The fold is more focal and at the level of the posterior fossa. This measurement has a higher threshold of normal, although the implications of increased thickness are similar to those of translucency. The nuchal fold thickness is considered normal if under 5mm between 16 and 18 weeks gestation and under 6mm between 18 and 24 weeks gestation.
Perhaps the most common such test uses a measurement of the nuchal translucency thickness ("NT-test", or "Nuchal Scan"). Although 91% of fetuses affected by Down syndrome exhibit this defect, 5% of fetuses flagged by the test do not have Down syndrome. Ultrasound may also detect fetal organ anomaly.
The measurement is taken with the person standing upright, with arms hanging down loosely. The skin fold is pulled away from the muscle and measured with the calipers, taking a reading 4 seconds after the calipers have been released. [3] [4] The measuring point is halfway between the olecranon process of the ulna and the acromion process of the ...
A nuchal cord is when the umbilical cord becomes wrapped around the fetus's neck. [1] Symptoms present in the baby shortly after birth from a prior nuchal cord may include duskiness of face, facial petechia, and bleeding in the whites of the eye. [1] Complications can include meconium, respiratory distress, anemia, and stillbirth. [1]

This is untrue: At the end of the second trimester, the nuchal translucency can no longer be seen and instead the nuchal fold is measured. The fold is more focal and at the level of the posterior fossa. This measurement has a higher threshold of normal, although the implications of increased thickness are similar to those of translucency.
