This test, known as the Double Marker Test, is used to screen the baby for any chromosomal abnormality during a pregnant woman's blood test. It detects some conditions such as Down syndrome, Edwards syndrome, and Patau syndrome. The test usually takes place within the first trimester of the pregnancy; it measures levels of free beta hCG and PAPP-A to calculate risk.
The examination is part of routine prenatal care, especially among high-risk pregnancies. It has essential information to provide the parents and doctors making decisions about what further evaluation is needed or under what kind of care plan should be applied.
The Double Marker Test is a necessary part of prenatal care. Here's why:
The Double Marker Test is a very simple and non-invasive procedure usually done during the first trimester. It begins with taking a blood sample from the mother. This can be taken from the arm through the veins. As no fasting is needed, it can be carried out at any time of the day that suits one.
Once the blood sample is drawn, it is sent to a laboratory for further analysis. In the laboratory, the concentration of certain hormones and proteins such as free beta hCG and PAPP-A, pregnancy-associated plasma protein A are measured. All these markers combined with the mother's age, gestational age, and other parameters help to choose a risk score for chromosomal conditions.
The results are often combined with other tests, like the NT scan, to evaluate genetic risks further.
Proper preparation can reduce anxiety and make the test go more smoothly. Here's how.
The test benefits the mother and baby's overall health and care. Here are some perks:
