We presented a case of false negative NIPT results, which may occur through biological mechanisms rather than poor quality, technical errors or negligence. She said the NIPTs all use very similar technology, and a negative result one one would almost certainly result in a negative result on the other. False-positive results can occur in the presence of placental mosaicism, vanishing twin syndrome, or an unidentified maternal condition, such as mosaicism or

}); $('#mce-'+resp.result+'-response').html(msg); The use of NIPT outside of these designated settings has not been validated and therefore is not recommended because the accuracy of the results is unknown at this time. I recently had my 20 wk ultrasound and the results were mostly great except for one little notation which stated that in one of the images the nuchal fold looked somewhat prominent but that they do not see it on other images from that area.

However, foetal cfDNA in maternal plasma originates from apoptotic placenta cytotrophoblasts [6]. A negative NIPT equates to roughly a 1 in 70,000 chance. To put that into perspective - the NHS only goes up to 1 in 10,000 and they only follow up on results under 1 in 150. Its a very slim chance. https://doi.org/10.1186/s12920-020-00751-8, DOI: https://doi.org/10.1186/s12920-020-00751-8.
