Video transcript

NIPT tests can be wrong due to various factors, including low fetal DNA fraction, maternal DNA contamination, or technical errors. To reduce the chance of inaccuracies, ensure the test is conducted at the recommended gestational age (10 weeks or later) and consider repeat testing or follow-up diagnostic tests (like amniocentesis) if results are unexpected. Discussing possible outcomes and limitations with a healthcare professional before testing is important.

Questions and answers

  1. What factors cause NIPT test results to be incorrect?
