Medical Conditions - Nuchal Translucency Scan

A nuchal translucency scan (NT scan) is a non-invasive prenatal test that uses ultrasound to measure the thickness of fluid at the back of a fetus's neck. This measurement can indicate an increased risk of chromosomal abnormalities such as Down syndrome, Edward syndrome, or Patau syndrome. The test is usually performed between 11 to 14 weeks of pregnancy and is often combined with a blood test to calculate the risk of fetal abnormalities. A high-risk result may prompt further testing, such as chorionic villus sampling (CVS) or amniocentesis, to confirm the diagnosis.
