Test of fetal DNA

During pregnancy, some DNA fragments of the fetus and the placenta circulate in the mother’s blood. GenoSearch Mamma® is a non-invasive prenatal test, totally risk free, which allows the analysis of free circulating fetal DNA, isolated from a sample of maternal blood, and evaluates the aneuploidies of chromosomes 21, 18, 13 and sexual chromosomes ( X and Y), as well as the possibility to carry out the determination of fetal sex (optional). The amount of fetal DNA suitable to perform the test can be found from the tenth week of pregnancy onwards. The test is performed by drawing a maternal blood sample from which the present fetal DNA is isolated, in order to determine the presence of any chromosomal abnormalities. GenoSearch Mamma® is extremely reliable, has a reliability over 99% in detecting Trisomies 21, 18 and 13, and 95% for detecting monosomy X with false positive percentages below 0.1%. This test also provides for the possibility, where expressly required, to perform a second level in-depth study, which allows to identify the presence in the fetus of aneuploidies and the chromosomal structural alterations of each chromosome.
