             Nuchal Fold Measurement and
          Nuchal Translucency Measurement
▪ A measurement of 6 mm or larger is considered abnormal for a nuchal fold. – Nuchal fold measurements are performed later in gestation compared to nuchal
transluceny measurements.
▪ Nuchal folds are typically measured anywhere between 15 and 19 weeks, while the nuchal translucency measurement can be performed earlier and is most accurately measured between 11 and 14 weeks.
▪ Nuchal translucency is discussed further in Chapter 23.
