True or false? A patient's blood urea nitrogen (BUN) was 50 mg/dL on Day 1, and the control serum for BUN was within 2 SD of the mean on that day.
 
  On Day 2, the same patient's BUN was 70 mg/dL; again, the control value was acceptable. Should the physician interpret this increase in the BUN as a real pathologic change in the patient? (The only control level available for this test has a mean value of 20 mg/dL and a standard deviation of 2 mg/dL.)
  A) True
  B) False
