Process for determining viability of test microorganisms of biological indicator and sterilization detection device for determining same

A sterilization detection device, comprising:

• a single container comprising a main body and a lid, the main body having an interior volume including a first compartment, a second compartment, and a third compartment,
• wherein the first compartment contains a biological indicator comprising test microorganisms on a spore test strip;
• wherein the biological indicator has been subjected to a sterilization process,
• wherein the second compartment contains a viability detection medium comprising hydrogen peroxide and arranged to be brought into contact with the biological indicator in the first compartment to cause production of a gaseous reaction product when one or more of the test microorganisms of the biological indicator are viable;
• and
• wherein the third compartment contains a sensing device configured to detect a presence or absence of the gaseous reaction product produced by the biological indicator combined with the viability detection medium, the sensing device comprising one or more than one electrical connector coupled to an electronic device, wherein the presence of the gaseous reaction product indicates a presence of viable test microorganisms and the absence of the gaseous reaction product indicates an absence of the viable test microorganisms, wherein the sensing device comprises a capacitive sensor.
