Application of high-fluorescence cells in rapid identification of benign and malignant serosal cavity liquid

The invention discloses an application of high-fluorescence cells in rapid identification of serosal cavity liquid benign and malignant. The application comprises the following steps: taking serosal cavity liquid samples of a plurality of patients; performing exfoliative cytology examination on the first sample to obtain a benign or malignant tumor cytology qualitative result; high-fluorescence cells of the second sample are detected through a flow fluorescence staining method, and a detection result is obtained; taking the tumor cytology qualitative result of the first sample of all patients as a gold standard, and drawing an ROC curve according to the detection result of the second sample; finding out a critical value of the high-fluorescence cells corresponding to the area under the maximum curve as a cutoff value for identifying benign and malignant serous cavity liquid; calculating the correlation between the exfoliative cytology examination and the high-fluorescence cell detection; if the correlation me
