IgG Subclass 2 (IgG2) Serum Test by Nephelometry

IgG2 Test Overview

The IgG2 test measures the levels of IgG2 antibodies in the blood. This type of immunoglobulin test helps understand how well your immune system can fight bacterial and some viral infections. IgG is a major antibody in the bloodstream, split into four subclasses: IgG1, IgG2, IgG3, and IgG4, where IgG2 is vital for combating infections.

This test is crucial for diagnosing and monitoring various health conditions, including repeated infections, autoimmune diseases, and immune deficiencies. By checking IgG2 levels, doctors can assess your immune system's effectiveness against certain pathogens and pinpoint any underlying health issues

The IgG Subclass 2 (IgG2) is an important component of the immune system that helps protect against bacterial infections. The IgG2 test is primarily used in the evaluation of patients with clinical signs and symptoms of humoral immunodeficiency or combined immunodeficiency.

The IgG2 test is typically performed along with other IgG subclass tests (IgG1, IgG3, IgG4) to assess the overall immune status. Evaluation of IgG subclass levels helps to identify specific subclass deficiencies and guide appropriate treatment and management strategies.
