Why You Should Not Miss Your NT Scan and Double Marker Test During Pregnancy?

Pregnancy is a transformative and overwhelming journey for every parent. Along with the joy and excitement, it’s crucial to prioritize the health and well-being of the mother and the baby. Regular prenatal check-ups, tests and scans play a key role in ensuring a healthy pregnancy. Among these tests, the NT (Nuchal Translucency) scan and Double Marker test are of utmost importance.

In this blog, we will delve into the importance of these tests in ensuring a smooth and risk-free pregnancy and why you shouldn’t skip them.

The NT scan, also known as the nuchal translucency scan, is a safe, non-invasive specialised ultrasound performed between 11 and 14 weeks of pregnancy. This test measures the thickness of the fluid-filled space at the back of the baby’s neck. The importance of the NT scan lies in its ability to screen for Down syndrome (trisomy 21) and other chromosomal abnormalities such as trisomy 18 and trisomy 13.

On the other hand, the double marker test is a blood test performed between 9 and 13 weeks of pregnancy. The test measures the levels of two specific substances in the mother’s blood, namely pregnancy-associated plasma protein-A (PAPP-A) and human chorionic gonadotropin (hCG). The levels of these hormones, along with other factors like the mother’s age, help assess the risk of certain chromosomal abnormalities. This test is a simple and safe procedure and the results are typically combined with the NT scan finding to provide a more accurate risk assessment.

Importance of NT Scan and Double Marker Test During Pregnancy:

01. Early Detection and Risk Assessment:

The NT scan and double marker test are effective screening tools for genetic anomalies like Down syndrome, Edwards syndrome, and Patau syndrome. During this ultrasound, the fetus will also be evaluated for major structural anomalies. By undergoing these tests, you increase your chance of identifying any potential structural or chromosomal problems early on, allowing you to make an informed decision and seek the support you need.

02. Treatment and Intervention Options:

If the NT scan and double marker test detect any abnormalities, it allows you and your doctor to explore treatment and intervention options. Early detection allows for better management of certain conditions. It also gives you the time to educate yourself about the condition, consult specialists and make informed decisions about the unborn baby’s future.

03. Comprehensive Evaluation of Pregnancy Health:

These tests not only evaluate the health of the fetus but also your pregnancy as a whole. They aid in identifying some disorders that may call for more monitoring or care for the mother, like preeclampsia or gestational diabetes. With these tests done, you can promote an overall healthier pregnancy.

04. Awareness and Preparation:

Knowledge is power, particularly when it comes to your pregnancy. The NT scan as well as the double marker test both offer insightful data regarding your baby’s growth and any possible risks. With this knowledge, you may educate yourself, seek out medical advice, and prepare yourself mentally and emotionally for any challenges that may lie ahead.


Prenatal care is essential for a healthy pregnancy and a positive outcome for the mother and the unborn child. The early detection of structural and chromosomal abnormalities is made possible with the help of the above-mentioned scans and tests. These are valuable tools that enable prompt interventions and support. By undergoing these tests, expectant parents can proactively manage any risks, make informed decisions, and guarantee the best start to their baby’s life.
