndrome is showing 1:2. Am I understanding this correctly in that I have a 1 in 2 chance of my baby having downs syndrome?

My MoM shows 3.496 - Free B-hCG & PAPP-A is 0./380 Mom.

The NT measurement was 2.5mm.

The Trisomy 21 showed background risk: 1:121, adjusted risk from US 1:77, adjusted risk from BC 1:3 showing adjusted risk 1:2

The specialist was very glum and apologised to give me bad news but said there have been false blood tests although to see adjusted risk1:2 is making me really concerned and wondering if it's almost diagnosed that my baby has Downs Syndrome.

He told me I need CVS or Amnio, I'm 13 weeks, 1 day.

Please help.

Big hugs to you

Unfortunately Yes 1 in 2 means there is a one in two chance your baby has downs. I had the results of 1 in 6 and had an amnio that showed our baby had downs syndrome. I found it to be the most difficult time of my life.

The best advice I can give is talk to a genetic counsellor - my ob organised mine - this was after we had our results but I found talking to someone about it very helpful. Not too sure what state you are in but mine was through King Edward Memorial Hospital in Perth.

You might need to think about whether or not you would continue with the pregnancy - DH and I had differing opinions on this and almost split us up.

We decided to say goodbye and it was not a nice experience. We got pregnant again 2 cycles later and have a healthy baby boy.

Sorry to hear you have to think about all this but 1:2 does mean what you think it does.

Speak to a genetic counsellor (OB should arrange this if not you can contact a major hopsital who will offer them)

Have a think about whether you would want to continue the pregnnacy or terminate and rememeber there are lots of people at BB who you can speak to for support and information.

So sorry for you to have to go throught this, but hopefully you feel that it is better to know before hand and have chance to come to terms with what ever happens, which remmeber there is also a chance that baby will be normal with no abnormallity.

HUGE HUGS
thinking of you
