Immunocomplexes (PEG)

The Immunocomplexes (PEG) analysis is a specific type of immunological blood test used to detect the presence of certain complexes in the blood. These complexes form when antibodies in the blood bind to antigens, which can indicate various immune responses in the body. IntroLab Laboratory Belgrade is available for this analysis, as well as other blood tests.

Why is the Immunocomplexes (PEG) analysis performed?

This analysis is often used when there is suspicion of autoimmune diseases, such as systemic lupus erythematosus (SLE) and rheumatoid arthritis, or suspicion of other immune disorders. The presence of immunocomplexes can indicate an active immune response in the body to certain antigens.

What are the indications for the analysis?

• Symptoms of autoimmune disease
• Chronic inflammatory diseases
• Suspected allergic reactions
• Monitoring therapy for certain immune disorders

What symptoms might require testing?

Symptoms can vary depending on the specific disease or condition, but often include:

• Fatigue
• Joint pain
• Rash
• Swelling
• Difficulty breathing

How to prepare for the Immunocomplexes (PEG) analysis?

The analysis requires a blood sample. It is recommended that the sample be taken in the morning, preferably on an empty stomach, although it is best to consult with laboratory staff regarding specific instructions.

What happens after the analysis?

The results are usually available within a day. Depending on the results, the doctor may recommend additional tests to determine the course of therapy.

Interpreting the results

Elevated levels of immunocomplexes may indicate an active immune response, while low levels may indicate the absence of a response or effective removal of complexes from the blood.

Disease prevention

Prevention depends on the specific disease or medical condition. On the other hand, regular check-ups and Immunocomplexes (PEG) analyses, a healthy diet, avoiding known allergens, and proper therapy can often help prevent the manifestation of symptoms.

Association with other tests

When there is suspicion of autoimmune diseases or other immune disorders, the Immunocomplexes (PEG) analysis is often not done in isolation. Here are some other tests that are often combined with it:

• ANA (Antinuclear Antibodies): This analysis is often used to detect autoimmune diseases such as systemic lupus erythematosus (SLE).
• Anti-dsDNA: Specific for diagnosing and monitoring SLE.
• RF (Rheumatoid Factor): Used for diagnosing rheumatoid arthritis.
• Anti-CCP: Also used for diagnosing rheumatoid arthritis and can indicate a more severe form of the disease.
• C3 Complement and C4 Complement: Levels of these proteins may be reduced in people with active SLE or other autoimmune diseases.

Taking blood samples for various analyses allows doctors to gain a more detailed insight into the patient’s immune status and more precisely diagnose and monitor diseases. It is always advisable to consult with a doctor about which tests are most appropriate in addition to Immunocomplexes (PEG) in your case.
