Diagnosis, testing and prediction

This branch covers identifying conditions and anticipating health risks, divided by the diagnostic question or method: diagnostic labels, laboratory and tissue examination, imaging, ancestry testing and predictive health. It leaves disease-specific diagnosis, statistical assessment of test and prediction performance, trial outcome measurement, companion diagnostic regulation and clinical-term coding to neighbouring branches.

• What a diagnosis claims — diagnosis as a process and label, kinds of label, diagnostic errors, boundaries and questions for writers
• Pathology and laboratory medicine — professional roles, divisions and settings, specimen handling, laboratory quality, communication and molecular methods
• Surgical pathology and the tissue diagnosis — tissue examination, preparation and interpretation, specimen differences, intraoperative consultation and the pathology team
• Imaging techniques and what they show — techniques in cancer care, three-dimensional reconstruction and dental treatment planning
• What an ancestry DNA test can and cannot tell — marker comparisons, variation in estimates, information beyond ancestry and data privacy
• Predictive health — proposed benefits, data and predictive rules, repeated and behavioural measurements and limits of genetic prediction
