About the Message Evaluation and Testing Service

The CDC Message Evaluation and Testing Service (METS) is a message validation service for public health jurisdictions to use to validate nationally notifiable disease (NND) HL7 case notification messages before they are sent to the Message Validation, Processing, and Provisioning System (MVPS) for processing and provisioning to CDC programs. Because METS allows jurisdictions to validate HL7 messages against the required messaging, vocabulary, and programmatic standards, METS ensures that high-quality messages are being sent to MVPS.

METS is publically available and may be accessed at https://mets.cdc.gov.

For additional information on METS, please reference the METS User Guide.
