3. Subclinical diagnosis of autoimmune hemolysis
In addition to the clinical examination, autoimmune hemolytic disease also needs the following laboratory tests to confirm the diagnosis:
Peripheral blood tests: Decreased red blood cell count, normal or enlarged red blood cells , the more severe the anemia, the larger the red blood cell size tends to be. Hematocrit decreased by less than 10% in severe cases. Often there are increased reticulocytes and erythrocytes on the peripheral blood smear Blood chemistry: Bilirubin is increased, mainly indirect bilirubin, LDH is increased, haptoglobin is decreased. Vigorous, reticulocytes increased, granulocyte count and platelet count were normal. Positive direct Coombs test The indirect Coombs test can be positive indicating a large number of saturated autoantibodies sites of erythrocyte binding and thus appear in serum.
