Fetal Cell Prenatal Tests
Our fetal cell prenatal tests use the fetal cells found in the mother's blood to test for its paternity.
How They Work
Our fetal cell prenatal paternity tests use both fetal cells and fetal DNA isolation from maternal blood. During pregnancy, a variety of cell types of fetal origin, as well as fetal DNA, cross the placenta and circulate within maternal peripheral blood. This fetal material is a source of information about the genetic makeup of the developing fetus. Fetal genetic material can be detected in maternal blood early in gestation.
The rarity of fetal nucleated cells in maternal blood has made their isolation particularly challenging. To obtain quantities sufficient for analysis, the use of enrichment techniques is required. The investigators begin with a 30 ml maternal venous blood sample.
An initial enrichment step facilitates removal of many maternal non-nucleated cells through density gradient centrifugation. Subsequent
