The present invention relates to a new, non-invasive method for detecting chromosomal aneuploidy by analyzing a sample from a pregnant woman. The detection is based on the ratio between the amount of a fetal methylation marker located on a chromosome relevant to the aneuploidy and the amount of a fetal genetic marker located on a reference chromosome, offering improved accuracy.
