Fetal nuchal translucency: a prenatal screening tool
1Indianna University, Division of Nursing, USA.
During fetal nuchal translucency screening, ultrasonography is used to assess for a fluid collection at the nape of the fetal neck. An abnormal fluid collection may be related to genetic disorders and/or physical anomalies. This screening is most accurate when performed between 10 and 14 weeks gestation. Analyzing maternal serum beta-hCG and pregnancy-associated plasma protein A levels increases the accuracy of 1st trimester screening. Nurse practitioners, midwives, and physicians can be certified in performing fetal nuchal translucency screening.
