PrenatalSafe® is a non-invasive prenatal test that detects chromosomal abnormalities by analyzing cell-free fetal DNA from a pregnant woman’s blood sample. The PrenatalSafe® Karyo test detects aneuploidies and structural chromosomal abnormalities in the fetus on each chromosome, with results very similar to the determination of the fetal karyotype performed with invasive prenatal diagnosis procedures, as well as including the determination of fetal sex (optional).
The test highlights: common fetal aneuploidies in pregnancy, such as those relating to chromosome 21 (Down syndrome), chromosome 18 (Edwards syndrome), chromosome 13 (Patau syndrome) and the sex chromosomes X and Y (such as for example Turner Syndrome or Monosomy of the X chromosome), less common aneuploidies (such as for example the trisomy of chromosomes 9, 16, 22) and deletions or segmental duplications, detectable on all chromosomes.
PrenatalSafe® Karyo is suitable for both single and twin pregnancies *.
PrenatalSafe® Karyo can be integrated, for free, with RhSafe® test, a non-invasive prenatal exam that, analyzing the fetal DNA isolated from a blood sample of the mother to be, allows to determine fetal Rh(D) Factor. RhSafe® test is optional, and is performed for free (on request) in Rh(D) negative pregnant women, with a Rh(D) positive male partner.
* In the case of a dichorionic twin pregnancy, it will not be possible to investigate aneuploidy of the sex chromosomes.
