What are the key differences between iso 17025 and clia for genomic labs

Updated 9/11/2025

ISO 17025 and CLIA are both standards used in laboratory environments, but they serve different purposes and have distinct requirements. ISO 17025 is an international standard that applies to all types of laboratories, focusing on quality management and the technical requirements necessary for producing valid results. It emphasizes continual improvement and customer satisfaction. CLIA (Clinical Laboratory Improvement Amendments), on the other hand, is specific to the United States and applies to clinical laboratories. Its primary focus is ensuring the accuracy, reliability, and timeliness of patient test results, with strict regulatory compliance requirements. While ISO 17025 is more flexible and globally recognized, CLIA is mandatory for clinical labs in the US and focuses more on patient safety and test accuracy. Labs may choose ISO 17025 for its broader scope and international recognition, while CLIA is necessary for compliance in clinical settings in the US.
