Double Marker Test In Delhi

Overview of the Double Marker Test

Test Overview

The Double Marker Test is a prenatal screening test performed during the first trimester, usually between 9 and 13 weeks of pregnancy. It helps assess the risk of chromosomal abnormalities in the fetus, particularly Down syndrome (Trisomy 21) and Edwards syndrome (Trisomy 18). The test measures the levels of two key biomarkers in the mother’s blood: free Beta-human Chorionic Gonadotropin (β-hCG) and Pregnancy-Associated Plasma Protein-A (PAPP-A). Abnormal levels of these markers may indicate a higher risk of fetal genetic disorders.

The Double Marker Test does not provide a definitive diagnosis but serves as a screening tool to identify pregnancies that may require further evaluation. If the results suggest an increased risk, additional diagnostic tests such as Non-Invasive Prenatal Testing (NIPT), amniocentesis, or chorionic villus sampling (CVS) may be recommended for confirmation. This test is often conducted alongside ultrasound-based nuchal translucency (NT) screening to enhance accuracy. It is particularly recommended for women over 35 years of age, those with a family history of genetic disorders, or individuals with high-risk pregnancy factors.

Tests Included in Double Marker Test in Delhi

The double marker test in pregnancy, also known as the dual marker test or dual test in pregnancy, involves analyzing two key components in the mother's blood.

• Pregnancy-Associated Plasma Protein A (PAPP-A): PAPP-A is a protein secreted by the placenta during pregnancy. Lower-than-normal levels of this protein may indicate a higher risk of chromosomal abnormalities, such as Down syndrome or Edward's syndrome.
• Free Beta-Human Chorionic Gonadotropin (β-hCG): β-hCG is a hormone produced by the placenta that plays a crucial role in sustaining pregnancy. Elevated levels of β-hCG can be associated with an increased risk of conditions like Down syndrome.

By combining the results of these two markers with factors such as the mother's age, gestational age, and nuchal translucency measurements, the dual marker test calculates a risk score. This risk assessment helps identify pregnancies that may benefit from further diagnostic tests, such as amniocentesis or chorionic villus sampling.

Signs You Need to Get Double Marker Test Done

The Double Marker Test is typically recommended for pregnant women as part of routine prenatal screening, but certain factors may indicate a stronger need for the test. Here are some signs and conditions that may warrant taking the Double Marker Test:

• Advanced Maternal Age – Women aged 35 and above are at a higher risk of chromosomal abnormalities in their babies, making this test particularly important.
• Abnormal Ultrasound Findings – If a nuchal translucency (NT) scan or other early pregnancy ultrasounds indicate potential concerns, doctors may recommend this test.
• Family History of Genetic Disorders – Women with a family history of Down syndrome, Edwards syndrome, or other genetic abnormalities should consider screening.
• Previous Pregnancy Complications – If a woman has had a previous pregnancy with chromosomal abnormalities or miscarriage due to genetic conditions, this test may be advised.
• Exposure to Harmful Substances – Pregnant women who have been exposed to radiation, certain medications, chemicals, or infections that could affect fetal development may need additional screening.
• Abnormal First-Trimester Blood Tests – If routine prenatal blood tests indicate potential risks, the Double Marker Test may help in further assessment.
• High-Risk Pregnancy Factors – Women with chronic conditions like diabetes, hypertension, or autoimmune disorders may be advised to undergo this test for additional monitoring.

If any of these factors apply, consulting a doctor about the Double Marker Test can help ensure early detection and better prenatal care.

Test Requirements

The Double Marker Test is a simple blood test that requires minimal preparation. Below are the key requirements:

• Timing: It is typically performed between 9 to 13 weeks of pregnancy, often in conjunction with a nuchal translucency (NT) ultrasound.
• Fasting: Generally, fasting is not required, but some healthcare providers may advise it based on individual cases.
• Sample Collection: A blood sample is drawn from the mother's arm for analysis.
• Medical History: Inform your doctor about any pre-existing health conditions, medications, or previous pregnancy complications, as these factors may influence the interpretation of results.
• Doctor’s Recommendation: The test is usually recommended for women over 35 years of age, those with a family history of genetic disorders, or individuals with high-risk pregnancy factors.

The results of the Double Marker Test are analyzed alongside ultrasound findings to provide a more accurate risk assessment for chromosomal abnormalities. If the results indicate an increased risk, additional diagnostic tests such as Non-Invasive Prenatal Testing (NIPT), amniocentesis, or chorionic villus sampling (CVS) may be recommended.

Price of the Double Marker Test in Delhi

Double Marker Test  Price in Different Cities

The cost of the Double Marker Test varies depending on factors such as the location, diagnostic centre, healthcare provider, and additional services offered.

• Location: Diagnostic centres in metropolitan cities or private hospitals might charge more than smaller clinics in rural or less densely populated areas.
• Package Deals: Many diagnostic centres offer bundled packages that include the Double Marker Test alongside other prenatal tests (e.g., Quadruple Marker Test, Nuchal Translucency Scan, etc.), which could influence the overall cost. These packages may offer a discounted rate when tests are purchased together.
• Type of Test: Some labs may offer advanced versions of the Double Marker Test that include extra features or higher accuracy, which may lead to a slightly higher price.

To get the most accurate and updated details about the double marker test price, it’s a good idea to check with local clinics or trusted online medical services. Many platforms, like Apollo 24|7, make it easy to book the test and also share pricing details upfront, so you know what to expect.

Reports of the Double Marker Test

The Double Marker Test provides risk scores based on your blood levels and other factors, such as maternal age. These scores are usually presented as ratios, like 1 in 1000 or 1 in 50. Here’s how to interpret these results:

Important Note:

• The Double Marker Test is a screening test, not a diagnostic test.
• Always discuss the results with your doctor to understand the next steps.

What to Do to Get Normal Readings for Double Marker Test? 

While the Double Marker Test primarily assesses genetic risks and is not influenced by lifestyle factors, maintaining overall maternal health can contribute to optimal pregnancy outcomes. Here are some key steps to support a healthy pregnancy and possibly improve test accuracy:

• Eat a Balanced Diet – Consume nutrient-rich foods like leafy greens, whole grains, lean proteins, and dairy to support fetal development.
• Take Prenatal Vitamins – Ensure adequate folic acid, iron, and calcium intake to reduce the risk of neural tube defects and other complications.
• Stay Hydrated – Drink plenty of water to support proper circulation and overall maternal health.
• Avoid Harmful Substances – Avoid alcohol, smoking, and drugs, as they can increase pregnancy risks and affect fetal health.
• Manage Stress – Practice meditation, deep breathing, or prenatal relaxation techniques to reduce stress, which can impact overall pregnancy well-being.
• Exercise Regularly – Engage in moderate physical activity like walking or prenatal yoga to promote circulation and overall health.
• Follow Medical Advice – Attend all prenatal checkups and follow your doctor's guidance regarding screening tests and lifestyle recommendations.
