Sterility test by ISO 11737-2: Aerobic bacteria, anaerobic bacteria and fungi
Sterility testing measures the growth of microorganisms on a product after the product has been sterilized. A sterile device or product is free from viable microorganisms. The purpose of sterilization is to inactivate microbiological contaminants to transform devices from non-sterilized to sterilized. Sterility can be assessed when defining, validating, or maintaining a sterilization process. Testing includes method validation by determining the initial bacterial count of control suspensions and testing the suitability of the culture mediums for aerobic and anaerobic bacteria and fungi. Also, the suitability of the test for the specific product is assessed. Sterility testing is used to analyze the growth of aerobic bacteria, anaerobic bacteria, and fungi (yeasts and molds) on the product. For this reason, 3 replicate sample specimens are needed. The results are given as negative (no growth observed) or positive (growth observed) and the price includes one result per micro-organism per product.
