Abstract
An apparatus for determining exposure to an oxidative sterilant is described. The apparatus includes a chemical indicator for indicating exposure to the oxidative sterilant and a biological indicator for determining the effectiveness of the exposure to the oxidative sterilant. The chemical indicator has a metallic surface with a non-pH sensitive permanent indicator on the surface for indicating exposure to the oxidative sterilant. The chemical indicator may be on a self-contained biological indicator. The biological indicator and chemical indicator may be inside a test pack, where the test pack restricts sterilant flow to the indicators.
