Allergy review
This page plays the provider's data-collection app. It asks your health app for your allergy list — one tap, like autofill — or you can type them in yourself. Either way you land in the same review, and because shared records usually carry the allergen and little else, it asks only for what's missing.
Your allergy list — from your app
What the clinic stores
The same review, two ways — the check-in page is ordinary application code, so this choice belongs to the EHR, not the protocol.
