The Science Behind IgG and IgG4 Testing

Understanding the role of IgG and IgG4 antibodies in food allergies is crucial to grasp the significance of the 96 General Food Panel: IgG/IgG4 by US BioTek and the ImmunoCAP test.

Food allergies can be a complex and challenging condition to manage. While most people are familiar with immediate allergic reactions, such as hives or difficulty breathing, delayed allergic reactions can also occur. These delayed reactions can be more subtle and manifest as digestive issues, skin problems, or even mood disturbances. Identifying the specific food allergens responsible for these delayed reactions can be a daunting task.

The Role of IgG and IgG4 in Food Allergies

IgG and IgG4 antibodies are part of the immune system's response to foreign substances, such as food allergens. Unlike the more well-known IgE antibodies, which are involved in immediate allergic reactions, IgG and IgG4 antibodies are associated with delayed hypersensitivity reactions. These reactions can occur several hours or even days after consuming the offending food.

When a person is exposed to a food allergen, their immune system produces IgG and IgG4 antibodies specific to that allergen. These antibodies attach themselves to the allergen, forming immune complexes. These immune complexes can then circulate throughout the body, triggering an inflammatory response in various tissues and organs.

It's important to note that IgG and IgG4 antibodies are not always indicative of an allergic response. They can also be present in individuals who tolerate certain foods without any adverse reactions. However, elevated levels of these antibodies in response to specific foods can suggest a potential sensitivity or intolerance.

How IgG/IgG4 Tests Work

The 96 General Food Panel: IgG/IgG4 by US BioTek and the ImmunoCAP test work on the principle of measuring antibody levels in response to specific food allergens. These tests aim to identify IgG and IgG4 antibodies that have formed immune complexes with food allergens.

First, a blood sample is taken from the individual being tested. The sample is then processed in a laboratory, where it undergoes a series of tests to measure the levels of IgG and IgG4 antibodies specific to a wide range of food allergens. The results are usually reported as a numerical value, indicating the concentration of antibodies present for each allergen tested.

It's important to understand that IgG and IgG4 testing is not a definitive diagnostic tool for food allergies. These tests provide valuable information about a person's immune response to specific foods, but they should be interpreted in conjunction with a thorough clinical evaluation and other diagnostic tests, if necessary.

By analyzing the blood sample, these tests can provide insights into an individual's immune response and potential food sensitivities. This information can be used to guide dietary modifications and elimination protocols, helping individuals manage their food allergies effectively.
