The next-generation sequencing method was used to qualitatively detect specific gene variants and ploidy changes of 39 autosomal arms (including overall increase in chromosome arms, homozygous deletions and heterozygous deletions) in cervical exfoliated cell samples at the molecular level.

As an auxiliary diagnosis of cervical cancer, the cervical lesions are fine and clear, so as to provide reference for clinicians, judge more accurately and pertinently whether further invasive diagnosis and intervention treatment measures are needed, avoid over treatment, and find cervical cancer in cases of Cin2 and below.
