A QUANTITATIVE ASSAY FOR TARGET DNA IN A MIXED SAMPLE COMPRISING TARGET AND NON-TARGET DNA

摘要

The present disclosure relates generally to an assay to detect and quantitate target nucleic acid in a mixture of target and non-target nucleic acid, kits useful for same and its use in non-invasive diagnostic methodologies. The assay comprises identifying copy number variation (CNV) polymorphisms present in the target nucleic acid and absent in non-target nucleic acid. Embodiments disclosed include quantitating the level of fetal DNA in sample of maternal DNA and fetal DNA, and quantitating the level of donor-derived DNA in sample from a transplant recipient comprising self DNA and non-self or donor DNA.
