|Title:||METHOD AND APPARATUS FOR ANALYZING DEGREE OF CROSS-CONTAMINATION OF SAMPLE|
Provided are a method and an apparatus for analyzing a degree of cross-contamination of a sample with regard to a target sample, comprising the steps of: acquiring first sequence information of a nucleic acid fragment from each of a target sample and an additional sample, and second sequence information of a nucleic acid fragment from a mixed sample of the target sample and the additional sample; calculating allele frequency from each of the first sequence information and the second sequence information acquired; and comparing the calculated allele frequencies with regard to a specific chromosomal locus. By measuring a degree of cross-contamination between samples at a specific chromosomal locus, the method and the apparatus can guarantee reliability to variation detection results.
