Why Use HL7 Tools?
Frequently Asked Questions
Which HL7 versions do these tools support?
The HL7 tools support HL7 v2.x messages across common versions used in hospitals and integration engines, including segment, field, component, and repetition parsing.
Can I troubleshoot interface issues without uploading messages?
Yes. All parsing happens locally in your browser, so ADT, ORM, ORU, SIU, and other HL7 payloads stay on your device.
Are these tools suitable for production message validation?
They are useful for analysis, debugging, and education, but they should complement, not replace, your formal interface testing and production monitoring processes.
Do these tools support FHIR?
No. This category is currently focused on HL7 v2.x message workflows rather than FHIR resources or APIs.
Can I use them with hospital integration engines?
Yes. They are designed for quick inspection of messages exported from interface engines, EHR integrations, lab systems, RIS, and ADT feeds.
