#asktheexpert I have done NT scan and Double marker test at 13 weeks. NT scan report is good as well as Double marker test report is Low risk. But calculated age risk is 1:119 as my age is 38. Should I go for NIPT test or wait for anamoly scan.??

A. Given your age and the results of your NT scan and double marker test, it is understandable to consider further testing. Here’s a brief overview to help you decide: ### **1. **NIPT (Non-Invasive Prenatal Testing):** - **Purpose:** NIPT is a highly accurate screening test that assesses the risk of certain genetic conditions, such as Down syndrome (trisomy 21), trisomy 18, and trisomy 13, by analyzing fetal DNA in the mother's blood. - **Accuracy:** It is more accurate than traditional screening tests and can provide more detailed information about your baby's risk of chromosomal abnormalities. - **Recommendation:** Given your age (38), which is considered advanced maternal age, and the fact that your calculated age risk is 1 in 119, NIPT is often recommended to provide more clarity and reduce uncertainty. ### **2. **Anomaly Scan (Detailed Ultrasound):** - **Purpose:** The anomaly scan, typically performed between 18 and 22 weeks of pregnancy, checks for structural abnormalities in the fetus. It provides detailed imaging and can detect a range of potential issues. - **Timing:** This scan is a crucial part of prenatal care, but it may not provide information about chromosomal abnormalities like NIPT. ### **Decision-Making:** - **If you want more detailed information about the risk of chromosomal abnormalities before the anomaly scan:** Opt for the NIPT. It offers a higher level of accuracy and peace of mind regarding the risk of specific genetic conditions. - **If you prefer to wait until the anomaly scan:** This scan will provide information about structural issues, and you can still consider NIPT based on the results and any additional concerns that arise. ### **Consult with Your Healthcare Provider:** - **Personalized Advice:** Discuss with your healthcare provider to determine the best course of action based on your specific situation, risk factors, and any additional concerns you might have. They can provide personalized recommendations and guide you through the next steps. Choosing between NIPT and waiting for the anomaly scan depends on your preference for early, detailed information versus waiting for structural insights later in the pregnancy.
