The problem
Laboratory catalogs use different names, codes, specimen fields, and update formats. Comparing tests requires checking both the record and its source.

Search and compare laboratory tests across source catalogs, with downloadable records and clear source status.
My role
Laboratory data modeling, search and comparison design, and application engineering.
What I built
- Searchable test catalog with source links and missing-data labels
- Side-by-side test comparison
- Versioned public dataset downloads
The result
A public application that lets users find tests, compare source records, and download published data.

Implementation
How it works
Source records pass through schema validation and terminology search. Results retain their source status, can be compared side by side, and are included in downloadable releases only when approved for publication.
Technical context and methods
The public application includes published records, staged submissions, and live source candidates with distinct labels. Tests cover search, record relationships, downloads, and the rules for displaying federated results.
