Egg Yolk Immunoglobulin G (IgG) Antibody Level (Serum/Plasma)
This test measures the presence of antibodies your immune system produces in response to exposure to egg yolk proteins. It helps assess whether you may have an allergy or sensitivity to eggs.
["This test helps identify potential egg allergies by detecting immune system reactions to egg proteins."]

What This Test Measures
The test detects specific antibodies (IgG) your body creates when exposed to egg yolk proteins. These antibodies are part of your immune response and can indicate past or current sensitivity. The test is typically performed on serum or plasma from a blood sample.
Why It’s Ordered
Your healthcare provider may recommend this test if you have symptoms like hives, digestive issues, or respiratory problems after eating eggs, or if you’re planning to eat eggs while pregnant or with a compromised immune system. It’s also used to monitor immune responses in certain medical conditions.
How It’s Done
A small blood sample is drawn from your arm. The blood is processed to separate serum or plasma, which is then tested for egg yolk-specific antibodies using an immunoassay method. This process is quick and usually done in a lab.
What to Expect Before or After
No special preparation is needed, but inform your provider about any medications or supplements you take. After the test, you may experience mild bruising or soreness at the injection site. Results are typically ready within a few days.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Positive results indicate your immune system has recognized egg yolk proteins, which may suggest an allergy or hypersensitivity. High levels of these antibodies can trigger allergic reactions, including skin rashes, digestive discomfort, or breathing difficulties. This test helps guide dietary adjustments or allergy management plans.
