Down syndrome screening

Down syndrome screening involves testing pregnant women to assess the chances that the baby may have Down syndrome, a genetic condition caused by an extra chromosome 21. The screening typically includes blood tests and ultrasound scans to measure certain markers and physical features. These results help healthcare providers estimate the likelihood of Down syndrome but do not provide a definitive diagnosis. If the screening indicates higher risk, more detailed diagnostic tests, like amniocentesis, may be offered. The goal is to provide expectant parents with information to make informed decisions about their pregnancy.
