Abstract: The present invention discloses a method for detecting the mutation and methylation of tumor-specific genes in ctDNA, and this method can simultaneously detect the mutation (including point mutation, insertion-deletion mutation, HBV integration and other mutation forms) and/or methylation of tumor-specific genes in ctDNA in one sample.
