Answer to Question 1

ANS: C
An elevated immature reticulocyte fraction is associated with a bone marrow response to anemia. It is a reliable indicator of changes in erythropoietic activity and may prove to be a valuable monitoring tool for patients with anemia, such as those with chronic renal failure who are treated with recombinant erythropoietin.

Answer to Question 2

ANS: D
Limitations and interferences may be related to either the methodology or inherent problems in the blood sample. In its literature the manufacturer defines instrument limitations. Some of the method limitations are, in fact, the result of inherent specimen problems.
