Special dyeing reagent for epithelial tissue diseased cells and preparation process of special dyeing reagent

The invention discloses a special dyeing reagent for epithelial tissue diseased cells and a preparation process of the special dyeing reagent. The special dyeing reagent for the epithelial tissue diseased cells is prepared from the following raw materials in percentage by weight: folic acid, methylene blue, acetic acid, fructose, galactose, glucose and purified water. The preparation process specifically comprises the following steps: taking materials; dissolving the fructose, the galactose and the glucose into the purified water, and dissolving until the fructose, the galactose and the glucose are dissolved; sequentially adding the methylene blue, the folic acid and the acetic acid in a stirring process, and uniformly stirring to obtain a finished product. After detection and dyeing, a result is compared with a comparison color card and the lesion degree of epithelial cells can be accurately known; the special dyeing reagent is simple to operate, sanitary and convenient to use and long in storage period, and
