NIPT (TWINS)*

The NIPT Twin Test is an advanced prenatal screening designed specifically for twin pregnancies to assess the risk of genetic abnormalities in unborn babies. It is a specialized form of Non-Invasive Prenatal Testing (NIPT) that analyzes fetal DNA present in the mother’s blood.

This test is gaining popularity because it is safe, highly accurate, and non-invasive, making it a preferred option for expectant mothers carrying twins.

What is the NIPT Twin Test?

The NIPT Twin Test is a blood test that evaluates the risk of chromosomal abnormalities in both fetuses during a twin pregnancy.

It works by analyzing cell-free fetal DNA (cff DNA) circulating in the mother’s bloodstream. The test can detect conditions such as:

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

Although slightly more complex than single-pregnancy NIPT, it still provides valuable early insights into fetal health.

Why is the NIPT Twin Test Recommended?

Twin pregnancies are considered higher risk, and this test helps in early screening without invasive procedures.

Common reasons for recommendation:

• Twin pregnancy with advanced maternal age (35+)
• Abnormal findings in ultrasound
• Family history of genetic disorders
• Previous pregnancy with chromosomal abnormalities
• Need for early and safe genetic screening

What is the NIPT Twin Test Price in Delhi

The NIPT Twin Test price in Delhi can vary depending on the location of the diagnostic centre. The average price in Delhi is INR 12000 to INR 15000

Preparation for the NIPT Twin Test

• No fasting is required
• You can eat and drink normally
• Inform your doctor about your Medical history, IVF pregnancy (if applicable) or any Previous complications

What is the procedure for the NIPT twin test?

• A blood sample is collected from the mother’s arm
• The sample is sent to a specialized laboratory
• Fetal DNA fragments are extracted and analyzed
• Advanced techniques are used to screen for chromosomal abnormalities

Benefits of the NIPT Twin Test

• Completely non-invasive and safe
• High accuracy compared to traditional screening
• Early detection (from 10 weeks of pregnancy)
• Reduces the need for invasive tests like amniocentesis
• Provides peace of mind for parents

What are the Limitations of the NIPT Twin Test

• Slightly lower accuracy compared to singleton NIPT
• Cannot always determine which twin is affected
• Not a diagnostic test (confirmation may be needed)
• Limited detection for some rare conditions

Who Should Take the NIPT Twin Test?

• Women carrying twins (dichorionic or monochorionic)
• High-risk pregnancies
• Couples seeking early reassurance about fetal health
• Pregnant women are advised by their doctor to undergo genetic screening

Conclusion

The NIPT Twin Test is a modern, reliable, and non-invasive screening tool designed specifically for twin pregnancies. It allows early detection of genetic risks while ensuring safety for both mother and babies.

Although it is not a confirmatory test, it plays a crucial role in early screening and decision-making, helping parents and doctors plan appropriate care during pregnancy.

FAQs

What is the NIPT Twin Test, and how is it different from a regular NIPT?

The NIPT Twin Test is a specialized version of Non-Invasive Prenatal Testing (NIPT) designed specifically for twin pregnancies. While a standard NIPT evaluates genetic risks in a single fetus, the twin version analyses cell-free fetal DNA from both babies present in the mother’s blood. Because two fetuses contribute DNA, the analysis is more complex, and although it remains highly accurate, interpretation requires advanced laboratory techniques.

What is the NIPT Twin test price in Delhi?

The NIPT Twin test price in Delhi usually ranges between ₹18,000 and ₹25,000, depending on the laboratory, technology used, and whether you choose a basic or expanded screening panel. 

When should the NIPT Twin Test be done during pregnancy?

The test can typically be performed from the 10th week of pregnancy onwards, when there is sufficient fetal DNA in the mother’s bloodstream. Early testing allows timely detection of potential chromosomal abnormalities and helps in better pregnancy management.

How is the NIPT Twin Test performed?

The procedure is very simple and non-invasive. A small blood sample is collected from the mother’s arm, and the sample is then sent to a specialised laboratory where fetal DNA fragments are analyzed using advanced genetic testing methods to assess the risk of chromosomal abnormalities in both fetuses.

Is the NIPT Twin Test safe for both babies?

Yes, the test is completely safe because it only involves drawing blood from the mother. Unlike invasive procedures such as amniocentesis, there is no risk of miscarriage or harm to either fetus, making it a preferred screening option for twin pregnancies.

How accurate is the NIPT Twin Test?

The NIPT Twin Test is highly accurate, especially for detecting conditions like Down Syndrome. However, due to the presence of two fetuses, the accuracy may be slightly lower than in singleton pregnancies, and results are reported as risk levels rather than definitive diagnoses.

What conditions can the NIPT Twin Test detect?

The test primarily screens for major chromosomal abnormalities such as Down syndrome (Trisomy 21), Trisomy 18, and Trisomy 13. 

Can the test identify which twin has a genetic problem?

In most cases, the NIPT Twin Test cannot determine which twin is affected if a high-risk result is detected. It only indicates that one or both fetuses may be at risk, and further diagnostic testing is required for confirmation.

How long does it take to get the results?

The results are generally available within 5 to 10 days, depending on the laboratory and testing technology used. 

Do I need any special preparation before the test?

No special preparation is required. You can eat and drink normally before the test. However, it is important to inform your doctor about your medical history, IVF pregnancy, or any complications.

What happens if the NIPT Twin Test result is high risk?

If the test result indicates a high risk for a chromosomal abnormality, your doctor may recommend confirmatory diagnostic procedures such as amniocentesis or chorionic villus sampling (CVS) to make a definitive diagnosis.

Can I book the NIPT Twin Test near me in Delhi?

Yes, you can book the test through reputed diagnostic labs or online healthcare platforms by searching “NIPT Twin test near me” or “how to book test near me,” making the process convenient and accessible.

What are the main benefits of the NIPT Twin Test?

The key benefits include early detection of genetic risks, high accuracy compared to traditional screening methods, complete safety for both babies, and reduced need for invasive procedures, providing reassurance to expectant parents.
