Abstract:
Objective To preliminarily evaluate the performance and species specificity of Candida spp.latex immunochromatography kit for detecting Candida spp.in vaginal secretion.Methods The vaginal secretions in 354 cases of suspected vaginitis and 9 genus of 22 species of common vaginal infecting organisms were by adopting the smear/Gram staining and Candida spp.kit.The results were compared with those detected by smear/Gram staining semi-quantitative method.The detection performance and species specificity of Candida spp.kit for detecting clinical specimens were evaluated.Results Compared with the smear/Gram staining method,the sensitivity,specificity,accuracy,positive predictive value and negative predictive value of Candida sp.kit were 93.81%,99.10%,97.31%,98.14% and 96.90%,respectively;compared the smear/Gram staining semiquantitative method,the Candida spp.kit for detecting Candida spp.in vaginal secretion still had higher specificity and acceptable sensitivity when the Candida spp.concentration was lower in specimens;in the speciese specificity evaluation,6 kinds of Candida spp.were positive and other 16 kinds of common vaginal infecting organisms all were negative.Conclusion The Candida spp.kit for detecting Candida spp.in vaginal secretion has higher clinical and species specificity,sensivity,positive prediction value and negative prediction value.
