Description

一种细胞检测方法A cell detection method 技术领域Technical field
本发明涉及细胞检测领域,尤其涉及一种细胞检测方法。The invention relates to the field of cell detection, in particular to a cell detection method.
背景技术Background technique
目前的细胞检测方法一般是通过检测样本的DNA倍体来判断细胞是否异常,由于受其他不确定因素影响较多,导致判断结果不够准确。目前也有通过单一检查L1表达来判断细胞是否异常的判断方法,当检测出L1表达为阴性时无法判断细胞为异常还是正常,从而难以判断L1表达为阴性时的意义,在L1表达状态为阴性时,判断结果也不准确。Current cell detection methods generally determine whether the cell is abnormal by detecting the DNA ploidy of the sample. Due to the influence of other uncertain factors, the judgment result is not accurate enough. At present, there is also a method for judging whether a cell is abnormal by single-checking L1 expression. When L1 expression is detected as negative, it is impossible to determine whether the cell is abnormal or normal, so it is difficult to determine the significance of L1 expression when negative. , The judgment result is also inaccurate.
