High-risk NIPT for T21 that turned out to be completely negative ā sharing my experience
I wanted to share my experience because I know how terrifying it can be to receive a high-risk NIPT result, especially when youāre told there is a significant chance of trisomy 21.
I had my NIPT through Prenato at around 16 weeks. My fetal fraction was 5%, and the result came back high risk for trisomy 21.
Obviously, I was devastated and terrified. I was 33 at the time of conception, and I had never expected to receive a result like this.
What made things even more stressful was that my nuchal translucency measurement had also been concerning. At my first ultrasound, it was around 2.17 mm, but on a subsequent measurement it was reported around 4.9 mm.
After taking the NIPT result and the increased NT into consideration, I was told that my estimated risk was around 73%.
Hearing ā73%ā made it feel like my baby probably had Down syndrome. I spent weeks worrying and imagining the worst.
However, my anatomy ultrasound around 18 weeks was reassuring. There were no obvious abnormalities, and everything looked good.
I eventually had an amniocentesis around 22 weeks. The first results (FISH) came back showing 0% trisomy 21 cells.
I still had to wait for the final karyotype, which felt like forever.
Then the final results came back: no trisomy 21 was found in 200 cells analyzed.
My baby did NOT have Down syndrome.
Iām sharing this because I know people often see statistics like āhigh riskā or ā73%ā and immediately feel like the diagnosis is almost certain. In my case, it absolutely was not.
The NIPT was a screening test, not a diagnostic test. Even with the additional NT finding, the amniocentesis was ultimately what gave us the definitive answer.
I also had a more complicated pregnancy because I have JAK2-positive essential thrombocythemia and acquired von Willebrand disease, so I was already being followed closely throughout the pregnancy.
After everything I went through, Iām incredibly grateful that I chose to have the amniocentesis rather than spending the rest of my pregnancy wondering.
For anyone who has just received a high-risk NIPT result: I know the waiting is horrible, but a high-risk screening result is not the same thing as a diagnosis. There can absolutely be good outcomes on the other side of that result. ā¤ļø
I hope sharing my experience can give at least a little bit of hope to someone currently going through the same thing.
