Autoimmune hemolytic anemia by warm antibodies is characterized by the presence of antibodies capable of acting against red blood cells. The most frequently observed type of antibody is IgG, which interacts better with red blood cells at a temperature of 37°C. This is the case of a 54 year-old female palient who for five months had been experiencing generalized weakness, exertional dyspnea, and generalized jaundice . Laboratory studies included: haemoglobin 3,5 g/dL: direct bilirubin 0,88 mgldL; indirect bilirubin 2,6 mgldL; total serum bilirubin 3,5 mgldL; lactate dehydrogenase 1016 UlL; positive direct Coombs test positive IgG antibodies. With these findings in mind, autoimmune hemolytic anemia by warm antibodies was díagnosed.
