Diagnostic testing is different to screening and is used to determine whether an unborn baby has a congenital anomaly (such as a genetic condition) or gain more information after a structural anomaly was suspected through an ultrasound.

Diagnostic tests include genetic testing undertaken through chorionic villus sampling (CVS) or amniocentesis and may include ultrasound, fetal MRI and fetal echocardiography.

Like all diagnostic tests, there remain limitations to technology and knowledge. Diagnostic testing can provide answers, and will often also prompt more questions. It is important to discuss your concerns and questions with your antenatal care provider.
