Fetal Cell-free Plasma DNA Concentrations in Maternal Blood Are Stable 24 Hours after Collection: Analysis of First- and Third-Trimester Samples

1 Jan 2003

Abstract excerpt

The discovery of intact fetal cells in maternal blood has led to the possibility of noninvasive prenatal genetic testing. Although extensive work has been performed on maternal blood in the hope of developing a reliable method for the recovery of intact fetal cells, the total number of recoverable cells is quite small, averaging 19 nucleated fetal cells in 16 mL of blood (1)(2). This is contrasted by a relatively...
