Can Twins Be Missed on Non-Invasive Prenatal Testing (NIPT)?

Learn why twins, especially identical ones, can sometimes be missed on NIPT and why ultrasound is the most reliable method to detect multiples.

Yes, twins can be missed on NIPT (Non-Invasive Prenatal Testing), especially if the twins are monozygotic (identical) since they share the same DNA. However, it's relatively rare. NIPT is primarily designed to screen for genetic abnormalities rather than confirm multiples. Traditional ultrasound remains the most reliable method for determining the presence of twins early in pregnancy. If there's any doubt or inconsistency in NIPT results, further evaluation through ultrasound is usually recommended.

FAQs & Answers

  1. Why can twins be missed on NIPT? Twins, especially monozygotic (identical) twins, can be missed on NIPT because they share the same DNA, making it challenging for the test to differentiate two fetuses in genetic screening.
  2. Is ultrasound more reliable than NIPT for detecting twins? Yes, ultrasound is the most reliable method to detect the presence of twins early in pregnancy, as NIPT primarily screens for genetic abnormalities rather than confirming multiple pregnancies.
  3. What should be done if NIPT results are unclear regarding multiples? If NIPT results are inconsistent or raise doubts about multiple pregnancies, further evaluation with traditional ultrasound is recommended for accurate detection.
