Answer to Question 1

ANS: B
Target cells are not seen in hereditary spherocytosis. They are present in all the other conditions listed.

Answer to Question 2

The best test to differentiate sickle cell trait from anemia is hemoglobin electrophoresis. Sickle cell trait should have roughly 40 Hb S and 55 Hb A, whereas sickle cell anemia should have predominantly Hb S with a variably increased Hb F and no Hb A.
