Know more about this test

The Double Marker Test- First Trimester also known as a dual marker test, assesses specific biomarkers in a pregnant woman’s blood. It is done during the first trimester of pregnancy, usually between 11-13 weeks. This test provides information about the risk of certain birth defects such as Down syndrome (Trisomy 21), Edward syndrome (Trisomy 18), and Patau syndrome (Trisomy 13) in the developing fetus. It is available at an affordable price in Kolkata with Tata 1mg labs.

This test measures the levels of two biomarkers in the mother’s blood: human chorionic gonadotropin (hCG) and pregnancy-associated plasma protein A (PAPP-A). The levels of these markers, along with maternal age, gestational age, and ultrasound findings help determine the likelihood of chromosomal abnormalities in the fetus. These abnormalities can lead to various genetic conditions that can affect the baby’s growth and development. Therefore, their early detection is vital for ensuring comprehensive prenatal care and addressing potential health challenges effectively. No special preparation is required for this test.

What does Double Marker Test- First Trimester measure?

The Double Marker Test- First Trimester measures two biomarkers in maternal blood associated with chromosomal abnormalities.

a) Free beta-hCG (human chorionic gonadotropin): a hormone made by the placenta shortly after a woman becomes pregnant.

b) PAPP-A (pregnancy-associated plasma protein-A): a protein made by the placenta during early pregnancy. It helps the placenta grow and function properly.

These, along with the USG marker and nuchal translucency (NT) measurement, are effective in Combined screening for Down syndrome and trisomy 13/18 in the fetus. This test only gives the risk for the presence of these chromosomal abnormalities in the developing fetus. A positive screen is not diagnostic but indicates that further evaluation should be considered.

hCG is synthesized by the placenta very early in pregnancy and can be detected in the blood 8-11 days after conception. Higher levels of hCG after 11 weeks of gestation may suggest a higher chance of the baby having Down syndrome. On the other hand, low levels indicate an increased risk for trisomy 18.

PAPP-A is a protein produced by the placenta that is needed for the implantation and maintenance of a healthy placenta (afterbirth). Low levels of PAPP-A before the 14th week of pregnancy suggest an increased risk of fetal chromosomal abnormalities.
