Non-Stress Test in Pregnancy A non-stress test (NST) checks the health of your baby by looking at your babyâs heartbeat and movement during pregnancy. The test may be used when: â¢ Your baby is not moving as much as usual. â¢ You are near the end of pregnancy or past your due date. â¢ Your pregnancy is high risk. About the Test NST is often given after 28 weeks of pregnancy when your baby is able to respond to the test. â¢ For a high risk pregnancy, the test may be given before 28 weeks. â¢ If admitted to the hospital during your pregnancy, the test may be given 1 to 2 times a day to check the health of your baby.
Introduction. Nuchal translucency (NT) is the assessment of the amount of fluid behind the neck of the fetus, also known as the nuchal fold. An anechoic space is visible and measurable sonographically in all fetuses between the 11th and the 14th week of the pregnancy (Figure 1).he findings of numerous studies suggest that an effective first trimester screening for trisomy 21 can be obtained by the combination of maternal age and measurement of fetal NT [ 4 - 11 ]. At a risk cut-off of 1 in100, the detection rate of trisomy 21 is about 75%, at a false positive rate of about 2%.
