NIPT is a screening test that give information about the chance of having a baby with trisomy 21 (Down syndrome), trisomy 18 and trisomy 13.
This test has to be performed from 12 weeks of pregnancy. This test is a screening test, not a diagnostic one. In case of ultrasound abnormalities, a puncture of amniotic fluid has to be performed. In case of abnormal NIPT result, it would be confirmed by an amniocentesis.
