The role of pH-metry in the diagnosis of vaginal infections

The purpose of the study. Study the clinical significance of pH-metry for diagnosis of bacterial vaginosis (BV) and evaluate the optimal values of the normal micro ecology of the vagina. In addition, the objectives of the study included a comparative study of different methods and indicators of pH-metry. Materials and methods. 214 women aged 18 to 45 years (mean age 30,2±7,7 years) were examined, of which were formed two representative groups. The first group consisted of 114 patients with BV, the second - 100 healthy women selected in the comparison group. Each test was performed on six females pH measuring the different test methods or systems, only two groups - 1284 pH measurements. Comparison was made between foreign and domestic pH test strips on a new modification Colpe test pH.Results and discussion. In BV patients, the pH of the vagina on the measurement ionometers average equaled 6,49±0,07 and 6,24±0,034 depending on modelipriborov. In healthy women, vaginal pH content was within the average was 4,21±0,022 and 4,31±0,041 (p<0,001). Strips of Colpe pH test increments 0,2-0,3-0,5 division were the most effective, because oniobladayut high sensitivity (90%) and specificity (85%) in the measurement of pH in patients with BV. Received findings indicate a high diagnostic value of pH-metry BV algorithm diagnosis of vaginal infections.Conclusion. pH-try vaginal fluid stepper division 0,2-0,3-0,5 is important and must express method to immediately get objective information about the acid-base status of the vagina. Russian plastic strips Colpe test pH can be used to assess the acidity of vaginal fluid to meet all the necessary conditions for the qualitative diagnosis (sensitivity - 90%, the specificity - 85% BV) and must further be used in gynecological practice.
