The Double Marker Test is a screening test done during pregnancy to check the risk of chromosomal issues like Down syndrome. It measures two substances in the mother's blood: PAPP-A (pregnancy-associated plasma protein A) and free ?-hCG (human chorionic gonadotropin). The cost can vary depending on the hospital and city. Knowing the normal range helps in early detection and further diagnosis. The test is safe, with very minimal risks like slight discomfort during the blood sample collection.
What is the Double Marker Test?
The Double Marker Testis a prenatal screening test performed during the 10th to 14th week of pregnancy. It assesses the risk of chromosomal abnormalities, such as Down syndrome, and detects potential hormonal imbalances in the developing fetus. The test measures two key substances in the mother's blood:
- Human Chorionic Gonadotropin (hCG)
- Pregnancy-Associated Plasma Protein-A (PAPP-A)
Abnormal levels of these substances may indicate an increased risk of chromosomal conditions or developmental issues in the fetus. This test is optional and is not a diagnostic tool but rather a screening method to identify the need for further testing.
Why is the Double Marker Test Done?
The first-trimester screening (dual marker test and NT scan) is optional. But, if you're over 35 or have a family history of specific illnesses, the screening (and others like the cell-free DNA test) is suggested.
Understanding that the result merely tells you if you have a higher chance of trisomies is essential. It does not determine whether or whether your baby has any abnormalities.
When deciding whether or not to have a double marker test, consider what the findings might imply to you in the long term.
- Does learning about probable anomalies make you feel better or worse?
- Would you want to undergo more intrusive testing if the results indicated a higher risk?
- Would the findings affect how you manage your pregnancy?
It all depends on personal choice and individual medical history.

The double marker test is a basic blood test that does not require fasting. Unless otherwise indicated by your doctor, you can eat or drink normally before your visit. The blood sample is analyzed to measure hCG and PAPP-A levels.

Why is a Double Marker Test in Pregnancy Conducted?
The test helps to:
- Identify potential chromosomal abnormalities such as trisomy 21 (Down syndrome), trisomy 13, and trisomy 18.
- Provide early information to guide further testing and decision-making.
- Offer insights into the health and development of the fetus during early pregnancy.
This test allows parents and healthcare providers to plan additional diagnostic tests or treatments if necessary.
How Do I Understand My Double Marker Test Results?
- Low Risk (Negative): Indicates that your baby is unlikely to have chromosomal abnormalities. No further testing may be required unless other factors (age, family history) are present.
- High Risk (Screen-Positive): This indicates a higher likelihood of abnormalities. For confirmation, additional tests, such as Non-Invasive Prenatal Testing (NIPT), amniocentesis, or chorionic villus sampling, may be recommended.
It's important to note that this test does not screen for all possible conditions, If your screening results show that you are at moderate or high risk for abnormalities ("screen-positive"), you should consult a genetic counselor to learn more.
How Much Does the NT Scan and Double Marker Test Cost in India?
The price of an NT scan and double marker test varies depending on the location and diagnostic facility. Medicover Hospitals aims to provide affordable and accurate diagnostic services. For detailed pricing, contact your nearest Medicover branch.
Are There Any Risks or Side Effects of the Double Marker Test?
The Double Marker Test is entirely safe, non-invasive, and risk-free. It involves drawing a small amount of blood, making it suitable for all expectant mothers.
When is the Double Marker Test Needed?
The Double Marker Test is typically recommended in the early stages of pregnancy to:
- Screen for Down syndrome and other chromosomal abnormalities.
- Assess the risk of certain birth defects, especially during the first trimester.
- Identify if further diagnostic tests (like amniocentesis) are needed for a more thorough evaluation.
- Monitor high-risk pregnancies, especially in women over 35 years of age or with a family history of genetic disorders.
Who Should Take the Double Marker Test?
The Double Marker Test is for:
- Pregnant women in their first trimester (11 to 14 weeks) to screen for chromosomal abnormalities.
- Women over 35 years old who have a higher risk of chromosomal disorders.
- Women with a family history of genetic conditions or previous pregnancies with complications.
- Pregnant women with abnormal ultrasound or screening results who require further evaluation.
How Should I Prepare for the Double Marker Test?
For the Double Marker Test, there is generally no special preparation required, but consider the following:
- Fasting is not required, but it is recommended to stay hydrated for easier blood collection.
- If you are taking any medications, inform your doctor as they may affect the test results.
- Wear comfortable clothing for ease of blood collection, usually from your arm.
What Type of Sample is Collected for the Double Marker Test and How?
The Double Marker Test requires a blood sample:
- A healthcare provider will clean the skin where the needle will be inserted, typically in the inner elbow or back of your hand.
- A small needle is used to draw a small amount of blood (this takes about 5-10 minutes).
- The blood is then sent to the lab for analysis to measure the levels of PAPP-A and hCG, which help assess the risk of chromosomal abnormalities.
Are There Other Ways to Collect the Sample for the Double Marker Test?
The Double Marker Test typically requires a blood sample, and there are no alternative collection methods for this test.
How Long Does the Double Marker Test Take?
- The blood collection for the Double Marker Test takes about 5-10 minutes.
- Results usually take 2-3 days after the blood is sent to the lab.
When Will I Get My Double Marker Test Results?
- Results for the Double Marker Test are typically available within 12 to 24 hours after the sample is collected.
- You will receive the results via WhatsApp or as a printed copy from your healthcare provider.
What Should I Do After Getting My Double Marker Test Results?
- Consult your doctor to discuss the results. If the results suggest a higher risk, further testing, such as amniocentesis or NIPT (Non-Invasive Prenatal Testing), may be recommended.
- Follow-up care or additional screening may be needed to assess the health of the baby and the pregnancy.
Is the Double Marker Test Painful?
- The Double Marker Test involves a simple blood draw.
- It is generally not painful, but you may feel a mild prick or sting when the needle is inserted.
- Any discomfort is usually temporary.
What are the Factors Affecting the Double Marker Test Cost?
- The cost can vary based on location and the lab
- Technology and methodology used in the test can affect pricing.
- Additional services such as follow-up consultations or diagnostic tests may also influence the final cost.

No, the test is optional, and not all women choose to have it. It is essential to discuss the risks and benefits of the test with your healthcare provider before deciding whether or not to have it.
Yes, the double marker test is completely safe for the baby as it only requires a maternal blood sample. Medicover Hospitals ensures a safe and accurate testing process.
No, the test does not reveal the baby's gender. Its purpose is to assess the risk of chromosomal abnormalities, not to determine the baby's sex. Visit Medicover Hospitals for reliable testing services.
The cost of a double marker test is approximately Rs. 950, but it may vary based on location and specific requirements. Contact Medicover Hospitals for detailed pricing.
