Food Allergy and Sensitivity Testing (FAST 88 Foods:IgE/IgG4 & IgG) by Infinite Allergy Labs Vs RAST Test
Food allergies and sensitivities can greatly impact a person's quality of life. The symptoms can range from mild discomfort to severe reactions that require immediate medical attention. For those who suspect they have a food allergy or sensitivity, accurate testing is crucial in order to identify the culprit and make necessary dietary adjustments. In this article, we will explore two common types of food allergy testing: the FAST 88 Foods:IgE/IgG4 & IgG Test by Infinite Allergy Labs and the RAST Test.
Understanding Food Allergies and Sensitivities
Before diving into the specifics of these tests, it's important to have a basic understanding of food allergies and sensitivities. Both conditions involve adverse reactions to certain foods, but there are some differences between them.
Food allergies are immune system responses triggered by specific proteins in certain foods. When a person with a food allergy consumes the offending food, their immune system overreacts and produces antibodies called immunoglobulin E (IgE) that can cause various symptoms ranging from hives and itching to more severe reactions like anaphylaxis.
For example, let's say someone with a peanut allergy accidentally ingests peanuts. Their immune system recognizes the proteins in peanuts as harmful invaders and launches an attack by releasing IgE antibodies. These antibodies trigger the release of chemicals like histamine, which leads to the symptoms commonly associated with food allergies.
On the other hand, food sensitivities are non-immune responses to certain foods. These reactions can be triggered by a variety of factors, such as enzyme deficiencies, chemical sensitivities, or intolerances to food components like lactose. Symptoms of food sensitivities are often less severe than those of food allergies and may include digestive issues, headaches, and skin problems.
Let's take lactose intolerance as an example of a food sensitivity. Lactose intolerance occurs when the body lacks the enzyme lactase, which is needed to break down lactose, the sugar found in milk and dairy products. When a person with lactose intolerance consumes lactose-containing foods, they may experience symptoms like bloating, gas, and diarrhea. These symptoms occur because the undigested lactose ferments in the gut, leading to discomfort.
Common Symptoms of Food Allergies and Sensitivities
The symptoms of food allergies and sensitivities can vary widely from person to person. Some common symptoms of food allergies include:
- Hives or rash: These can appear as itchy, raised bumps on the skin and may be accompanied by redness.
- Swelling of the lips, tongue, or throat: This swelling, known as angioedema, can cause difficulty in breathing or swallowing.
- Shortness of breath or wheezing: These respiratory symptoms can be a sign of a severe allergic reaction.
- Nausea, vomiting, or diarrhea: These digestive symptoms can occur shortly after consuming the allergenic food.
- Abdominal pain or cramping: These discomforting sensations may accompany other digestive symptoms.
On the other hand, symptoms of food sensitivities may include:
- Headaches or migraines: These can range from mild to severe and may be triggered by certain foods.
- Skin issues (eczema, rashes, etc.): Food sensitivities can contribute to skin problems like redness, itching, or inflammation.
- Digestive problems (bloating, gas, etc.): Sensitivities to certain foods can lead to digestive discomfort and irregularities.
- Fatigue or brain fog: Some individuals may experience a decrease in energy levels or difficulty concentrating after consuming trigger foods.
- Joint pain or inflammation: Inflammation caused by food sensitivities can contribute to joint discomfort and stiffness.
It's important to note that these symptoms are not exclusive to food allergies or sensitivities, and other medical conditions can cause similar manifestations. If you suspect you have a food allergy or sensitivity, it's best to consult with a healthcare professional for proper diagnosis and guidance.
An Overview of Food Allergy Testing
When it comes to diagnosing food allergies and sensitivities, testing is essential. Not only does it confirm the presence of an allergy or sensitivity, but it also helps identify the specific food triggers. This information is crucial for developing an effective treatment plan.
Food allergy testing is a complex process that involves various methods and techniques to accurately identify and diagnose allergies and sensitivities. It is a vital step in understanding the body's immune response to certain foods and can greatly improve the quality of life for individuals suffering from food-related symptoms.
