Components: Vital signs assessment Inspection, palpation, percussion, and auscultation Targeted examinations based on presenting symptoms Step 3: Formulating Differential Diagnoses Based on history and physical exam, generate a list of possible conditions ranked by likelihood. Use clinical prediction rules and evidence-based guidelines to prioritize. Step 4: Ordering Diagnostic Tests Select appropriate investigations to confirm or exclude diagnoses. Considerations: Test sensitivity and specificity Pre-test probability Risks and costs associated with testing Guidelines and evidence for test use Step 5: Interpreting Results and Refining Diagnosis Analyze test outcomes in conjunction with clinical data to arrive at a definitive diagnosis.
