Let us assume that a new screening test was prepared to detect ovarian cancer. The chart below shows the frequency of its results. Which of the following is true if we take as a referential value the result of 0-30 µg/dL?

  3. C. some healthy women will have a false-positive result.
  4. D. all women with cancer will have a positive result.
