Sign in with MicrosoftAI-Assisted Features
This application uses AI-powered auto-correction technology to assist with HL7 v2 message validation. Rule-based algorithms and pattern matching identify and suggest corrections for common validation errors.
How Auto-Correction Works
- Detection: Gazelle EVS validation errors are analyzed.
- Analysis: Rules identify correctable HL7 v2.4 issues.
- Correction: Suggested fixes are applied to message content.
- Validation: Messages are re-validated until complete or no more corrections are possible.
Human Oversight and Control
You maintain full control: corrections are performed at your request. Review reports, download corrected files, and verify every change before submission.
Important: Auto-correction may not resolve every issue. Always review corrected files and validation reports before submitting to production systems. This tool assists, but does not replace, human HL7 expertise.
