Method Validation
Method Validation is a quality control process used in laboratories to confirm that a testing procedure works correctly and gives reliable results. It's like double-checking that a recipe will consistently produce the same dish every time. Labs must prove their testing methods are accurate before they can use them for real samples. This process is especially important in industries like pharmaceuticals, food safety, and environmental testing. You might also see it called "analytical method validation," "test method validation," or "procedure qualification."
