Purpose of the test

The primary purpose of the IgG test is to determine the presence and amount of IgG antibodies in the blood, helping diagnose conditions related to the immune system, such as immunodeficiencies or autoimmune disorders.

Who Should Get Tested

Individuals who show symptoms of an immune system disorder, recurrent infections, or those suspected of having an autoimmune condition might be recommended to undergo an IgG test.

High doses of biotin supplements can affect test results, causing false elevation or reduction. It's recommended to avoid taking biotin for at least 72 hours before blood collection. If you are taking biotin, inform the personnel collecting the blood so that they can provide specific instructions.
Interpreting Test Results

Normal IgG levels vary depending on age and individual factors. Abnormally high or low IgG levels can indicate an immune system disorder, infection, or other medical conditions. It's essential to discuss the results with a healthcare professional for a comprehensive understanding and potential next steps.
