Food allergies and sensitivities can have a significant impact on an individual's health and well-being. Identifying and understanding these allergies and sensitivities is crucial in managing and avoiding potential reactions. This article will provide an in-depth examination of two widely used food allergy and sensitivity tests: FAST 88 Foods: IgG by Infinite Allergy Labs and the ELISA Test. By comparing these tests, we aim to assist individuals in making informed decisions about which approach best suits their needs.
Understanding Food Allergies and Sensitivities
What are Food Allergies?
Food allergies occur when the immune system reacts abnormally to certain proteins found in specific foods. These reactions can range from mild discomfort to severe allergic responses that require immediate medical attention. Peanut, tree nut, egg, milk, and fish allergies are among the most common.
When someone with a food allergy consumes the allergenic food, their immune system mistakenly identifies the proteins as harmful invaders. In response, the body releases chemicals like histamine, which triggers a cascade of symptoms. These symptoms can vary widely from person to person and can affect different body systems.
For some individuals, exposure to even trace amounts of the allergenic food can lead to a life-threatening reaction called anaphylaxis. Anaphylaxis is a severe allergic response that can cause difficulty breathing, a drop in blood pressure, and loss of consciousness. Immediate medical attention, usually in the form of an epinephrine injection, is crucial to prevent fatalities.
The Impact of Food Sensitivities
On the other hand, food sensitivities involve adverse reactions to food that do not involve the immune system. Symptoms may include gastrointestinal issues, headaches, skin problems, and fatigue. Unlike food allergies, sensitivities often have delayed onset, making them challenging to identify without appropriate testing.
Food sensitivities can be caused by various factors, including enzyme deficiencies, chemical additives, or naturally occurring compounds in food. One common example is lactose intolerance, where individuals lack the enzyme lactase needed to break down lactose, the sugar found in milk and dairy products. This inability to digest lactose can lead to digestive discomfort, bloating, and diarrhea.
Identifying food sensitivities can be a complex process. Elimination diets, where suspected trigger foods are removed from the diet for a period of time, can help pinpoint the culprits. Additionally, medical professionals may recommend specialized tests, such as blood tests or skin prick tests, to determine specific sensitivities.
It's important to note that while food allergies and sensitivities can cause significant discomfort, they are different from food intolerances. Food intolerances typically involve difficulty digesting certain foods due to enzyme deficiencies or other digestive issues, rather than an immune system response.
An Introduction to Food Allergy and Sensitivity Testing
The Importance of Testing
Accurate testing is essential in diagnosing food allergies and sensitivities. Identifying trigger foods is crucial in managing symptoms and developing personalized dietary plans. Food allergies and sensitivities can cause a wide range of symptoms, including digestive issues, skin rashes, respiratory problems, and even life-threatening anaphylaxis. By undergoing proper testing, individuals can gain a better understanding of their specific food sensitivities and allergies, leading to improved quality of life and overall health.
When it comes to food allergies, testing is especially important because even a small amount of the allergen can trigger a severe reaction. For instance, someone with a peanut allergy may experience a life-threatening reaction if they unknowingly consume a food that has been cross-contaminated with peanuts. By identifying and avoiding these trigger foods, individuals can significantly reduce their risk of experiencing an allergic reaction.
Common Methods of Testing
Several methods are used to detect food allergies and sensitivities. These methods vary in terms of their accuracy, invasiveness, and cost. It is important to consult with a healthcare professional to determine the most appropriate testing method for each individual.
Skin Prick Tests: This is one of the most common methods used to diagnose food allergies. During a skin prick test, small amounts of different allergens are applied to the skin, usually on the forearm or back. The skin is then pricked with a small needle, allowing the allergens to enter the body. If a person is allergic to a particular food, they will develop a small raised bump or hive at the site of the prick.
