Growth promotion testing

Growth promotion testing is a quality control process used in laboratories to ensure that growth media (substances used to culture microorganisms) can support bacterial or fungal growth. Before using a new batch of media, a small sample is tested by adding known microbes to verify they grow as expected. If the microbes grow properly, the media is considered effective and ready for routine testing. This process helps confirm that the media will reliably support microbial growth, ensuring accurate and consistent laboratory results for quality assurance and safety.
