What is Immunoglobulin G (IgG4) 4 Subclass?

The Immunoglobulin G (IgG4) subclass test measures the level of IgG4 antibodies, which are the least abundant IgG subclass. IgG4 is often associated with chronic inflammatory conditions and immune tolerance rather than acute immune responses.

Why is this test important?

This test is crucial for diagnosing and monitoring IgG4-related disease (IgG4-RD), a systemic fibroinflammatory condition. It can also be relevant in evaluating certain autoimmune disorders or allergic responses.

How to Prepare

No special preparation required.
