a patient makes antibodies that recognize antigens on red blood cells and leads to the destruction of these cells. which would you expect?

If a patient creates antibodies that recognize antigens on RBCs and then destroy them, the patient is suffering from autoimmune hemolytic anemia.

Autoimmune hemolytic anemia(AIHA) is a kind of rare immune disorder, where the body produces antibodies that recognize the antigens on red blood cells and cause their premature destruction i.e., hemolysis. This disease can be idiopathic or result from an underlying disease.

Typically, red blood cells have a lifespan of 120 days. The severity of this disease is determined by the life span of the red blood cells and how rapidly destroyed cells are getting replaced by new cells in the bone marrow.

Symptoms of AIHA include unusual fatigue, tachycardia, breathing problems, and jaundice.
