The Double Marker Test, also known as the Dual Marker Test or Maternal Serum Screening for the first trimester, is a crucial prenatal screening tool offered to expectant mothers.
It's performed in the first trimester of pregnancy, typically between 10 and 14 weeks.
What the Test Measures
The "double markers" are two specific substances measured in the mother's blood, which are produced by the baby and the placenta:
Free Beta Human Chorionic Gonadotropin (Free β-hCG): This is a hormone produced by the placenta.
Pregnancy-Associated Plasma Protein-A (PAPP-A): This is a protein produced by the placenta.
Purpose and Importance
The primary goal of the Double Marker Test is to screen for the risk of the fetus having certain chromosomal abnormalities:
Down Syndrome (Trisomy 21): The presence of an extra copy of chromosome 21.
Edwards Syndrome (Trisomy 18): The presence of an extra copy of chromosome 18.
