Shorr’s solution is primarily used for hormonal cytodiagnostics of gynecology samples. During menstrual cycle hormones cause changes in vaginal epithelium, and staining smears of cytology samples using Shorr’s solution enables differentiation between eosinophilic (acidophilic) and cyanophilic (basophilic) cells. Ratio between the cells provide the information about the influence of follicle of stimulating hormone (FSH) and luteinizing hormone (LH): amount of eosinophilic cells is greater under the influence of follicle stimulating hormone (FSH), and amount of cyanophilic cells is greater under the influence of luteinizing hormone (LH). The solution is ready to use, and the staining procedure itself is rapid and simple. It is also used for better visualization of sperm morphology.
