Answer to Question 1

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

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.

It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
