Let’s take a look at the risks that make it necessary for a pregnant woman to undergo a double marker test.

  • If the age of the woman is above 35 years.

  • There is a particular genetic problem in the family.

  • Women suffer from type-1 diabetes and depend on insulin.

 

 

How is double marker testing done?

double marker test is mainly based on the Nuclear Translucency Scan ie NT. The area under the neck behind the baby’s head contains a fluid, called a Nucleo translucency. Down syndrome is detected by checking the thickness of this fluid during a nuclear translucency scan. Doctors recommend this test if Down syndrome is suspected.

Simply put, this is a blood test done with ultrasound during pregnancy. With the help of this test, doctors check the blood of a pregnant woman and check the hormones and proteins present in it. Explain that the hormone that is tested in this test is called Free Beta HCG (Human Chronic Gonadotropin). At the same time, glycoprotein (a type of protein) and PAPP-A (pregnancy-associated placenta) are tested during this test when it comes to the proteins to be included in the test.

 

 

Double Marker Test Normal Values 

Test Talk about the normal value of double marker test, the average quantity of free beta HCG in the test results is 59,109 to 201,165 mIU / mL (milli-international units per milliliter) between the first quarter ie 9 to 12 weeks. Should be. At the same time, the amount of PAPP-A should be 1 MoM (Multiple of Median).

 

 

Double Marker Test Report Analysis

The results of this test indicate serious risks related to Down syndrome occurring in the future. These can be understood in some ways, for example, if the amount of free beta hCG found in the test exceeds the normal limit, it is considered a positive marker. This means that there are more chances of pregnancy with Down syndrome. While PAPP-A is measured less than normal in the second condition, this condition is also seen as a positive result for Down syndrome.

The results of these tests come in the ratio form. If the ratio is from 1:10 to 1: 250, it means screen positive. On the other hand, if the ratio is 1: 1000, then it means screen negative. Screen negatives are considered low threat targets. Now, let’s try to understand this ratio in easy language. A 1:10 ratio means that after 1 pregnancy, 1 baby may have this disorder. Similarly, a 1: 1000 ratio can be found in 1 infant after 1000 pregnancy disorder.

After getting positive results in both these situations, the doctor recommends further tests. These tests are necessary to confirm the risk of Down syndromes, such as amniocentesis and chorionic villus sampling (CVS) and testing of embryonic cells present in amniotic fluid.

 

Double Marker Test Advantages

There are several benefits of this test, which we are trying to explain here through some points.
