The Dual Marker Test is a non-invasive prenatal screening typically performed during the first trimester of pregnancy, usually between 9 to 13 weeks. It is especially useful in detecting the risk of Down syndrome (Trisomy 21), Edward syndrome (Trisomy 18), and other chromosomal abnormalities.

Unlike diagnostic tests that carry potential risks, the dual marker test is completely safe for both the mother and the baby, providing early, accurate, and reliable data to support informed decisions.

1. PAPP-A (Pregnancy-Associated Plasma Protein A)

PAPP-A is a protein produced by the placenta in early pregnancy. Abnormal levels of PAPP-A may indicate a higher risk of chromosomal disorders or complications related to fetal growth.

2. Free Beta hCG (Human Chorionic Gonadotropin)

This is a hormone that is also produced by the placenta. In the context of the dual marker test, unusually high or low levels of free beta hCG can signal a possible chromosomal condition, including Down syndrome.

Together, these markers—combined with ultrasound measurements like Nuchal Translucency (NT)—can provide a clearer picture of the baby’s genetic health.The Dual Marker Test is a proactive step toward ensuring a healthy pregnancy and peace of mind for expecting parents. With just a small blood sample, you gain powerful insight into your baby’s development and can take early action if necessary.
