Food Allergy and Sensitivity Testing (FAST 88 Foods: IgG with C3d/C3b) by Infinite Allergy Labs Vs Allergen-Specific IgE Blood Testing
In recent years, the prevalence of food allergies and sensitivities has been on the rise. It is estimated that up to 15 million Americans have some form of food allergy, with the most common triggers being peanuts, tree nuts, milk, eggs, wheat, soy, fish, and shellfish. Food allergies can cause a wide range of symptoms, ranging from mild gastrointestinal discomfort to severe allergic reactions that can be life-threatening.
Understanding Food Allergies and Sensitivities
Food allergies and sensitivities are common conditions that can have a significant impact on a person's health and well-being. It is important to understand the differences between these two conditions in order to properly manage and address them.
What are Food Allergies?
Food allergies occur when the immune system reacts abnormally to certain proteins found in food. This immune response is triggered by the ingestion of the specific food and can result in a range of symptoms. When someone with a food allergy consumes a particular food, their immune system mistakenly identifies it as harmful and produces an antibody called immunoglobulin E (IgE) to fight against it.
Once the IgE antibodies are produced, they trigger the release of chemicals, such as histamine, in the body. This release of chemicals can cause various symptoms, including hives, swelling, itching, and in severe cases, anaphylaxis. Anaphylaxis is a severe and potentially life-threatening allergic reaction that can affect multiple organs in the body, leading to difficulty breathing, a drop in blood pressure, and loss of consciousness.
Food allergies can be triggered by a wide range of foods, including nuts, shellfish, eggs, and dairy products. It is important for individuals with food allergies to carefully read food labels and avoid consuming foods that may contain allergens. In some cases, even trace amounts of the allergen can trigger a severe allergic reaction, so strict avoidance is necessary.
Understanding Food Sensitivities
Food sensitivities, also known as food intolerances, are different from food allergies. While food allergies involve the immune system, food sensitivities typically do not. Food sensitivities are usually triggered by the body's inability to digest certain components of food, such as lactose or gluten.
When someone has a food sensitivity, their body lacks the necessary enzymes or chemicals to break down and absorb specific components of food. This can lead to a range of symptoms that are often milder than those experienced in food allergies. Common symptoms of food sensitivities include bloating, gas, diarrhea, or stomach cramps.
One of the most well-known food sensitivities is lactose intolerance, which occurs when the body lacks the enzyme lactase needed to break down lactose, the sugar found in milk and dairy products. This can cause digestive symptoms such as bloating, gas, and diarrhea when lactose-containing foods are consumed.
Similarly, gluten sensitivity or intolerance is another common food sensitivity. People with gluten sensitivity experience digestive symptoms and discomfort when they consume foods that contain gluten, a protein found in wheat, barley, and rye.
It is important to note that food sensitivities can vary in severity and individual tolerance. Some individuals may be able to tolerate small amounts of the offending component without experiencing symptoms, while others may need to completely avoid it.
Consulting with a healthcare professional, such as an allergist or gastroenterologist, can help individuals determine if they have a food allergy or sensitivity. Proper diagnosis and understanding of these conditions are crucial for managing symptoms and maintaining a healthy diet.
An Overview of Food Allergy and Sensitivity Testing
The Importance of Testing for Food Allergies and Sensitivities
Accurate diagnosis of food allergies and sensitivities is crucial in order to effectively manage and avoid triggering foods. This is where food allergy and sensitivity testing comes into play. Testing can help identify specific food allergens or sensitivities, enabling individuals to make informed dietary choices and take appropriate measures to prevent adverse reactions.
Food allergies and sensitivities can manifest in a variety of ways, ranging from mild discomfort to life-threatening anaphylactic reactions. It is estimated that approximately 32 million Americans have food allergies, with children being the most affected group. Identifying and understanding these allergies and sensitivities is essential for maintaining a healthy and safe lifestyle.
Food allergy testing is particularly important for individuals who experience recurrent symptoms such as hives, swelling, itching, gastrointestinal distress, or respiratory issues after consuming certain foods. By pinpointing the specific allergens responsible for these reactions, individuals can avoid potential triggers and minimize the risk of experiencing adverse effects.
