Immunoglobulin G

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.
