19. Suppose that for a clinician, the "test" threshold for a particular, serious health condition is 20%, and the "treat" threshold is 80%. A patient walks into the clinician's office and - from talking to them - the clinician estimates them as having a probability of a particular condition of 15%. What should the clinician's next action be? (Pick the single best answer) a. Treat the patient for the condition b. Conduct further diagnostic testing ?? ** c. Neither test nor treat the patient d. Conduct further diagnostic testing, but only if it's not invasive testing (e.g., no biopsies). ?? 20. Regardless of what you answered to the previous question, suppose you test the patient further, and after the test your confidence that the patient has the condition is 70%. What is your next action? (Pick the single best answer) a. Treat the patient for the condition b. Conduct further diagnostic testing c. Neither test nor treat the patient d. Conduct further diagnostic testing, but only if it's not invasive testing (e.g., no biopsies). **
