DNA Method for Screening Cancer By Analyzing Index of Tumor-Derived DNA

摘要

The present invention relates to a method of providing information, a composition and a kit for analyzing a tumor or a lesion thereof. Specifically, the present invention relates to a method of providing information, a composition and a kit for analyzing a tumor or a lesion thereof by quantitatively analyzing the concentrations of tumor or lesion-derived DNA fragments and normal cell-derived DNA fragments, and then determining the reference value using the concentration ratio as an index, through oligonucleotides capable of amplifying normal cell-derived DNA fragments and oligonucleotides capable of amplifying DNA fragments derived from a tumor or lesion thereof in DNA isolated from biological samples.
