The following RBC indices are obtained on a patient when calculated using results from manual methods:
 
  MCV: 73 fL

  a. The hematocrit is too low.
  b. The hemoglobin is too low.
  c. The red count is too high.
  d. It is impossible to come to any conclusion.

Question 2

Answer to Question 1

ANS: C
The MCHC is in the reference range and the red cells are normochromic. These then correlate with one another; therefore the hemoglobin and hematocrit appear valid. The cells are also normocytic, which means that the MCV and MCH should also both be in the reference range, but they are not. Because the red count is the denominator for both of these determinations, it must be too high and thus falsely decrease both the MCV and MCH.

Answer to Question 2

ANS: B
The ESR tube must be kept at the absolute perpendicular to obtain a valid ESR result. Even only a slight tilt of the pipette (tube) causes the ESR to increase.

Chronic necrotizing aspergillosis has a slowly progressive process that, unlike invasive aspergillosis, does not spread to other organ systems or the blood vessels. It most often affects middle-aged and elderly individuals, spreading to surrounding tissue in the lungs. The disease often does not respond to conventionally successful treatments, and requires individualized therapies in order to keep it from becoming life-threatening.
