What is the cause of hemoglobinuria?
Hemoglobinuria is a condition in which the oxygen transport protein hemoglobin is found in abnormally high concentrations in the urine. The condition is caused by excessive intravascular hemolysis, in which large numbers of red blood cells (RBCs) are destroyed, thereby releasing free hemoglobin into the plasma.
What is the most common cause of hemoglobinuria?
Kidney tumor. Malaria. Paroxysmal nocturnal hemoglobinuria , disease in which red blood cells break down earlier than normal. Paroxysmal cold hemoglobinuria , disease in which the body’s immune system produces antibodies that destroy red blood cells.
