What is the double marker test in pregnancy?

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.

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.

A double marker test can be recommended by a doctor in the following cases.

The test is an early marker test to check for Down syndrome.

The results for the double marker test can showcase risk of the child developing physical ailments long-term.

The test can check for Trisomy 18, which can be related to several birth defects and mental developmental issues.

The test can detect Trisomy 21, which is related to organ health disorders in children.

You may also want to opt for a double marker test as a regular screening test for your first trimester even if you don't have an inherent risk factor present.

There are two other critical marker tests that need to be done for foetus health assessment.

The markers alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG), and unconjugated estriol (uE3) are checked during the second trimester in the triple marker test.

You can perform the quadruple marker test by checking for levels of alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG), unconjugated estriol (uE3), and inhibin A.
