Clinical Nexus screening and clinician-led conditional testing occupy the upper lane; validation and certification are separate from open foundation-model work below. No anatomical people, fabricated chart, autonomous diagnosis or MedGemma-to-Nexus claim remains.

Summary: Google Research describes integrating MedSigLIP and MedGemma into Nexus, a certified tuberculosis-screening tool used across roughly 40 facilities by more than 90 clinicians. The publisher reports processing over 25,000 chest X-rays, usually in under 45 seconds, while emphasizing independent validation, local offline deployment and clinician responsibility for final decisions.

Why it matters: You will learn how model selection, independent validation, local processing and human review fit together in a constrained clinical workflow. The case helps evaluators separate operational deployment evidence from unsupported claims that a model alone diagnoses patients or improves outcomes.
