ABSTRACT

introduction. Normal vaginal pH is considered in a rank of 4.0-5.0, in sexual active women and those with normal menstrual cycles. Some authors consider that measurement of vaginal pH and the test of Whiff could be useful to exclude abnormal vaginal discharge.
objective. To evaluate vaginal pH value and cérvico-vaginal infections, as well as possible relation between pH value with etiologic agent.
material and method. The study was based on patients who attended the DOC (Opportune Detection of Cancer) program at the Laboratorio de Biología Celular de la Facultad de Medicina de la Benemérita Universidad Autónoma de Puebla. A measurement of vaginal pH and cérvico-vaginal exfoliative cytology was made to all the patients between autumn 2008 and autumn 2010.
results. A total of 341 women were attended, 6 were excluded due to bleeding. In Group A (negative to vaginal cervico infection) 130 women were included, and 205 in Goup B (with vaginal cervico infection). In Group A 46 (35.38%) patients had a pH of 5. In group B, 74 (36.10%) had a pH of 5. With regard to the microorganisms that were found, the value of more frequent pH in each was: Trichomonas vaginalis pH 4, 100% of cases; Gardnerella vaginalis pH 7, 40%; Fungi pH 4, 44,4%; cocci pH 5, 44,64%; lactobacilli pH 4.70, 59%. The normal vaginal pH is in a rank from 4 to 5. In patients with infection by Gardnerella vaginalis it is › 5, whereas the rank before the cocci presence varies of 5-6. The infection by fungi appears with a pH of 4-5.
conclusion. Coinfections can apparently generate a pH in normal ranks, group of symptoms of cervico-vaginal infection with an excess of lactobacilli and a pH of 4 exists. The measurement of pH must be accompanied by a careful study of the group of symptoms in order for it to be considered a diagnostic tool.
