This examination counts the quantity of immunoglobulins, or antibodies, in your blood. Proteins called antibodies are produced by the immune system to combat pathogens like bacteria and viruses. To combat various forms of these chemicals, your body produces different types of immunoglobulins.
Three distinct types of immunoglobulins are typically measured by an immunoglobulin test. They go by the names of IgG, IgM, and IgA. IgG, IgM, or IgA levels that are abnormally low or high could indicate a dangerous medical condition.
What does it serve?
A blood test for immunoglobulins can help in the diagnosis of a number of illnesses, including:
- viral or bacterial infections
- Immunodeficiency, a condition that weakens the body’s defenses against illnesses and infections
- an autoimmune disease, like lupus or rheumatoid arthritis. Your immune system mistakenly attacks healthy cells, tissues, and/or organs as a result of an autoimmune illness.
- certain cancers, including multiple myeloma
- neonatal infections
Why do I require a blood test for immunoglobulins?
If your doctor suspects that your immunoglobulin levels are either too high or too low, you could need this test.
Too low levels can cause the following symptoms:
- recurring or uncommon viral or bacterial illnesses
- persistent diarrhea
- nasal infections
- infected lungs
- familial immunodeficiency history
A chronic illness, an infection, a form of malignancy, or an autoimmune disease may all be indicated by excessive immunoglobulin levels. These illnesses have a wide range of symptoms. To determine whether you are at risk for one of these diseases, your doctor may use data from your physical examination, medical history, and/or additional testing.
What is the average level of immunoglobulin?
Adult Normal Ranges: IgA 0.8 – 3.0 g/L, IgM 0.4 – 2.5 g/L, and IgG 6.0 – 16.0 g/L.
What signs or symptoms point to a lack of IgG?
- Respiratory infections and sinus infections.
- Infected gastrointestinal tract.
- Infected ears.
- illnesses that cause sore throats.
- Rarely, infections that are serious and potentially fatal.
