Description
Why It’s Done:
The IgG Serum Test is ordered for several reasons, such as:
• Diagnosing immune system disorders, including primary immunodeficiency.
• Evaluating chronic infections (e.g., hepatitis, HIV, or other viral/bacterial infections).
• Assessing autoimmune conditions (e.g., lupus, rheumatoid arthritis).
• Monitoring treatment effectiveness in certain diseases.
• Evaluating allergy-related immune responses.
• Checking vaccine response or past exposure to infections.
Preparation:
• No special preparation is usually required.
• The test involves a simple blood draw, typically from a vein in your arm.
• Inform your doctor if you’re taking any medications, especially immunosuppressants or steroids, as these can affect results.
• Fasting is not needed unless other tests are being done at the same time.
