Non-invasive prenatal testing (NIPT) has the potential to screen for a wider range of genetic conditions than is currently possible at an early stage of pregnancy and with minimal risks. As such, there have been calls to apply a ‘threshold of seriousnes
Non-invasive prenatal testing (NIPT) uses fetal genetic material obtained from a maternal blood sample to detect certain genetic conditions during pregnancy. Current literature often refers also to NIPT as non-invasive prenatal diagnosis (NIPD). This terminology may be misleading given that, at the ...

Non-invasive prenatal testing (NIPT) can be used to accurately detect fetal chromosomal anomalies early in pregnancy by assessing cell-free fetal DNA present in maternal blood. The rapid diffusion of NIPT, as well as the ease and simplicity of the test r
