Early Anomaly Scan

If you're pregnant, you should get an early anomaly scan. It's a great way to check on your baby's health and make sure everything is developing as it should be. The doctor can check whether you have twins and any abnormality in the fetus can be diagnosed.

Overview of the Early Anomaly Scan

This anomaly scan is normally done at the gestation period of 20-24 weeks. During the scan, the pregnancy and the womb are examined thoroughly to check the parts of the fetus and the position of the placenta and assess the growth of the baby as per the gestation period and the amount of amniotic fluid present in the womb.

About the Early Anomaly Scan

The scan is done for the various parts of the body like the heart, brain, kidneys, stomach, face, limbs, bones, and spine to see that all is fine and there is no abnormality.

It is a medical examination carried out by a trained sonographer in the form of an ultrasound. Results are in a 2D black and white image as many countries do not use 3D or colour images.

This scan is good for women in the higher risk zone of having any kind of poor health condition of the baby. The first and early second trimesters are the perfect time for this scan to detect any fetal anomaly. However, the gestational age of 20-24 weeks should not be ignored for getting this scan.
