Time to read 2 min

A double marker test is an examination of the foetus to detect the presence of chromosomal abnormalities. By checking for free Beta hCG (human chorionic gonadotropin) and PAPP-A (pregnancy-associated plasma protein-A) it can check for the risk potential of developmental syndromes.

The first trimester screening test is important for all mothers, especially if they are at a higher risk of having a child with a developmental disorder. You can get checked for your risk factor with ease, during the first trimester itself. It is also a critical screening examination that all pregnant women should take.

What is a chromosomal abnormality?

Within each cell there are 46 chromosomes present, with 23 matching pairs. While half the chromosomes are passed down from the mother, and the other half from the father, there may be abnormalities present within them.

Genetic disorders can be passed down in the foetus, which can impact the mental and physical development of the child. There can also be abnormalities present for the first time, without either parent having the risk factor present.

It is important to get a test done to determine whether the risk factor is present in the case of your pregnancy. A double marker test can be beneficial in determining the risk factor.
