Unifying laboratory test codes across several systems
After a merger or across a network of sites, each laboratory system (LIS) uses its own codes and names for the same test. Without a common catalogue, results cannot be integrated or the data analysed.
- Starting data
- Each system’s catalogue: local code, name, specimen, method, units and reference ranges.
- What the AI suggests
- Groups equivalent tests across systems, proposes a master catalogue with its LOINC code and flags conflicts: different units (mg/dL versus mmol/L), or specimens and methods that do not match.
- What the user decides
- Confirms or splits each group, resolves conflicts and sets the unit conversions.
- Outcome
- A versioned master catalogue and equivalence table, ready for integration, the electronic health record and data analysis.
