Dual Marker Test Twin Pregnancy

Report Delivery Time: Next Day

Recommended Gender: Female

Sample Type: Blood

The Dual Marker Test for Twin Pregnancy is a crucial prenatal screening tool used during the first trimester to assess the risk of chromosomal abnormalities like Down syndrome. Specifically designed for twin pregnancies, it analyzes maternal blood for key markers to support early fetal health evaluation.

The Dual Marker Test Twin Pregnancy is a specialized prenatal screening test recommended for expecting mothers carrying twins. Conducted during the first trimester (usually between 11 to 13 weeks of gestation), this test evaluates the risk of chromosomal abnormalities, including Trisomy 21 (Down syndrome) and Trisomy 18 (Edwards syndrome).

This test measures the levels of Free Beta hCG and PAPP-A (Pregnancy-Associated Plasma Protein A) in the mother’s blood, which, when analyzed alongside ultrasound data (nuchal translucency scan) and maternal age, helps estimate the likelihood of genetic disorders.

In twin pregnancies, early screening becomes even more important due to increased risks. The Dual Marker Test offers non-invasive, early-stage risk assessment that aids healthcare providers in determining whether further testing (like NIPT or amniocentesis) is needed.


Parameters Covered:

  • Free Beta hCG (Human Chorionic Gonadotropin): Measures hormone levels associated with pregnancy; abnormal levels may indicate chromosomal anomalies.

  • PAPP-A (Pregnancy-Associated Plasma Protein A): A protein involved in placental development; low levels may be linked to genetic abnormalities.


Why is the Test Important?

  • Detects potential chromosomal abnormalities early in twin pregnancies.

  • Helps determine the need for advanced diagnostic tests.

  • Offers peace of mind through early fetal health insights.

  • Supports timely medical decisions during high-risk pregnancies.


Who Should Take This Test?

  • All pregnant women expecting twins, ideally between 11–13 weeks of pregnancy.

  • Women with a family history of genetic conditions.

  • Mothers over the age of 35, where risk of chromosomal issues increases.

  • Those who want early screening for fetal health.


Dual Marker Test Twin Pregnancy Procedure & Preparation:

  • Sample Type: Blood sample

  • Fasting Required: No fasting required

  • Preparation: No special preparation is needed

  • The test may be paired with an ultrasound scan (NT scan) for greater accuracy.


Understanding the Results:

The results of the Dual Marker Test for twin pregnancy are not diagnostic, but rather risk assessments. A “screen positive” result indicates a higher risk and may require follow-up with more definitive tests like NIPT (Non-Invasive Prenatal Testing) or amniocentesis. A “screen negative” result means the risk is low but not entirely ruled out.
