Week 12: The week with the 1st big testing decision!
This week we had our 1st trimester screen appointment. This involved another ultrasound (for a nuchal translucency screening) plus blood tests which combined, help to evaluate risk for abnormalities of chromosomes 13, 18, and 21.
The ultrasound was a lot fuzzier than the ones we had at our fertility clinic. It was fun watching it on a big screen in the room, though. The baby wasn’t particularly cooperative and was curled up in an awkward position that made the testing a little difficult. At one point they flipped around, and I also noticed that they were sticking one of their legs straight up/out at one point.
The ultrasound results were normal – the nuchal translucency, which is a collection of fluid at the back of the baby’s neck, measured 1.2mm. (Anything <3.5mm is considered normal.) That particular ultrasound test is generally only considered reliable when paired with one of a few different blood test options. The options we were presented with were the sequential screen (involves blood tests in both 1st and 2nd trimesters), the quad screen (would generally be done in the 2nd trimester), and the NIPT (non-invasive prenatal testing). There were also options to do more invasive testing at the appropriate point in our pregnancy like Chorionic Villus Sampling or an Amniocentesis.
After discussing the options with the doctor, we opted to do the NIPT, which tests fetal DNA that is found in the gestational parent’s blood (pretty cool!). Research suggests that the NIPT triggers fewer false alarms than some of the other screening options and is generally more accurate. I knew that I wasn’t interested in the more invasive tests unless they were necessary.
After this appointment I scheduled our 20-week anatomy scan ultrasound, which could be our last ultrasound!
