Diagnostics
Tests that find disease earlier and guide treatment: molecular diagnostics, liquid biopsy, AI-assisted pathology and at-home testing.
What are medical diagnostics? Medical diagnostics are tests and tools used to detect, identify or monitor disease — from blood and tissue tests to imaging and at-home sample kits. Newer approaches analyze DNA shed by tumors, use AI to read samples, or move testing into the home.
