Laboratory Tests to Confirm an Autoimmune Cause of Anemia
Anemia is a common condition where a person has a lower than normal number of red blood cells. It can be caused by a variety of conditions, including autoimmune disorders. For those who may have an autoimmune cause of anemia, laboratory tests can help confirm the diagnosis.
Complete Blood Count (CBC): A CBC is a common test that measures the different components of a person's blood, including red blood cells. It can help to determine the type and severity of anemia.
ESR (Erythrocyte Sedimentation Rate): The ESR is a test that measures the amount of inflammation in the body. An increased ESR may indicate an autoimmune cause of anemia, as many autoimmune disorders cause inflammation.
Ferritin: Ferritin is a molecule found in the blood that stores iron. Low levels of ferritin may be a sign of an autoimmune cause of anemia, as many autoimmune disorders interfere with the body's ability to absorb iron.
Direct Coombs Test: The direct Coombs test detects antibodies that are attacking red blood cells. If the antibodies are present, it may indicate that an autoimmune disorder is causing anemia.
Antinuclear Antibody Test (ANA): The ANA test looks for antibodies that are targeting the body's own cells. A positive ANA test may indicate an autoimmune cause of anemia.
By running these laboratory tests, doctors can get a better understanding of the cause of anemia and determine the best course of treatment.
