Understanding Double Marker Test and Quadruple Marker Test During Pregnancy

Picture87

When expecting a baby, it is natural for parents to want assurance about their child’s health. Two vital prenatal screening tests, the double marker test and quadruple marker test, offer valuable insights into the baby’s well-being during different stages of pregnancy.

What Are Double and Quadruple Marker Tests?

Double Marker Test: Also known as maternal serum screening, this test is typically conducted in the first trimester to assess the risk of neurological disorders such as Down syndrome and Edward’s syndrome. It analyzes free beta HCG and PAPPA-A markers in the mother’s blood.

Quadruple Marker Test: Administered in the second trimester, the quadruple marker test evaluates four crucial pregnancy hormones: alpha-fetoprotein, human chorionic gonadotropin (hCG), inhibin A, and unconjugated estriol (uE3). It helps identify genetic defects and neurological issues in the fetus.

When Are These Tests Required?

Double Marker Test: Recommended between 11 and 14 weeks of pregnancy.

Quadruple Marker Test: Conducted during the second trimester.
