Food Allergy and Sensitivity Testing (FAST 88 Foods: IgE with IgG4) by Infinite Allergy Labs Vs Blood Typing
Food allergies and sensitivities can cause a range of symptoms, from mild discomfort to life-threatening reactions. Identifying the specific foods that trigger these reactions is crucial for individuals seeking to manage their dietary choices and avoid potential health risks. There are various methods available for food allergy and sensitivity testing, each with its own merits and limitations. Two popular approaches include the Food Allergy and Sensitivity Testing (FAST 88 Foods: IgE with IgG4) offered by Infinite Allergy Labs and the traditional method of blood typing. In this article, we will explore the differences between these two testing methods, their effectiveness, and considerations for choosing the most appropriate approach.
Understanding Food Allergies and Sensitivities
Before diving into the specifics of the testing methods, it is important to grasp the concepts of food allergies and sensitivities. A food allergy occurs when the immune system mistakenly identifies a particular food as harmful, triggering an immune response. This response is mediated by immunoglobulin E (IgE), an antibody that recognizes and binds to allergenic proteins in food. In contrast, food sensitivities involve non-IgE mediated reactions to certain foods. These reactions are generally delayed and may manifest as digestive issues, headaches, or skin irritations.
Food allergies are a complex and fascinating area of study. The immune system, designed to protect the body from harmful invaders, can sometimes go awry and mistakenly identify harmless proteins in food as potential threats. This can lead to a range of symptoms, from mild discomfort to life-threatening reactions.
What is a Food Allergy?
A food allergy is an abnormal immune response to specific components in food. When someone with a food allergy consumes the trigger food, their immune system releases a surge of chemicals, such as histamine, which can cause symptoms ranging from rashes and itching to life-threatening anaphylaxis.
Anaphylaxis is a severe and potentially life-threatening allergic reaction that can occur within minutes of exposure to an allergen. It can cause difficulty breathing, a drop in blood pressure, and loss of consciousness. Prompt medical attention is crucial in such cases, as anaphylaxis can be fatal if left untreated.
Food allergies can be diagnosed through various methods, including skin prick tests, blood tests, and oral food challenges. These tests help identify the specific allergen causing the reaction, allowing individuals to avoid those foods and prevent future allergic reactions.
What is a Food Sensitivity?
A food sensitivity, also known as food intolerance, is characterized by the inability to properly digest certain foods. Unlike food allergies, food sensitivities do not involve the immune system. The symptoms of a food sensitivity can vary widely and may include bloating, abdominal pain, diarrhea, or headaches.
Food sensitivities are intriguing because they can be influenced by various factors, such as genetics, gut health, and environmental factors. Some individuals may experience temporary food sensitivities due to factors like stress or illness, while others may have lifelong sensitivities to certain foods.
Identifying food sensitivities can be challenging, as the symptoms are often delayed and not as immediately severe as those of food allergies. Elimination diets, where suspected trigger foods are removed from the diet and then gradually reintroduced, can help pinpoint the specific foods causing the sensitivity. Additionally, certain medical tests, such as lactose intolerance tests or breath tests, can provide further insights into food sensitivities.
It is important to note that food allergies and sensitivities are not the same as food preferences or aversions. While someone may choose to avoid certain foods for personal reasons, food allergies and sensitivities involve specific physiological reactions that can impact a person's health and well-being.

The Role of IgE and IgG4 in Food Allergies and Sensitivities
Understanding the contributions of IgE and IgG4 antibodies to food allergies and sensitivities is vital for interpreting test results and devising appropriate dietary strategies.
Food allergies and sensitivities have become increasingly prevalent in recent years, affecting millions of people worldwide. These conditions can range from mild to severe, with symptoms ranging from digestive issues to life-threatening anaphylaxis. In order to effectively manage and treat these conditions, it is important to understand the role that different types of antibodies play in the immune response to food.
Understanding IgE's Role in Allergic Reactions
IgE antibodies, also known as immunoglobulin E, are responsible for immediate allergic responses. When an individual with a food allergy consumes the allergenic food, the IgE antibodies bind to the food proteins and trigger the release of histamine and other chemicals. This cascade of events leads to the classic symptoms of allergic reactions, such as hives, itching, swelling, wheezing, and difficulty breathing.
