NIPT tests are highly accurate for detecting chromosomal abnormalities such as XXY (Klinefelter syndrome), with accuracy rates often exceeding 99%. However, they are screening tests, not diagnostic, meaning any positive result should be confirmed with further diagnostic testing like amniocentesis or CVS.
