Understanding the 144 Food Panel: IgA/IgG4 by US BioTek
The 144 Food Panel is a comprehensive food allergy test offered by US BioTek that measures IgA and IgG4 antibodies in response to a wide range of food antigens. This innovative test aims to identify potential food sensitivities that may contribute to various health conditions such as digestive disorders, skin problems, and chronic inflammation. By analyzing the specific antibody levels, this test can help individuals identify foods that might trigger adverse reactions in their bodies.
IgA, one of the immunoglobulins primarily found in mucosal secretions, plays a vital role in protecting the body against pathogens encountered in the digestive and respiratory systems. It acts as a frontline defense mechanism, preventing harmful substances from entering the body through these vulnerable entry points. IgG4, on the other hand, is an antibody subclass associated with delayed hypersensitivity reactions. This means that while IgA acts immediately upon exposure to a potential allergen, IgG4 is involved in a more delayed immune response. Both IgA and IgG4 play crucial roles in immune responses against food antigens.
What is the 144 Food Panel?
The 144 Food Panel is a comprehensive test offered by US BioTek that screens for IgA and IgG4 antibodies against 144 common food allergens. This extensive panel covers a wide range of food groups, including grains, dairy, meats, legumes, fruits, vegetables, spices, and more. By testing for specific antibodies, this panel helps identify potential triggers for adverse food reactions, providing individuals with valuable information to make informed dietary choices.
The Role of IgA/IgG4 in Food Allergy Testing
When it comes to food allergy testing, IgA and IgG4 antibodies play crucial roles in immune responses against food allergens. IgA, as mentioned earlier, is responsible for defending the mucosal surfaces of the body. It acts as a shield, preventing harmful substances from entering the bloodstream through the digestive and respiratory systems. IgG4, on the other hand, is associated with delayed hypersensitivity reactions. This means that IgG4 antibodies are involved in immune responses that occur hours or even days after exposure to a potential allergen.
Measuring the levels of IgA and IgG4 antibodies can provide valuable insights into food sensitivities and potential allergic reactions. By analyzing these antibody levels, healthcare professionals can determine if a person has heightened immune responses to specific food antigens, indicating a potential food sensitivity or allergy.

The Patch Test: An Alternative Approach
In addition to the 144 Food Panel, the Patch Test is another method used to identify food allergies. Unlike the blood-based approach of the 144 Food Panel, the Patch Test involves applying small amounts of food extracts directly onto the skin to evaluate the body's reaction. This test aims to identify immediate hypersensitivity reactions, which can manifest as skin rashes, itching, or swelling.
The Basics of the Patch Test
During a Patch Test, small patches containing food extracts are applied to the skin, typically on the back. The patches are left on for a specific period, usually 24 to 72 hours, allowing for potential reactions to occur. After the designated time, the patches are removed, and the skin is examined for any signs of a reaction. The presence of redness, inflammation, or other skin abnormalities indicates a positive reaction to the tested food extract.
The Patch Test is a non-invasive procedure that can be performed in a clinical setting. It is often used when there is a suspicion of food allergies and when the symptoms experienced by an individual cannot be explained by other medical conditions. This test provides valuable information about immediate hypersensitivity reactions, which can help guide dietary choices and avoid potential allergic reactions.
During the Patch Test, the healthcare professional carefully selects the food extracts to be tested based on the individual's reported symptoms and suspected allergens. Common food allergens such as peanuts, eggs, milk, wheat, and soy are often included in the test panel. However, additional food extracts can also be included based on the individual's specific dietary habits and potential exposure to certain allergens.
Comparing the Effectiveness of Patch Test with 144 Food Panel
Both the Patch Test and the 144 Food Panel have their advantages and limitations. While the Patch Test allows for the evaluation of immediate hypersensitivity reactions, it may not detect delayed reactions. Additionally, the observed skin reactions may not always directly correlate with digestive or systemic symptoms.
On the other hand, the 144 Food Panel provides a comprehensive analysis of IgA and IgG4 antibody levels and covers a wide range of potential food allergens. It can help identify delayed reactions and provide a more holistic understanding of an individual's food sensitivities. This blood-based test measures the immune response to specific food proteins and can detect sensitivities that may not manifest as immediate skin reactions.
It is important to note that the Patch Test and the 144 Food Panel are not mutually exclusive. In some cases, healthcare professionals may recommend both tests to gather a more complete picture of an individual's food allergies and sensitivities. The combination of these tests can provide valuable information for developing personalized dietary plans and managing food-related symptoms.
When considering which test to undergo, it is crucial to consult with a healthcare professional who specializes in allergies and immunology. They can evaluate the individual's medical history, symptoms, and specific needs to determine the most appropriate testing approach.