It is important to note that IgE-mediated food allergies are typically rapid-onset and can occur within minutes to hours after consuming the allergenic food. The severity of the reaction can vary from person to person, with some individuals experiencing mild symptoms and others facing life-threatening anaphylaxis.
Diagnosing IgE-mediated food allergies often involves a combination of medical history, physical examination, and specific allergy tests, such as skin prick tests or blood tests. These tests measure the levels of IgE antibodies in the blood and help identify the specific foods that trigger an allergic response.
The Function of IgG4 in Food Sensitivities
IgG4 antibodies, on the other hand, are associated with delayed food sensitivities. While the exact mechanism is not yet fully understood, it is believed that IgG4 antibodies may play a role in modulating immune responses and contributing to inflammatory processes associated with food sensitivities.
Unlike IgE-mediated allergies, IgG4-mediated food sensitivities are characterized by delayed onset symptoms, often appearing hours to days after consuming the offending food. These symptoms can be diverse and vary from person to person, making it challenging to pinpoint the exact cause of the sensitivity.
Food sensitivity testing, which measures IgG4 antibody levels, can be helpful in identifying potential trigger foods. However, it is important to interpret these test results with caution, as elevated IgG4 levels do not necessarily indicate a true allergy. Instead, they suggest a possible sensitivity that may require further investigation and dietary modifications.
It is worth noting that the scientific community is still actively researching the role of IgG4 antibodies in food sensitivities. Some experts argue that IgG4-mediated reactions may be a secondary response to the underlying inflammation caused by other factors, such as gut dysbiosis or intestinal permeability. Further studies are needed to fully understand the complexity of IgG4-mediated food sensitivities and their clinical significance.
In conclusion, both IgE and IgG4 antibodies play important roles in food allergies and sensitivities. While IgE antibodies are responsible for immediate allergic reactions, IgG4 antibodies are associated with delayed food sensitivities. Understanding the functions and implications of these antibodies is crucial for accurate diagnosis and effective management of food-related immune responses.
Blood Typing: An Alternative Approach to Allergy Testing
Blood typing has long been utilized to determine an individual's blood group for transfusions and organ transplants. However, recent studies have investigated the potential of blood typing to identify potential food allergies and sensitivities.
The Science Behind Blood Typing for Allergies
The concept of blood typing for allergies is based on the principle that certain blood types may be more prone to developing allergies. By matching an individual's blood type with known allergenic foods associated with that blood type, it is believed that potential sensitivities can be identified.
Pros and Cons of Blood Typing
While blood typing provides a different perspective on identifying food sensitivities, it is important to consider its limitations. Blood typing for allergies is not as comprehensive as the FAST 88 Foods: IgE with IgG4 test, as it focuses solely on potential food reactions associated with specific blood types. Additionally, the scientific validity and reliability of this method are still being explored.
Comparing FAST 88 Foods: IgE with IgG4 and Blood Typing
When considering the most suitable testing method, several factors need to be taken into account, such as accuracy, reliability, cost, and accessibility.
Accuracy and Reliability
In terms of accuracy and reliability, the FAST 88 Foods: IgE with IgG4 test provides a more comprehensive assessment of both immediate IgE-mediated allergies and delayed IgG4-mediated sensitivities. Blood typing, on the other hand, relies on a theoretical connection between blood type and potential food reactions, making its accuracy and reliability less established.
Cost and Accessibility
Regarding cost and accessibility, the FAST 88 Foods: IgE with IgG4 test may require a higher investment than blood typing. However, the comprehensive nature of the test and its ability to identify a wide range of potential allergens make it a valuable option for individuals seeking a thorough assessment. Blood typing, on the contrary, may be more accessible and cost-effective but lacks the comprehensive analysis provided by the FAST 88 Foods test.
Ultimately, the choice between Infinite Allergy Labs' FAST 88 Foods: IgE with IgG4 test and blood typing depends on the individual's specific needs, preferences, and medical advice from healthcare professionals.
