Obstetrical Color Doppler
What is Obstetrical Color Doppler?
The obstetrical color doppler test is an imaging test performed as a part of biophysical profile (BPP) during the third trimester of pregnancy. This test uses ultrasound to create an image of the blood flow in the umbilical cord concerning both mother and fetus. It also helps to study blood circulation in the baby, uterus and placenta.
Obstetrical color doppler is recommended to identify cases of multiple fetuses, to diagnose conditions like high level and low level of amniotic fluid and to detect reduced movement of the fetus during the third trimester.
No injurious effects have been identified from ultrasound scanning of the fetus. Since ultrasound is so widely used in pregnancy, it is essential to ensure its use remains safe.
Why is Obstetrical Color Doppler done?
- To diagnose and assess fetal health conditions like intrauterine growth retardation or IUGR, reduced movements of fetus in the third trimester
- To identify cases of multiple fetus
- To diagnose conditions like high level of amniotic fluid (polyhydramnios) and low level of amniotic fluid (oligohydramnios)
