The so-called tumor cell DNA quantitative analysis, also called tumor cell DNA quantitative analysis, through the cell DNA quantitative analysis system, the DNA multiplicity in the cell nucleus quantitative detection, you can determine the physiological state of the cell and pathological state, the content of the genetic material changes in the cell morphology of the change in the cell earlier. Through the quantitative analysis of the period to early detection of precancerous lesions and tumor occurrence, the application of cellular deoxyribonucleic acid quantitative analysis system for the detection of cancer, as well as precancerous lesions, to achieve automatic detection, can overcome the shortcomings of manual observation of the subjective, poor repeatability, improve the detection rate and sensitivity of the lesion detection, and through the evaluation of the degree of change of the cells and a variety of parameters, you can judge the prognosis of the tumor, to guide the Tumor treatment.
