Blood tests during pregnancy are very essential as they give a clear picture of the growth and development of the foetus and provide valuable information about the health of the foetus whether it is growing normally or if it has any health complications or associated anomalies.

The Quadruple Marker test also known as the Quad marker screening screens for various abnormalities in the foetus if present during pregnancy and is one of the most efficient tests that can detect anomalies at the very early phase of pregnancy that helps in further diagnosis.
