Abstract
The present invention provides assay systems and methods for determining the percent fetal contribution of cell-free DNA in a maternal sample from a pregnant female with an egg donor pregnancy. Further provided, are assay systems and methods for determining a statistical likelihood of the presence or absence of a fetal aneuploidy in a maternal sample using a determined percent fetal cell-free DNA in the sample.
