To explore the diagnostic value of dual-fluorescence staining for BV, we first executed a dual-fluorescence staining method to analyze the vaginal secretions of 265 patients, then confirmed our diagnoses by consulting clinical physicians and by using Nugent scoring of Gram staining.Results: There were 16,905 patients who were diagnosed with vaginitis over the previous 2 years, with a median age of 32 (minimum age of 9 years and maximum of 84 years). Of these patients, we noted 10,887 cases (64.40%) of BV. Our staining results revealed that the dual-fluorescence method was consistent with Gram staining in the diagnosis of BV, with a P value of less than .001 using a χ 2 test and a consistency kappa value of 0.896. Compared with Gram staining, the dual-fluorescence staining method required an acceptable time (2.2 min vs 2.5 min, respectively) and exhibited different visual effects (green and yellow vs purple and red, respectively).Conclusion: Dual-fluorescence staining for the detection of bacterial diseases of the vagina exhibited acceptable consistency with Gram staining and performed well with respect to dyeing time, stability, and the interpretation of results.
