Immunoglobulin G
Understanding Immunoglobulin G
What is Immunoglobulin G?
The Immunoglobulin G is a blood test that measures the level of Immunoglobulin G (IgG) antibodies in the body. It helps diagnose and monitor infections, immune system disorders, or autoimmune diseases.
IgG are the most common type of antibodies in the blood that helps fight off infections primarily caused by microorganisms (e.g., bacteria, viruses, allergens etc.) and provides long-term immunity after exposure to an infection or vaccination. An Immunoglobulin G test can help detect illness, infection or chronic inflammation.
The Immunoglobulin G test, often done as part of an immunology panel, helps to assess immune health, monitor infections and guide treatment decisions for immunocompromised conditions. Abnormal IgG levels can indicate immunodeficiencies, chronic or recurrent infections, or autoimmune diseases, where the immune system mistakenly attacks the body.
No special preparation is required for this test. Inform your doctor about all the medications or supplements that you are taking as these may affect the test results, potentially requiring adjustments or temporary discontinuation before the test. Additionally, narrate your complete medical history, especially history of allergy or vaccinations to your doctor to help them relate your clinical and laboratory findings.
Lab test results may vary across laboratories. Interpretation of the test results requires expert interpretation. Therefore, do not self-medicate and always consult a doctor to understand the implications of your test findings. The insights from an Immunoglobulin G test help doctors formulate your overall treatment plan.
What is Immunoglobulin G used for?
The Immunoglobulin G test is done:
- To diagnose past/previous infections by measuring the body’s immune response.
- To evaluate the effectiveness of vaccinations.
- In individuals with frequent infections to assess immune function.
- To monitor the health of individuals with autoimmune diseases.
- To identify individuals at risk of immunodeficiency.
- To assess the immune status before surgery or other medical procedures.
What does Immunoglobulin G measure?
The Immunoglobulin G test measures the concentration of IgG antibodies present in the serum. These antibodies are produced by the immune system in response to specific pathogens or infections. Elevated levels of IgG can indicate recent or chronic infections, while lower levels may suggest an impaired immune response or deficiency. This test is crucial for assessing an individual’s immune status and provides valuable information for doctors to make informed clinical decisions regarding diagnosis, treatment strategies, and ongoing management of various health conditions.
