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.
