Antibody test - Immunoglobulin G (IgG)
S-IgG is a blood test that measures the levels of Immunoglobulin G (IgG), the most abundant antibody in the blood. This test is essential for detecting and monitoring infections and immune-related conditions that may affect your health.
Why should you test your IgG antibodies?
Immunoglobulin G (IgG) is a key component in the body's defense against infections. By measuring the IgG levels in the blood, you can get valuable information about the activity of the immune system and identify both current and previous infections. Consider this test if you experience the following symptoms or suspicions:
- Unexplained infections: If chronic infections, such as herpes or Epstein-Barr virus, are suspected, an IgG test can help establish the diagnosis.
- Recurring infections: If you often get infections or have difficulty treating them, an IgG test can reveal potential immunodeficiency conditions.
- Autoimmune diseases: If autoimmune diseases are suspected, where the immune system attacks the body's own tissues, the IgG levels can provide important information.
- Treatment follow-up: If you are being treated for an infection or an immune-related condition, an IgG test may be used to monitor the treatment effect.
Elevated IgG levels may indicate:
- Autoimmune and inflammatory diseases, where the immune system attacks healthy tissue
- Chronic bacterial or viral infections
- Oncological diseases such as leukemia and lymphoma
- Allergic reactions
Low IgG values can be related to:
- Immunological diseases, such as HIV/AIDS
- Primary immunodeficiency diseases, for example hypogammaglobulinaemia
- Liver diseases or spleen dysfunction
When is an IgG test recommended?
- For individuals who wish a comprehensive assessment of their immune system.
- For people with symptoms of infection or inflammation who need a clearer diagnosis.
- For those monitoring existing health conditions or treating specific immune-related diseases.
- For health conscious individuals who want regular updates on their health status.
