First Trimester Combined Screening(also known as OSCAR)Nuchal Translucency (NT) Ultraosund scan together with serum biochemistry (PAPP-A and beta-hCG). This scan and blood test is performed between 11 weeks and 14 days of pregnancy. It can detect up to 90% of all pregnancies affected by Downs syndrome. As an alternative, Dr Chang also recommended the NT scan combined with the Panorama test (NIPT) at 11-14 weeks. This can screen for up to 99% of all pregnancies affected by Down’s syndrome.
Fetal Anomaly Ultrasound ScanThis scan screens for major fetal malformations, including abnormalities of the brain, face, heart, lungs, intestinal system, kidneys, spine and limbs. It is performed between 18 and 21 weeks of pregnancy.
Growth and Doppler Ultrasound Scan(Uterine, Umbilical, Middle Cerebral, Ductus Venosus) to help detect early signs of oxygen deprivation in the growth restricted fetus.
Invasive fetal medicine diagnostic procedures diagnose fetal chromosome abnormalities (Downs syndrome, Edwards syndrome, Pataus Syndrome).
