Definition And Diagnosis

Evans Syndrome: A Comprehensive Overview

Definition and Diagnosis

Evans syndrome, an autoimmune disease, attacks and destroys certain types of blood cells. The diagnosis requires the simultaneous or subsequent presence of both autoimmune hemolytic anemia and autoimmune thrombocytopenia.

Autoimmune Hemolytic Anemia

This condition occurs when the immune system mistakenly identifies red blood cells as foreign and destroys them, leading to anemia.

Autoimmune Thrombocytopenia

In this disorder, the immune system attacks platelets, resulting in a decreased ability for blood to clot, potentially causing excessive bleeding.

Blood tests play a crucial role in confirming the diagnosis. These tests measure hemoglobin levels for anemia, platelet counts for thrombocytopenia, and assess the presence of autoantibodies targeting red blood cells and platelets.
