A patient presents with anemia, jaundice, and an increased reticulocyte count. What is the most likely diagnosis based on these clinical findings?

The combination of anemia, jaundice (indicating increased bilirubin levels due to hemolysis), and an increased reticulocyte count (indicating a bone marrow response to anemia by producing more red blood cells) points towards a hemolytic anemia. Autoimmune hemolytic anemia is a condition where the immune system produces antibodies against the patient's own red blood cells, marking them for destruction.
