IgG subclasses (IgG 1, 2, 3, 4)

The IgG subclass analysis is an important test performed at the IntroLab laboratory in Vrachar. This immunological blood test aims to determine the concentration of IgG 1, 2, 3, and 4, which are specific types of immunoglobulin G (IgG) in the blood.

Why is IgG subclass analysis important?

As mentioned, this analysis provides information about the concentration of individual IgG subclasses in the blood. It is of great importance to understand the body’s immune response and identify potential immune system disorders. This analysis can help diagnose immune disorders, assess the risk of infections, and monitor therapy for certain conditions.

What are the indications for this analysis?

Measuring IgG subclass levels may be indicated in the following situations:

• Suspected immune disorders: For patients with symptoms and signs suggesting an immune system disorder, evaluating IgG subclass concentrations can help in making a diagnosis.
• In cases of recurrent infections: If a patient frequently suffers, the analysis may reveal reduced concentrations of certain IgG subclasses vital for an effective immune response.
• Monitoring therapy: For patients already undergoing treatment for certain immune disorders, this test can be used to monitor the effectiveness of therapy and assess the response to treatment.

Who performs the IgG subclass analysis?

Laboratory technicians perform the analysis. Our laboratory has skilled personnel and the most modern equipment, ensuring the accurate and reliable execution of this analysis. Our experienced medical professionals will carefully analyze your blood sample and interpret the results.

How are the results of the IgG subclass analysis interpreted?

The results of the IgG subclass analysis are interpreted according to the reference values determined for each IgG subclass. However, a low concentration of a specific IgG subclass may indicate possible immune deficiencies or a predisposition to infections. On the other hand, a high concentration of certain IgG subclasses may be associated with certain immune disorders.
