Answer to Question 1

Answer: Spherocytes in peripheral circulation cause bilirubinemia that subsequently causes bilirubin buildup. Excessive bilirubin production leads to the formation of gallstones.

Answer to Question 2

Answer: Ham and sucrose lysis tests: PNH: increased lysis; HS, HE, HPP, and OHS: normal lysis
Osmotic fragility: HS, HPP, and OHS: increased osmotic fragility; HE, and PNH: normal osmotic fragility
Immunophenotyping: PNH: CD55 and CD59: low intensity staining; HS, HE, HPP, and OHS: normal immunophenotyping
Intracellular ion concentration: OHS: increased intracellular sodium; HS, HE, HPP, and PNH: normal intracellular ion concentration
