"I simply ordered the test online, received it in the mail a few days later, and took the test in the comfort of my own home using a quick finger prick. The instructions were clear and easy to follow, and the process itself was quick and painless."

Food specific IgG

Immunoglobulin E is a type of antibody, which is produced by the body if exposed to an allergen. These proteins help the body fight bacteria and germs. The body produces these antibodies as a reaction to any harmless substance such as food. The symptoms of having an allergic reaction are varied and can be an irritation caused to the nose, throat or lungs or other signs. Allergic reactions could be mild or severe and in rare cases, they can also be life-threatening.

If the test indicates a high level of IgE antibodies, it is most likely that you are allergic to the substance that has been tested for.

Additional Information

If you suspect that you may be intolerant to certain foods, you may want to consider getting a food intolerance test. These tests can help you determine which foods your body has difficulty digesting or absorbing.

Home Food Intolerance Test

There are several different types of food intolerance tests. Each has its own advantages and disadvantages, so it is important to choose the right one for you. One type of test is called an elimination diet. This involves removing all potential allergens from your diet for a period of time and then slowly reintroducing them one at a time. This can be a very effective way to identify food intolerances, but it can be difficult to stick to such a strict diet. Another option is a skin prick test. This test is performed by pricking the skin with a needle that has been dipped in a solution containing a potential allergen. If you are allergic to that food, you will have a reaction on the spot where the needle was inserted. This test is relatively easy to perform and can be used to detect food allergies and intolerances.

A blood test is another option for determining food intolerance. This test measures the amount of IgG antibodies in your blood. IgG antibodies are produced in response to foods that your body perceives as being harmful. A high level of IgG antibodies may indicate that you are intolerant to that food.Finally, there is the hydrogen breath test. This test measures the amount of hydrogen gas in your breath. Hydrogen gas is produced when your body breaks down certain carbohydrates. A high level of hydrogen gas in your breath may indicate that you are intolerant to those carbohydrates.

No matter which test you choose, it is important to work with a qualified healthcare professional to interpret the results. They can help you determine whether or not you have a food intolerance and make dietary changes accordingly. With the right diagnosis and treatment, you can minimize the symptoms of food intolerance and live a healthier life.

Food intolerance is a condition that affects people's digestive systems. It occurs when the body has difficulty digesting certain foods, causing uncomfortable symptoms like bloating, gas, and diarrhoea. While food intolerance is not as serious as food allergies, it can still be very unpleasant and make it difficult to eat certain foods.

There are several different types of food intolerance, including lactose intolerance, gluten sensitivity, and fructose malabsorption. Lactose intolerance is the most common type, and occurs when people have difficulty digesting lactose, a sugar found in milk and other dairy products. Gluten sensitivity is a condition that affects the digestive system and causes uncomfortable symptoms like bloating, gas, and diarrhoea after eating foods containing gluten. Fructose malabsorption is a condition that occurs when people have difficulty digesting fructose, a sugar found in fruits and vegetables.

If you think you may have a food intolerance, talk to your doctor. There are several tests that can be done to determine which foods you are intolerant to. Once you know which foods to avoid, it will be easier to manage your symptoms. There are also several different types of dietary supplements that can help ease the symptoms of food intolerance. Talk to your doctor or a nutritionist about which supplements may be right for you.

Why take a test?

The Food Intolerance test will detect if you have any allergy to common food items such as tea, coffee, cow milk, pork, egg white, egg yolk, almond, wheat, gluten, oat and more specific food.
