What is Double Marker Test - First Trimester in Mysore?

Dual marker test is a first trimester screening test advised to all pregnant women, for assessing the risk of certain genetic abnormalities in the fetus. It can be conducted between the 9th-13th week of pregnancy, but the ideal sampling time is between 11-13^th week. The term “Dual Marker” means two markers are tested -Free beta human chorionic gonadotropin ( fβ-HCG ) & Pregnancy-Associated Plasma Protein (PAPP-A ). It helps in evaluating the risk of a fetus developing Trisomy 21 (Down syndrome) and Trisomy 13/18 syndrome. As these genetic conditions lead to mental retardation and other medical illnesses which might impact the vital organs of the fetus, it is extremely crucial for all pregnant women to undergo this investigation.
