Bioburden Testing
Bioburden Testing is a quality control process used to measure the number of bacteria and other microorganisms present on medical devices, pharmaceuticals, or raw materials. Think of it like a cleanliness inspection that ensures products are safe for use in healthcare settings. This testing is important in industries that make medical devices, drugs, or cosmetics because it helps prevent contaminated products from reaching patients or consumers. Companies need this testing to meet safety regulations and quality standards, similar to how restaurants need health inspections.
