Why do four buttons display for CLASS when users order the iron assay procedure?

The presence of four buttons for the CLASS when users order the iron assay procedure is due to the procedure hierarchy finding four associated buttons in the iron assay record. This structure allows for more granular selection and enhances the user interface by making additional options available, based on how the procedure is defined within the system. Each button may correspond to a different aspect of the test, allowing users to select specific types of iron assays or to customize test orders according to their needs or clinical guidelines.

This hierarchy of procedures is designed to streamline the ordering process and improve efficiency, as it facilitates the selection of relevant options without having to navigate through unrelated procedures. The inclusion of multiple buttons is a reflection of the flexibility built into Epic's system to accommodate various clinical scenarios and usage patterns.
