  29. What are some methods used tertiary prevention? (3)
    • risk factor modification (weight loss)
    • reducing harmful exposure
    • rehabilitation
  30. What is screening? (2)
    • detects potential disease indicators
    • indicates suspicion
  31. What is diagnostic testing?
    • detects the presence of a disease
    • results in definitive diagnosis
  32. Does early detection mean better outcome?
    not always!
  33. Define True positive.
    The patient has the disease and the test is positive
  34. Ideally, primary prevention will reduce the ______ and _______ of disease
    incidence and prevalence

    the patient does not have the disease and the is negative
  39. Define False negative.
    the patient has the disease but the test is negative
  40. What is sensitivity?
    probability that a test correctly classifies people with the disease as having the disease
  41. What is specificity?
    the probability that a test correctly classifies people without the disease as not having the disease.
  42. What is positive predicted value?
    the probability that someone who tests positive actually has the disease.
  43. What is negative predicted value?
    the probability that someone who tests negative actually does not have the disease
