External Quality Assessment (EQA) is a system used by medical laboratories to ensure their test results are accurate and reliable. Think of it like a report card for laboratories. Outside organizations send unknown samples to labs for testing, then compare their results with other labs to make sure everyone is getting the same answers. This process is sometimes called "Proficiency Testing" or "Laboratory Quality Control." It's a crucial part of maintaining high standards in medical testing and is often required for laboratory accreditation.
