Homozygous C disease is a blood disorder that results in mild hemolytic anemia. The disease often does not present obvious symptoms and is typically not diagnosed until adulthood.
There are many conditions that affect red blood cells and hemoglobin C disease is one of them. To diagnose the condition a doctor will do a blood test to check the hemoglobin count and to do an overall evaluation of the health of the blood. The condition is primarily found in people of African descent.
