The difference between the conventional NIPT test, also referred to as cell-free NIPT (cfNIPT), and EVITA TEST COMPLETE is that cfNIPT analyses fragments of fetal DNA circulating in maternal blood. These fetal DNA fragments are contaminated with maternal DNA, hence limiting the resolution of analysis. EVITA TEST COMPLETE uses a technology to isolate fetal cells from maternal blood and analyse pure fetal DNA. Hence, EVITA TEST COMPLETE has the ability to detect smaller changes in the fetal DNA.
