Abstract

Abstract Background To investigate the positive rate and clinical applicability of liquid—based fungal method for detecting of vaginal fungi. We collect the secretions from the posterior vaginal fornix and the vaginal wall of 198 patients with clinically suspected fungi vaginitis patients for study. Methods The vaginal fungi of vaginal discharge were detected by fluorescence method, i.e., by liquid—based thin-layer fungi fluorescence morphology staining detection kit (liquid—based fungal method), saline smear method and fungal culture method. Results The positive rate of liquid-based fungal method, saline smear method was 50%, 25.75% respectively. The positive rate of liquid-based fungal method were 50%. The true positive rate of liquid-based fungal method (87.85%) was higher than that of saline smear method (45.79%, P < 0.001), which was easy to miss diagnosis. Moreover, the Kappa (K) of liquid-based fungal method was 0.81, and P < 0.01, which was statistically significant, indicating that the consistency of the two detection methods is good. Of the eight common symptoms of fungal vaginitis, the positive symptom coincidence rate of liquid-based fungal method was consistent with that of fungal culture method. It was also easier to see fungi under a microscope than with saline smear method. Conclusion The liquid-based fungal method has a high positive coincidence rate and accuracy in the detection of vaginal fungi, and it is convenient to operate and implement steps. Therefore, it may be applied in clinical practice. Or a combination of several detection methods can be used.
