Wheat G15

The IntroLab in Belgrade offers the Wheat G15 test to assess wheat allergy. This test measures specific IgE antibodies to wheat proteins, allowing doctors to accurately determine the level of allergic reaction in individuals exposed to wheat products.

What is the Wheat G15 test?

The Wheat G15 test is a specific IgE test that measures the amount of IgE antibodies in the blood, targeting wheat proteins. IgE antibodies are immune markers that activate in individuals with allergies when they come into contact with certain allergens. The test results indicate the level of the body’s sensitivity to wheat allergens, helping confirm the diagnosis of wheat allergy.

Understanding wheat allergy

Wheat allergy is an immune response to wheat proteins, such as albumins, globulins, gliadin, and glutenin. This allergy can cause symptoms of varying severity, depending on individual sensitivity and the type of exposure to wheat products.

Main symptoms of wheat allergy:

• Respiratory symptoms: sneezing, runny nose, nasal itching, difficulty breathing, cough
• Digestive symptoms: nausea, stomach pain, vomiting, diarrhea
• Skin symptoms: redness, itching, rash, or hives
• Anaphylaxis: in rare cases, a serious allergic reaction requiring immediate medical attention

Who should take the Wheat G15 test?

The test is recommended for individuals who:

• Show allergy symptoms after consuming wheat-containing products, such as bread, pasta, and pastries
• Experience respiratory allergy symptoms when in contact with flour or while in bakeries
• Suspect a wheat allergy due to frequent skin rashes or digestive issues after consuming wheat products
• Have a family history of allergies and wish to check for a specific reaction to wheat

Difference between wheat allergy and gluten intolerance

It is essential to distinguish wheat allergy from gluten intolerance (celiac disease). Celiac disease is an autoimmune condition where the body reacts to gluten, a protein found in wheat, barley, and rye. Wheat allergy, however, is not specifically directed at gluten and may involve various wheat proteins. Additionally, wheat allergy symptoms can be acute and may include anaphylaxis, while celiac disease presents chronic gastrointestinal symptoms and requires strict gluten avoidance.

Understanding Wheat G15 test results

The test results indicate levels of IgE antibodies specific to wheat, classified into three levels:

• Low level: Indicates a mild or non-existent allergic reaction to wheat
• Moderate level: Suggests a moderate allergic reaction, with dietary avoidance of wheat recommended
• High level: Indicates a severe allergic reaction; complete avoidance of wheat and wheat-containing products is advised

Recommended measures for people with wheat allergy

Individuals with a confirmed wheat allergy can take the following steps:

• Avoid wheat in the diet: Switch to wheat-free foods, using alternatives such as rice, oats (if certified gluten-free), corn, and other grains that do not trigger allergies.
• Read labels carefully: Check product ingredients, as wheat can be hidden in various processed foods.
• Inform restaurants: Notify restaurant staff about a wheat allergy to prevent accidental contamination.
• Use antihistamines and other medications: These medications can help relieve symptoms, while an epinephrine injector (Epipen) may be necessary in case of severe reactions.
• Education and support: Understanding the allergy and possible sources of wheat in the diet, as well as consulting with a doctor or allergist about avoidance strategies, can be crucial for allergy management.

Is it possible to cure wheat allergy?

Like most food allergies, wheat allergy usually cannot be entirely cured, but symptoms can be managed. The most effective strategy is avoiding wheat, and in some cases, immunotherapy is used to reduce sensitivity.
