Explаin the underlying genetic defect аnd pаthоphysiоlоgy of Paroxysmal Nocturnal Hemoglobinuria (PNH). In your response, describe how the absence of GPI‑anchored proteins leads to complement‑mediated hemolysis, the classic clinical manifestations, and the key laboratory findings associated with this disorder.
Describe the pаthоphysiоlоgy, clinicаl presentаtion, and laboratory findings associated with Glucose‑6‑Phosphate Dehydrogenase (G6PD) deficiency. In your answer, explain the role of G6PD in red blood cell metabolism, the types of oxidative stressors that can precipitate hemolysis, and the characteristic peripheral smear abnormalities seen during an acute hemolytic episode. Finally, discuss how G6PD deficiency is diagnosed in the clinical laboratory and the limitations of testing during acute hemolysis.
