摘要: The invention provides methods of increasing the fetal fraction in maternal blood and plasma. This increase in fetal fraction improves the accuracy and decreases the “no call” rate for prenatal testing that measures fetal DNA in maternal blood.

摘要: Disclosed herein are methods for determining the copy number of a chromosome in a fetus in the context of non-invasive prenatal diagnosis. In an embodiment, the measured genetic data from a sample of genetic material that contains both fetal DNA and maternal DNA is analyzed, along with the genetic data from the biological parents of the fetus, and the copy number of the chromosome of interest is determined. In an embodiment, the maternal serum is measured using a single-nucleotide polymorphism (SNP) microarray, along with parental genomic data, and the determination of the chromosome copy number is used to make clinical decisions pertaining to the fetus.
