Introduction
Pregnancy is an exciting journey, but it also comes with many questions and concerns about the health of both the mother and the baby. One important test that helps assess the baby’s risk of certain genetic conditions is the Dual Marker Test. If you're expecting or planning a pregnancy, understanding this test can help you make informed decisions.
What is the Dual Marker Test?
The Dual Marker Test is a simple blood test performed during the first trimester of pregnancy (between 9 to 13 weeks). It measures two key substances in the mother’s blood:
1. Pregnancy-Associated Plasma Protein-A (PAPP-A): A protein produced by the placenta.
2. Free Beta Human Chorionic Gonadotropin (Free β-hCG): A hormone produced during pregnancy.
Along with an ultrasound scan (nuchal translucency scan), this test helps assess the risk of chromosomal abnormalities in the baby, such as Down syndrome (Trisomy 21), Edwards syndrome (Trisomy 18), and Patau syndrome (Trisomy 13).
Why is the Dual Marker Test Done?
The test is not mandatory, but doctors recommend it for:
- Women aged 35 and above (higher risk of chromosomal abnormalities).
- A family history of genetic disorders.
- Previous pregnancies with chromosomal abnormalities.
- Women with diabetes or other high-risk conditions.
It is a screening test, not a diagnostic one, meaning it only estimates risk. If the results show a high risk, further tests like NIPT (Non-Invasive Prenatal Testing) or amniocentesis may be advised.
What Does the Dual Marker Test Detect?
The test evaluates the likelihood of:
- Down syndrome (Trisomy 21): Causes intellectual disability and developmental delays.
- Edwards syndrome (Trisomy 18): A severe condition affecting multiple organs.
- Patau syndrome (Trisomy 13): A rare disorder causing serious birth defects.
How is the Test Performed?
1. Blood Sample Collection: A small blood sample is taken from the mother’s arm.
2. Ultrasound Scan: Measures the baby’s nuchal translucency (fluid at the back of the neck).
3. Combined Report: The blood test and ultrasound results are analysed together to assess risk.
The test is safe, non-invasive, and painless, with no risk to the baby.
Dual Marker Test Cost in India
The cost varies depending on the city and lab, but generally ranges between ₹2,000 to ₹4,500. Some factors affecting the price include:
- Location (Metro cities may charge more).
- Lab facility (Private vs. government hospitals).
- Additional tests (If combined with other screenings).
At Apollo 24|7, you can book the test at a competitive price with reliable results.
When Should You Take the Test?
The ideal time is between 9 to 13 weeks of pregnancy. Taking it later may reduce accuracy.
Understanding the Results
Results are given as a risk ratio, such as 1 in 1,000 (low risk) or 1 in 100 (high risk).
- Low Risk: No further testing is usually needed.
- High Risk: Your doctor may recommend NIPT, CVS (Chorionic Villus Sampling), or amniocentesis for confirmation.
Remember, a high-risk result does not mean the baby has a disorder—only that more tests are needed.
Tips for a Healthy Pregnancy
While the Dual Marker Test helps assess risks, maintaining a healthy pregnancy is crucial:
- Eat a Balanced Diet: Include fruits, vegetables, whole grains, and proteins.
- Take Prenatal Vitamins: Folic acid, iron, and calcium are essential.
- Stay Hydrated: Drink plenty of water.
- Avoid Smoking & Alcohol: Harmful for the baby’s development.
- Exercise Moderately: Walking, yoga, or light exercises help.
- Regular Check-ups: Follow your doctor’s advice for scans and tests.
Conclusion
The Dual Marker Test is a valuable screening tool that helps expectant mothers understand potential risks early in pregnancy. While it may cause some anxiety, knowing the results can help you and your doctor take the best steps for a healthy pregnancy.
If you’re in your first trimester, consult your doctor about whether this test is right for you.
