# CapturedTestImageResponse

Model ID: `CapturedTestImageResponse`

SAFE CDX presigned retrieval URL for an already-captured test-kit image.

Returned by GET /patients/{patient_id}/diagnostics/{test_id}/image. The
``image_url`` is a short-lived presigned AWS S3 GET URL — it is never a
permanent/public link, consistent with the PHI-image-handling pattern used
for other Health Cloud diagnostic imagery.

Type: `object`
