What is the HL7 Message Generator?

The HL7 Message Generator creates realistic HL7v2 test messages for any message type. Select a message type (ADT^A01, ORM^O01, ORU^R01, etc.), customize patient demographics and clinical data, and generate valid HL7 messages ready for integration testing.

All generated data is synthetic — no PHI involved. This makes it safe to share test messages with trading partners, load into integration engines, or use in development and QA environments.

Supported Message Types

• ADT (A01, A02, A03, A04, A08, A28, A31) — Patient administration
• ORM (O01) — General orders
• ORU (R01) — Observation results / lab reports
• SIU (S12, S14, S15) — Scheduling
• MDM (T02) — Medical document management
• RDE (O11) — Pharmacy orders

Why Generate Test Messages?

Integration testing with real HL7 data is risky (PHI exposure) and limited (not enough edge cases). Generated messages give you full control: create boundary conditions, missing fields, unusual character encoding, long field values, and other scenarios that are hard to find in production data.

Validate Against Your Spec

Generate a test message, then validate it against your Conformance Spec to verify your rules catch the right issues. A powerful workflow for building and testing interface specifications.
