1 in 138 for downs, 2nd time high risk

Hi there,

This is my 2nd pregnancy. I’ve been told I’m high risk with a 1 in 138 chance of Down syndrome. NT measurement was 1.8mm, Papp-a 0.4 & an HCG of 1.9.

I was also high risk with my first child, with a 1 in 33 chance. His NT was 3.2mm but the blood results were practically the same. I was 32 when my first child was born & I’m nearly 35 now. After later testing via NIPT we found he was fine & obviously he was born without downs.

I’m just wondering if anyone has been high risk twice? And has it just simply been the case that these abnormal or borderline bloods are just normal for you? After all we’re all different & they base these tests on the “average” person.

I guess just view it as a probability based on your circumstances and attributes.

1/138 suggests 99% probability everything is fine.
