What is the Double Marker Test?

The Double Marker Test is a prenatal blood screening test conducted during the first trimester of pregnancy (between 11 and 14 weeks). It is used to detect chromosomal abnormalities in the fetus, such as:

• Down Syndrome (Trisomy 21)
• Trisomy 18 (Edwards Syndrome)
• Trisomy 13 (Patau Syndrome)

The test measures levels of two important markers in the mother’s blood:

1. Free Beta-hCG (Human Chorionic Gonadotropin): A hormone produced during pregnancy.
2. PAPP-A (Pregnancy-Associated Plasma Protein A): A protein produced by the placenta.

Abnormal levels of these markers can indicate chromosomal abnormalities or genetic disorders in the developing baby.

Why is the Double Marker Test Important?

• Early Detection of Genetic Disorders: Helps assess the risk of chromosomal abnormalities in the fetus.
• Safer Pregnancy Management: Allows doctors to suggest further diagnostic tests like NIPT (Non-Invasive Prenatal Testing), CVS (Chorionic Villus Sampling), or Amniocentesis if needed.
• Informed Decisions: Gives expecting parents the knowledge to take timely medical advice.
• Peace of Mind: Normal results reassure parents about the baby’s development.

Who Should Get the Double Marker Test?

While doctors may recommend it for all pregnant women, it is especially important for:

• Women aged 35 years and above (higher risk of chromosomal issues).
• Pregnant women with a family history of genetic disorders.
• Mothers with previous abnormal pregnancies or miscarriages.
• Women with exposure to infections, radiation, or harmful substances during early pregnancy.

How is the Double Marker Test Done?

The Double Marker Test is a simple blood test:

1. A small blood sample is taken from the mother.
2. The sample is analyzed in the lab for Free Beta-hCG and PAPP-A levels.
3. The results are combined with ultrasound findings (NT Scan – Nuchal Translucency Test) for more accuracy.

It is a non-invasive and risk-free test for both mother and baby.

Normal Range of Double Marker Test

• Free Beta-hCG:
• High levels → May indicate a higher risk of Down syndrome.
• Low levels → May indicate risk of Edwards syndrome or Patau syndrome.

  PAPP-A:

• Low levels are associated with chromosomal abnormalities.
• Since values vary depending on gestational age and individual health, doctors interpret results along with ultrasound scans.
