Food Allergy and Sensitivity Testing (FAST 88 Foods: IgE with IgG4) by Infinite Allergy Labs Vs Genomic Testing
Food allergies and sensitivities can cause a variety of symptoms and have become a growing concern in recent years. With the increasing number of people affected, there is a need for accurate and reliable testing methods to identify these allergies and sensitivities. In this article, we will explore two popular testing options: FAST 88 Foods: IgE with IgG4 by Infinite Allergy Labs and genomic testing.
Understanding Food Allergies and Sensitivities
Before we delve into the specifics of the testing methods, let's first understand what food allergies and sensitivities are. Food allergies occur when the body's immune system mistakenly identifies certain proteins in food as harmful invaders and triggers an immune response. This response can range from mild symptoms like hives and itching to severe ones like difficulty breathing and anaphylaxis.
Food allergies are more common in children than in adults, with some allergies being outgrown as the child grows older. However, certain allergies, such as peanut allergies, tend to persist into adulthood. It is important for individuals with food allergies to avoid consuming the allergenic food and to carry an epinephrine auto-injector in case of accidental exposure, as anaphylaxis can be life-threatening.
On the other hand, food sensitivities, also known as food intolerances, do not involve the immune system. They occur when the body has difficulty digesting certain types of food, leading to uncomfortable symptoms such as bloating, diarrhea, or nausea. While not life-threatening like allergies, food sensitivities can still significantly impact an individual's quality of life.
Food sensitivities can be caused by various factors, including enzyme deficiencies, chemical sensitivities, or even psychological factors. For example, lactose intolerance is a common food sensitivity that occurs when the body lacks the enzyme lactase, which is needed to break down lactose, the sugar found in milk and dairy products.
In addition to lactose intolerance, other common food sensitivities include gluten sensitivity, which is the inability to digest gluten, a protein found in wheat, barley, and rye. This sensitivity can lead to symptoms such as abdominal pain, bloating, and fatigue. Another example is histamine intolerance, where the body has difficulty breaking down histamine, a compound found in certain foods like aged cheese, fermented products, and alcohol. This can result in symptoms such as headaches, skin rashes, and nasal congestion.
Identifying food sensitivities can be challenging as the symptoms can be vague and vary from person to person. Elimination diets, where specific foods are removed from the diet and then reintroduced one at a time, can help identify trigger foods. Additionally, there are specialized tests available, such as blood tests and skin prick tests, that can assist in diagnosing food sensitivities.
It is important to note that food allergies and sensitivities are different from food intolerances, which are typically caused by the body's inability to digest certain substances, such as lactose or fructose. Food intolerances can also lead to uncomfortable symptoms, but they do not involve the immune system.
An Overview of Food Allergy and Sensitivity Testing
Now that we have a better understanding of food allergies and sensitivities, let's explore why testing for them is crucial. Accurate testing helps identify specific trigger foods, eliminating guesswork and allowing individuals to make informed dietary choices. It can also prevent potentially serious allergic reactions by avoiding exposure to allergens.
One of the most common methods used for food allergy and sensitivity testing is the skin prick test. This test involves placing a small amount of the suspected allergen on the skin and then pricking or scratching the skin's surface. If a person is allergic to the substance, a small raised bump, similar to a mosquito bite, will appear at the site of the test. This method is quick and relatively painless, making it a popular choice for many individuals.
Blood tests, such as the specific IgE blood test, are another common method for identifying food allergies and sensitivities. These tests measure the levels of specific antibodies in the blood that are associated with allergic reactions. By analyzing the antibody levels, healthcare professionals can determine if a person is allergic to certain foods. Blood tests are particularly useful for individuals who cannot undergo skin prick tests due to skin conditions or medications that may interfere with the results.
In some cases, healthcare professionals may recommend an elimination diet to identify trigger foods. This involves removing certain foods from the diet for a period of time and then reintroducing them one by one to observe any adverse reactions. This method can be time-consuming and requires careful monitoring of symptoms, but it can provide valuable insights into food sensitivities that may not be detected through other testing methods.
For individuals with more complex allergies or sensitivities, a food challenge may be necessary. This involves consuming small amounts of the suspected allergen under medical supervision to determine if a reaction occurs. Food challenges are typically conducted in a controlled environment, such as a hospital or clinic, to ensure immediate access to emergency medical care if needed.
It's important to note that each method of food allergy and sensitivity testing has its own advantages and limitations. The choice of test will depend on various factors, including the individual's medical history, symptoms, and the suspected allergens. Consulting with a healthcare professional is essential to determine which test is most appropriate for individual circumstances.

It cannot diagnose true allergies, as only an allergist can make an official diagnosis based on clinical history, physical examination, and additional tests if deemed necessary. Additionally, some scientific studies question the clinical relevance of IgG4 testing in identifying food sensitivities.
Introduction to Genomic Testing for Food Allergies and Sensitivities
Genomic testing takes a different approach to food allergy and sensitivity testing. Instead of focusing on immune response, it explores an individual's genetic makeup to identify potential risks and predispositions to certain food allergies.
Genomic testing analyzes an individual's DNA to identify gene variations associated with food allergies and sensitivities. By understanding a person's genetic predisposition, this testing method can provide insights into the likelihood of developing allergies and sensitivities. It can also determine which specific foods might pose a higher risk.
Like any testing method, genomic testing has both pros and cons. One of its significant advantages is its ability to detect potential risks before symptoms manifest. This early identification can help individuals take proactive measures to prevent the development of allergies or sensitivities. However, genomic testing is not diagnostic and cannot definitively determine if an allergy or sensitivity exists.
