My wife is currently 20 weeks pregnant. The NT scan conducted at 12 weeks showed a Nuchal Translucency of 2.4 mm (93rd centile, FMF) with visualized nasal bones. Subsequently, an NIPT test, as per the doctor's instructions, yielded a low-risk result. However, during the 20-week anomaly scan, the nuchal skin fold thickness was measured at 1 cm. The doctor indicated a potential chromosomal issue with the child. I'm uncertain whether to rely on the NIPT or the anomaly scan. What further test should we consider?
