Abstract
An absorbent pad, for use in absorbing secretions from a person's body, includes a pH indicator material indicating by a colour change the acidity or alkalinity of a liquid coming into contact with it. The pH indicator material is wetted by the secretions absorbed by the pad, and thereby provides an indication of the health condition of the person's body.
