Abstract

A method for isolating nucleated fetal erythrocytes (NFEs) from a maternal blood sample by separating erythrocytes in the maternal blood sample from all other nucleated cells therein using a leukocyte depletion device; and isolating NFEs from nonnucleated maternal erythrocytes. Preferably the maternal blood is peripheral maternal blood. The isolated NFEs can then be analyzed for genetic disorders and the like, such as by in situ hybridization.
