Template
When a diagnostic test result is interpreted, verify the reasoning accounts for how common the condition is, not just the test's accuracy. For a rare condition, even an accurate test yields many false positives, so a positive result may still mean the condition is unlikely. Confirm the interpretation reflects predictive value given prevalence rather than equating a positive test with having the disease, and flag any output that reads a result as confirmation while ignoring the base rate.
