IgG4 (Immunoglobulin G4)
Measures IgG4 levels, often used to diagnose IgG4-related disease, an autoimmune condition.
Overview of IgG4 (Immunoglobulin G4) in Aluva
The IgG4 Serum test measures the level of IgG4 antibodies in the blood. IgG4 is a subclass of immunoglobulin G (IgG), which is a type of antibody produced by the immune system. IgG4 antibodies play a role in immune response, particularly in controlling allergic reactions and modulating inflammation. They are involved in maintaining immune tolerance and preventing excessive immune responses. Elevated levels of IgG4 can be associated with certain conditions, including autoimmune diseases and chronic inflammatory disorders. It is often used to help diagnose or monitor conditions like IgG4-related disease, which can cause inflammation in multiple organs. This test is useful in differentiating IgG4-related conditions from other types of immune system disorders.
Why consider IgG4, Serum test?
- It helps identify conditions associated with elevated IgG4 levels, such as IgG4-related disease, which can cause inflammation and damage to multiple organs.
- Elevated IgG4 can be a marker of chronic inflammation or immune response, assisting in diagnosing diseases where this subclass is involved.
- Evaluating Allergic Reactions
- For individuals already diagnosed with IgG4-related disease or similar conditions, the test helps monitor disease progression and response to treatment.
Who should get IgG4, Serum test done?
- Individuals with Suspected IgG4-Related Disease showing unexplained inflammation or swelling in organs like the pancreas, salivary glands, or lymph nodes.
- Individuals experiencing chronic or atypical allergic reactions where IgG4 involvement is suspected.
- Patients with a diagnosed IgG4-related condition who need to monitor disease progression or response to treatment.
More Information about IgG4, Serum test
IgG4 antibodies play a role in immune response, particularly in controlling allergic reactions and modulating inflammation. They are involved in maintaining immune tolerance and preventing excessive immune responses. IgG4 is produced by plasma cells in response to chronic antigen exposure, such as from persistent infections or certain autoimmune conditions.
