  • METHOD AND DEVICE FOR CLASSIFICATION OF URINE SEDIMENT GENOMIC DNA, AND USE OF URINE SEDIMENT GENOMIC DNA
    Publication number: 20230126920
    Abstract: The present invention relates to a DNA classification method, comprising calculating the MHL value of a DNA methylation haplotype block and/or the DNA copy number variation data of a sample of interest; calculating the similarity between the MHL value of the DNA methylation haplotype block of the sample of interest DNA and the MHL value of a DNA methylation haplotype region of a respective classification label, and/or the similarity between the copy number variation data of the sample of interest DNA and the DNA copy number variation data of a respective classification label; and determining a classification for the DNA in the sample of interest by using a classifier model and based on the similarity. The present invention provides new means with good specificity and sensitivity for detection of tumors in the urogenital system.
