Abstract

The method of measuring pH of vaginal moisture, which includes providing a pH indication, color comparison measurement, and swabbing structure on a carrier stick; manipulating the stick between its opposite ends, to obtain pH indication of vaginal moisture at one end of the stick; visually interpreting that indication to also obtain pH measurement of such moisture near that one end of the stick; again manipulating the stick between its opposite ends, including endwise reversing it, to swab the vaginal cavity in the area from which pH indication was obtained; and disposing of the stick, whereby disposition of the pH indication, measurement and swabbing structure is thereby obtained in one disposal step; including providing pH indication means in the form of a strip on the one end of the stick; and providing a smooth surface protective tip facing endwise at one end of the stick.
