144 Food Panel: IgG/IgG4 by US BioTek Vs ELISA Test
Food intolerance and allergies are common health concerns that can significantly impact a person's quality of life. Many individuals experience adverse reactions to certain foods, ranging from mild discomfort to severe allergic reactions. Understanding the causes and identifying specific food triggers are essential steps in managing these conditions effectively.
Understanding Food Intolerance and Allergies
Food intolerance refers to difficulty digesting certain foods, leading to unpleasant symptoms such as bloating, gas, or diarrhea. It can be a result of various factors, including enzyme deficiencies, sensitivity to food additives, or the body's inability to break down certain components in food. Identifying the specific foods that trigger intolerance can be challenging, as symptoms may not appear immediately after consumption and can vary from person to person.
On the other hand, food allergies involve an immune system response triggered by specific proteins present in certain foods. Unlike food intolerance, food allergies are characterized by an abnormal reaction of the immune system. When someone with a food allergy ingests a triggering food, their immune system recognizes the specific protein as a threat and releases chemicals, such as histamine, to fight it off. This immune response can lead to a range of symptoms observed in food allergy reactions, including skin rashes, itching, swelling, difficulty breathing, and even anaphylaxis, which is a severe and potentially life-threatening allergic reaction.
The Role of IgG and IgG4 in Food Intolerance
When it comes to food intolerance, the antibodies IgG and IgG4 play a crucial role. These antibodies are produced by the immune system in response to the presence of certain food components. Elevated levels of IgG and IgG4 indicate the possibility of a food intolerance, suggesting that the body may have an inflammatory response to those particular foods.
Research on IgG-based food intolerance testing is ongoing, and its accuracy and clinical significance are still debated among medical professionals. Some studies suggest that elevated levels of IgG antibodies may indicate a potential intolerance, while others argue that IgG antibodies are a normal immune response to food proteins and not necessarily indicative of an intolerance. Therefore, it is important to approach IgG-based testing with caution and consult with a healthcare professional for a comprehensive evaluation.
How Food Allergies Impact the Immune System
Food allergies involve a different immune system response mediated by IgE antibodies. When a person with a food allergy comes into contact with an allergenic food, their immune system reacts by producing IgE antibodies specific to that food. These IgE antibodies bind to immune cells, such as mast cells and basophils, which are responsible for releasing histamine and other chemicals in response to an allergen.
The release of histamine and other chemicals leads to the typical symptoms associated with food allergies, such as skin reactions (hives, itching), gastrointestinal symptoms (nausea, vomiting, diarrhea), respiratory symptoms (wheezing, coughing, shortness of breath), and cardiovascular symptoms (low blood pressure, rapid heartbeat). The severity of these symptoms can vary from mild to severe, with anaphylaxis being the most severe and potentially life-threatening allergic reaction.
It is important for individuals with food allergies to be vigilant about avoiding the allergenic foods and to carry emergency medication, such as epinephrine auto-injectors, in case of accidental exposure. Regular consultation with an allergist is crucial for proper diagnosis, management, and education on food allergies.

Exploring the ELISA Test
The Enzyme-Linked Immunosorbent Assay (ELISA) is another commonly used diagnostic test for detecting food allergies. This test measures the presence and levels of IgE antibodies, specifically targeting allergenic proteins in foods.
The Process and Purpose of the ELISA Test
During an ELISA test, blood samples are collected and exposed to specific food allergens. If a person is allergic to any of these foods, their blood will contain IgE antibodies that bind to the allergenic proteins. The ELISA test then measures the level of these bound antibodies, providing valuable information about food allergies.
Let's dive deeper into the process of the ELISA test. Firstly, a healthcare professional will collect a blood sample from the individual suspected of having a food allergy. This blood sample is then taken to a laboratory, where it undergoes a series of steps to detect the presence of IgE antibodies.
Once in the laboratory, the blood sample is centrifuged to separate the serum from the other components of blood. The serum, which contains the antibodies of interest, is then carefully extracted for further analysis.
Next, the extracted serum is mixed with specific allergenic proteins that are known to cause food allergies. These proteins act as bait, attracting the IgE antibodies present in the serum. If the person is allergic to any of the food allergens used in the test, their IgE antibodies will bind to these proteins.
After allowing sufficient time for the antibodies to bind to the allergenic proteins, the mixture is washed to remove any unbound antibodies or other substances. This step ensures that only the IgE antibodies specifically targeting the allergenic proteins are retained.
Finally, an enzyme-linked secondary antibody is added to the mixture. This secondary antibody recognizes and binds to the IgE antibodies that are already bound to the allergenic proteins. The enzyme linked to the secondary antibody catalyzes a reaction that produces a detectable signal, indicating the presence and level of IgE antibodies in the sample.
Advantages and Disadvantages of the ELISA Test
One of the advantages of the ELISA test is its high sensitivity in detecting specific IgE antibodies, making it an effective tool for diagnosing food allergies. By measuring the levels of these antibodies, healthcare professionals can determine the severity of the allergic reaction and guide appropriate treatment plans.
Moreover, the ELISA test is widely available and cost-effective compared to other diagnostic methods. Its simplicity and accuracy make it a preferred choice for many healthcare providers when assessing food allergies.
However, the ELISA test has certain limitations. It does not assess IgG or IgG4 antibodies, which play a significant role in food intolerances. While IgE antibodies are responsible for immediate allergic reactions, IgG and IgG4 antibodies are involved in delayed food hypersensitivity reactions. Therefore, the ELISA test may not provide a complete picture of an individual's immune response to certain foods.
Additionally, false positive results can occur with the ELISA test. Factors such as cross-reactivity with other proteins or non-specific binding can lead to incorrect interpretations. Therefore, further testing and clinical correlation are necessary to confirm the presence of a true food allergy when a positive result is obtained.
In conclusion, the ELISA test is a valuable tool in diagnosing food allergies by measuring the levels of IgE antibodies that specifically target allergenic proteins. While it has its advantages, such as high sensitivity and cost-effectiveness, it also has limitations, including the inability to assess IgG and IgG4 antibodies and the potential for false positive results. Healthcare professionals must consider these factors when interpreting the results of an ELISA test and make informed decisions regarding patient care.
