ELANEE Vaginal pH Self-Test - For detecting vaginal infections Itching, burning or an uncomfortable feeling in the intimate area may indicate a disturbance of the acid-base balance in the vagina, which can promote a bacterial infection. Vaginal infections can often trigger premature births, which is why the pH self-test can help to detect them early and thus reduce the risk of premature birth. The self-test allows the pH value of the vaginal environment to be easily determined from home, and the result can be read directly using a color scale on the individual packages.
