Ultrasound is one of the screening tests that may be done in the first trimester to look for birth defects, such as Down syndrome. The first-trimester screening test uses ultrasound to measure the thickness of the skin at the back of the baby's neck.
Some disorders can be detected before birth through prenatal diagnosis (screening). Birth defects may be the result of genetic or environmental factors. This includes errors of morphogenesis, infection, epigenetic modifications on a parental germline, or a chromosomal abnormality.
