The occult blood in the urine is due to the presence of hemoglobin in the urine. Normal plasma contains a small amount of free hemoglobin bound to haptoglobin. Because of its large molecular weight, it cannot be filtered from normal glomerular filtration membrane, so hemoglobin does not appear in normal human urine. Clinically, it is most common in nephritis, and in general, blood transfusion reaction, faba bean disease, paroxysmal hemoglobinuria, malaria, extensive burns, and inflammation caused by certain drugs or poisons may be positive. Hemoglobinuria may occur at the onset of various hemolytic anemias. In addition, patients with paroxysmal nocturnal hemoglobinuria and allergic hemoglobinuria may be positive.
