Can Down syndrome test be wrong NIPT?

NIPT is quite accurate for Down syndrome (99%) and for trisomy 18 (97%). It is less accurate for trisomy 13 (87%). In all cases, the results should not be considered certain unless confirmed by diagnostic testing. Two diagnostic procedures can usually confirm or disprove the results of NIPT.

Is it worth getting NIPT test?

Why have an NIPT? The NIPT is highly sensitive and picks up more than 99% of cases of Down syndrome. But it is still a screening test rather than a diagnostic test.
