RhSafe® is a NON-INVASIVE prenatal test that, by analyzing fetal DNA isolated from a blood sample of the pregnant woman, allows to determine the fetal Rh Factor. The test identifies pregnancies at risk for the hemolytic disease of the fetus and the newborn, and therefore reduces the use of anti-D immunoglobulins in cases where the fetus is Rh(D) negative as the mother. RhSafe® is included, for free, in all PrenatalSafe® levels when the pregnant woman is Rh(D) negative and her partner is positive (certified by Rh status report). Suitable for twin pregnancies.
