Several tests are commonly used to diagnose conditions prenatally. These include:
Ultrasound: A non-invasive imaging technique that uses sound waves to create images of the fetus, helping to detect structural abnormalities.
Amniocentesis: A procedure where a small amount of amniotic fluid is extracted from the amniotic sac to test for genetic disorders and chromosomal abnormalities.
Cell-free fetal DNA testing (cfDNA): A non-invasive blood test that analyzes fetal DNA circulating in the mother's blood for chromosomal abnormalities.
Quad Marker Screen: A blood test that measures four different substances in a pregnant woman's blood to assess the risk of certain birth defects.
