ABSTRACT
Diagnosis of vaginal discharge is frequently performed in an empirical way, leading to inadequate treatment. This study tested the accuracy of a self-collection kit for microbiological study of the vaginal content. One hundred and forty-two women of Family Health Program units in Niterói and Piraí cities were enrolled in order to have their vaginal content studied. A brief explanation and a self-collection kit were provided in order to sample the vaginal content. The self-collection kit was composed of one empty plastic tube, two glass slides, a long handle cytobrush, an identification card and guideline notes. The vaginal sample was applied on the glass slides by the women and stained by Gram technique. A second sampling was done by the medical personnel. The microbiological diagnosis in a blinded analysis was made under optical microscopy. A validation diagnosis test was done taking the medical collection results as a gold standard. A total of 106 women had followed the protocol and were included in the study. Microbiological analysis was unsatisfactory in 12 cases (6 cases of self-collection material and 6 cases of medical collection). The microbiological analyses in the self-collection and in the medical collection material were respectively: bacterial vaginosis in 21.7 percent and 17.9 percent, non bacillar flora in 10.3 percent and 11.3 percent, vaginal trichomoniasis in 5.66 percent and 5.6 percent, candidiasis in 3.78 percent and 2.8 percent and a normal microbiota in 52.8 percent and 56.6 percent. The Kappa coefficient suggested a "very good correlation" of the microbiological results between the two methods of collection (K=0.7945). The self-collection kit provides samples for microbiological analysis of the vaginal microbiota as good as medical collection.
