Welcome to the DEX
Diagnostics Exchange

The DEX Diagnostics Exchange is an online test registry and workflow solution that laboratories and diagnostics manufacturers use to submit information about their specific molecular diagnostics (MDx) tests, and providers and payers use to understand and evaluate new and existing tests. The DEX Diagnostics Exchange assigns a unique Z-Code Identifier to each diagnostics test and adds it to the test registry catalog for reference and review by other stakeholders in the healthcare system.
