About the Message Evaluation and Testing Service
As jurisdictions implement HL7 message mapping guides (MMGs), they should use the Message Evaluation and Testing Service (METS). METS will help them to evaluate the test messages they develop against required messaging, vocabulary, and programmatic standards before they are sent to the Message Validation, Processing, and Provisioning System (MVPS). METS ensures that CDC receives high-quality messages for processing and provisioning to CDC programs.
