What labs are consistent with a hemolytic process?
What type of anemia involves the attachment of IgM and complement to red cells?
Cold autoimmune hemolytic anemia
The red cells in sickle cell disease are more susceptible to hemolysis because:
They possess an abnormal hemoglobin which polymerizes upon deoxygenation