Blood Tests: Blood tests are another common method of testing for food allergies and sensitivities. These tests measure the levels of specific antibodies, such as IgE or IgG, in the blood. IgE antibodies are associated with immediate allergic reactions, while IgG antibodies are associated with delayed reactions. Blood tests can provide valuable information about which foods may be triggering an immune response in the body.
Elimination Diets: Elimination diets involve removing certain foods or food groups from the diet for a period of time and then reintroducing them one by one to determine if any symptoms occur. This method can be helpful in identifying trigger foods, especially in cases where other testing methods have been inconclusive.
Oral Food Challenges: Oral food challenges are typically conducted under medical supervision. During this test, the individual consumes small amounts of the suspected allergen, gradually increasing the dose over time. This method is considered the gold standard for diagnosing food allergies, as it provides the most accurate results. However, it should only be done under the guidance of a healthcare professional, as it carries the risk of triggering a severe allergic reaction.
Overall, food allergy and sensitivity testing plays a crucial role in identifying trigger foods and managing symptoms. By undergoing proper testing, individuals can make informed decisions about their diet, leading to improved health and well-being.

An Overview of the ELISA Test
The Enzyme-Linked Immunosorbent Assay (ELISA) is a widely used method for detecting food allergies and sensitivities. This test is designed to measure the presence and quantity of specific IgE antibodies, which are produced by the immune system in response to allergens.
Understanding the ELISA Test
The ELISA test plays a crucial role in diagnosing food allergies by identifying the specific IgE antibodies that are associated with allergic reactions. These antibodies are produced by the immune system as a defense mechanism when it encounters an allergen. By measuring the levels of these antibodies, the ELISA test can determine if an individual has an allergic response to certain foods.
The Process of the ELISA Test
Similar to the FAST 88 Foods: IgG test, the ELISA test requires a blood sample. The blood sample is collected by a healthcare professional and then sent to a laboratory for analysis. In the lab, the sample is carefully evaluated to detect the presence of IgE antibodies specific to various food allergens.
The ELISA test involves a series of steps to accurately measure the IgE antibody levels. First, the blood sample is mixed with specific allergens that are known to trigger allergic reactions. These allergens are usually derived from common food sources such as peanuts, milk, eggs, and shellfish. If the individual is allergic to any of these foods, their blood will contain IgE antibodies that bind to the allergens.
Next, an enzyme-linked antibody is added to the mixture. This antibody binds to the IgE antibodies present in the blood sample, forming a complex. The enzyme attached to the antibody allows for the detection of this complex.
Finally, a substrate is added to the mixture, which reacts with the enzyme and produces a color change. The intensity of the color change is directly proportional to the amount of IgE antibodies present in the blood sample. This color change is then measured using a spectrophotometer, providing quantitative results.
Pros and Cons of the ELISA Test
The ELISA test offers several advantages in the diagnosis of food allergies. One significant advantage is its ability to detect immediate, IgE-mediated food allergies. This means that the ELISA test can identify allergies that cause immediate reactions, such as hives, swelling, or difficulty breathing, which can be life-threatening in some cases.
However, it is important to note that the ELISA test may not be as effective in identifying delayed onset food sensitivities that involve different immune mechanisms. Delayed onset food sensitivities are characterized by symptoms that appear several hours or even days after consuming the allergenic food. These sensitivities are often mediated by different types of immune cells or antibodies, which the ELISA test may not detect.
Furthermore, like other diagnostic tests, the ELISA test should be interpreted by a qualified healthcare professional who takes into account the individual's clinical history and symptoms. It is essential to consider the test results in conjunction with the person's overall health and medical background to make an accurate diagnosis.
In conclusion, the ELISA test is a valuable tool in the diagnosis of immediate IgE-mediated food allergies. It provides quantitative results by measuring the levels of specific IgE antibodies in the blood sample. However, it is important to recognize that the ELISA test may not be effective in identifying delayed onset food sensitivities, and its results should be interpreted by a healthcare professional in the context of the individual's clinical history and symptoms.
