Yes, a baby with a negative Non-Invasive Prenatal Testing (NIPT) can still have Down syndrome. While NIPT is a highly accurate screening tool, it is not definitive. False negatives, although rare, can occur. It's important for expectant parents to discuss the results with a healthcare provider, who may recommend further diagnostic testing for a more conclusive determination.

FAQs & Answers

  1. How accurate is NIPT in detecting Down syndrome? NIPT has a high accuracy rate, often above 99% for detecting Down syndrome; however, it is a screening test and not definitive, which means false negatives can occur.
  2. What should I do if my NIPT results are negative but I still have concerns? Discuss your concerns with your healthcare provider, who may recommend further diagnostic tests such as chorionic villus sampling (CVS) or amniocentesis to confirm the fetal condition.
  3. What causes false negative results in NIPT? False negatives can arise due to low fetal DNA fraction in the maternal blood sample, mosaicism, or technical limitations of the test.
