Why do I need an immunoglobulins blood test?
You may need this test if your health care provider thinks your immunoglobulin levels might be too low or too high.
Symptoms of levels that are too low include:
Frequent and/or unusual bacterial or viral infections
Chronic diarrhea
Sinus infections
Lung infections
Family history of immunodeficiency
If your immunoglobulin levels are too high, it may be a sign of an autoimmune disease, a chronic illness, an infection, or a type of cancer. Symptoms of these conditions vary greatly. Your health care provider may use information from your physical exam, medical history, and/or other tests to see if you are at risk for one of these diseases.