Common Methods of Food Allergy and Sensitivity Testing
There are several methods available for food allergy and sensitivity testing. Two of the most commonly used tests are the FAST 88 Foods: IgG with C3d/C3b test by Infinite Allergy Labs and the Allergen-Specific IgE blood testing. Let's explore each of these tests in more detail.
The FAST 88 Foods: IgG with C3d/C3b test is a comprehensive food sensitivity test that analyzes the levels of IgG antibodies and complement proteins C3d/C3b in response to 88 different foods. This test provides a detailed report on the individual's immune response to specific foods, helping to identify potential sensitivities. By understanding these sensitivities, individuals can make personalized dietary adjustments to alleviate symptoms and improve overall well-being.
Allergen-Specific IgE blood testing, on the other hand, focuses on identifying specific allergies by measuring the levels of IgE antibodies in response to specific food allergens. This test is particularly useful for diagnosing immediate allergic reactions, such as hives, swelling, or anaphylaxis, which occur shortly after consuming certain foods. By identifying the specific allergens responsible for these reactions, individuals can take necessary precautions to avoid those foods and prevent severe allergic episodes.
It is worth noting that while these tests can provide valuable insights into food allergies and sensitivities, they should always be interpreted in conjunction with an individual's clinical history and symptoms. Working closely with a healthcare professional, such as an allergist or immunologist, is essential for accurate diagnosis and appropriate management of food allergies and sensitivities.

What is FAST 88 Foods: IgG with C3d/C3b Test?
The FAST 88 Foods: IgG with C3d/C3b test is a comprehensive food allergy and sensitivity testing panel offered by Infinite Allergy Labs. This test measures the levels of immunoglobulin G (IgG) antibodies, along with complement proteins C3d and C3b, in response to 88 common foods. These antibodies are produced as a result of exposure to certain foods and can indicate potential food allergies or sensitivities.
How Does the Test Work?
The FAST 88 Foods test involves a simple blood draw, which is then analyzed in a laboratory. The blood sample is exposed to the 88 foods included in the panel, and the levels of IgG antibodies and complement proteins are measured. The results are typically reported as a quantitative value, indicating the level of reactivity to each tested food.
Benefits and Limitations of the FAST 88 Foods Test
One of the key benefits of the FAST 88 Foods test is its comprehensive nature, as it assesses reactions to a wide range of commonly consumed foods. This can be particularly helpful for individuals with symptoms that are difficult to pinpoint or those who suspect multiple food sensitivities. Moreover, the inclusion of complement proteins C3d and C3b provides additional insight into the immune response.
However, it is important to note that the FAST 88 Foods test is not intended for the diagnosis of immediate IgE-mediated food allergies, which are typically tested using other methods, such as skin prick tests or allergen-specific IgE blood testing.
Allergen-Specific IgE Blood Testing: A Detailed Review
Understanding Allergen-Specific IgE Blood Testing
Allergen-Specific IgE blood testing is another commonly used method for diagnosing food allergies. This test measures the levels of specific IgE antibodies in response to individual food allergens. It is often used to confirm suspected IgE-mediated food allergies, which can cause immediate allergic reactions upon exposure to the allergenic food.
The Procedure of Allergen-Specific IgE Blood Testing
Similar to the FAST 88 Foods test, allergen-specific IgE blood testing requires a blood sample. However, instead of testing for a panel of foods, this test focuses on specific allergens. A healthcare professional will draw blood and send it to a laboratory, where it will be analyzed for the presence of IgE antibodies against the suspected food allergens.
Pros and Cons of Allergen-Specific IgE Blood Testing
One major advantage of allergen-specific IgE blood testing is its ability to confirm immediate IgE-mediated food allergies, which can be life-threatening. This test can provide quantitative results, helping to determine the likelihood and severity of an allergic reaction. However, it is important to note that this test does not assess non-IgE mediated food sensitivities, and false positives and false negatives can occur.
