Biomarkers

Food specific IgG
Here’s an improved version of the text with clearer structure, better flow, and enhanced readability:

Immunoglobulin E (IgE) is a type of antibody that the body produces in response to exposure to allergens. These proteins play a role in defending the body against bacteria and germs. However, IgE antibodies are often triggered by harmless substances, such as certain foods, leading to an allergic reaction.

Symptoms of an allergic reaction can vary widely and may include irritation in the nose, throat, or lungs, as well as other signs. Reactions can range from mild to severe, and in rare cases, they can become life-threatening.

If a test shows a high level of IgE antibodies, it strongly suggests that you are allergic to the substance being tested.

Additional Information
Understanding Food Intolerances and Testing Options

If you suspect you may be intolerant to certain foods, a food intolerance test can help identify which foods are difficult for your body to digest or absorb. Food intolerances can cause uncomfortable symptoms, including bloating, gas, and diarrhea, and identifying the cause is the first step to managing your symptoms.

Types of Food Intolerance Tests

There are several types of food intolerance tests, each with its own benefits and limitations. Here’s a breakdown of the most common options:

Elimination Diet

An elimination diet involves removing potential allergens from your diet for a period of time, followed by a gradual reintroduction of foods to observe reactions. While this method can be highly effective, it requires discipline and careful planning to avoid accidental exposure.

Skin Prick Test

A skin prick test involves pricking the skin with a needle containing a potential allergen solution. If you’re intolerant to the food, you’ll experience a reaction at the site. This test is relatively simple and can detect both allergies and intolerances.

Blood Test

A blood test measures the level of IgG antibodies produced by your body in response to certain foods. Elevated IgG levels may suggest a food intolerance. This test is useful for detecting delayed food reactions.

Hydrogen Breath Test

The hydrogen breath test measures the amount of hydrogen gas in your breath after consuming specific carbohydrates. A high hydrogen level indicates difficulty in digesting certain sugars, like fructose or lactose, pointing to a possible intolerance.

Working with a Healthcare Professional

Regardless of which test you choose, it’s essential to work with a qualified healthcare provider to interpret the results. A professional can guide you on eliminating intolerant foods from your diet and help manage symptoms effectively. With the right diagnosis, you can make informed dietary choices and improve your quality of life.

Types of Food Intolerances

Food intolerance occurs when your digestive system struggles to process specific foods. This can lead to discomfort but is less severe than food allergies. Common types of food intolerances include:

Lactose Intolerance: Difficulty digesting lactose, a sugar in milk and dairy products, causing symptoms like bloating and diarrhea.
Gluten Sensitivity: Digestive discomfort after consuming gluten, a protein found in wheat, barley, and rye.
Fructose Malabsorption: Difficulty digesting fructose, a sugar found in fruits and certain vegetables, leading to bloating and gas.
Managing Food Intolerances

If you suspect a food intolerance, it’s important to consult your doctor. They can recommend appropriate tests to identify the specific foods causing discomfort. Once you know which foods to avoid, managing your symptoms becomes easier. Additionally, dietary supplements may help alleviate some of the discomfort associated with food intolerances. Consult with your doctor or a nutritionist to find the right supplements for your needs.

Why take a test?

The Food Intolerance Test helps identify sensitivities to common foods and ingredients, including tea, coffee, cow’s milk, pork, egg whites, egg yolks, almonds, wheat, gluten, oats, and many others. It can also detect intolerance to specific foods such as beef, chicken, lamb, cod, salmon, shrimp, crab, casein, spelt, rye, rice, potatoes, hazelnuts, peanuts, soy, walnuts, mustard, and a variety of fruits and vegetables, including apples, oranges, strawberries, kiwis, peaches, bananas, tomatoes, carrots, celery, onions, and more. Additionally, the test can detect sensitivities to gluten, coffee, sesame, black pepper, and baker’s yeast.
