Differentiating Types and Causes AIHA is not a single condition but a classification that encompasses several subtypes with different underlying mechanisms. This test detects antibodies or complement proteins attached to the surface of red blood cells.
AIHA Diagnosis Symptoms Causes Overview
This may involve imaging studies like a chest X-ray or a CT scan to examine the lymph nodes, spleen, and liver. A direct Coombs test is performed on a blood sample and is considered positive if it causes the red blood cells to clump together, or agglutinate.
A precise diagnosis is critical to distinguish AIHA from other forms of anemia and to initiate appropriate treatment promptly. These symptoms arise directly from the reduced oxygen-carrying capacity of the blood.
AIHA Diagnosis Symptoms Causes Overview
These tests differentiate AIHA from other causes of hemolysis, such as mechanical damage or infections. A critical next step is the reticulocyte count, which measures the bone marrow's response; in AIHA, this count is usually elevated as the body attempts to compensate for the loss of red blood cells.
