Food Intolerance Test Overview

Food intolerance is a condition in which the body cannot properly digest certain foods. It can be caused by a variety of factors, including allergies, sensitivities, and food poisoning. Many people mistakenly believe that they have food intolerances based on vague symptoms such as diarrhea or bloating.

However, food intolerance testing is an important way to screenings for other conditions such as celiac disease or gluten sensitivity. Testing can also help identify specific foods that may cause problems for some individuals. Read on to know more about food intolerance tests.

What is it used for?

A food intolerance test is a type of blood test that can help determine if you have an allergy to a certain food. It's usually conducted by taking into account several factors, such as your diet and symptoms. Food intolerance tests are effective for identifying which foods are causing problems for people who have never had an allergic reaction before, as well as those whose reactions have not been consistent or severe. They may also be helpful for identifying potential allergens that someone has not previously been aware of


A food intolerance test is a diagnostic tool used to identify foods or ingredients that you may be intolerant to. Symptoms can include gas, bloating, abdominal pain and diarrhoea. Food intolerance is different from a food allergy. In food allergies, there is an immune system reaction to that particular food. Intolerance is the digestive system's response to food that the body is unable to digest fully.

Frequently Asked Questions

A food intolerance test is done to determine which foods an individual should avoid in order to prevent more serious health problems.

A food intolerance test is done to measure the following:

  1. Lactose intolerance: This test checks if the body can digest lactose, a sugar found in milk and dairy products.
  2. Fructose intolerance: This test assesses the body's ability to digest fructose, a sugar found in fruits and honey.
  3. Sucrose intolerance: This test checks if the body can digest sucrose which is found in sugar and many processed foods.
  4. Histamine intolerance: This test measures the levels of histamine in the body. Histamine is found in chocolate and fruits like pineapple, avocado and bananas.
  5. Gluten intolerance: This test checks for the presence of antibodies to gluten, a protein found in wheat, barley and rye. This test is done to check for celiac disease.
  6. Salicylates: This test checks the level of salicylates in the body. Salicylates are chemicals found in some fruits and vegetables as well as in some medications.

People with the following symptoms should do the food intolerance test:

  • Digestive symptoms: bloating, stomach pain, diarrhoea or constipation
  • Skin symptoms: itching, hives or eczema
  • Respiratory symptoms (asthma, sneezing, etc.)
  • Low energy levels
  • Unexplained weight gain or loss
  • Muscle ache

Mood changes: depression or anxiety

Food intolerance test measures the body's response to certain food ingredients. The test is typically used to diagnose food allergies or intolerances, but it can also be used to identify other causes of digestive problems. This can be useful in helping to determine the cause of symptoms, and may also help identify potential dietary remedies.

Some common food intolerance tests include the EGF (Elimination Glucose Food), IgG anti-sensitivity food sensitivity assay, and Oral Immunochromatographic Test for Fasting Blood Sugar).


Complete Process Involved

The doctor will ask you a series of questions about your symptoms, medical history and diet. You may also need to provide documentation from physicians or other healthcare providers who have treated conditions like asthma in the past year before we proceed with testing for food intolerance/sensitivities

In rare cases where things look serious then vomiting or diarrhoea may occur before testing begins so monitoring yourself is important!

Precautions to Be Taken

People who have food allergies are typically advised to avoid certain types of foods, and this includes those with food intolerances as well. But what precautions should people take when undergoing a food intolerance test?

Below are some tips: 

  • Eat light before your test. This means avoiding heavy meals and snacks beforehand so that your digestive system is in optimal condition for the evaluation.
  • Drink plenty of water while at the lab - both before starting the test and throughout it if necessary! Thirst can cause many false positives on food intolerance tests, so staying hydrated is key to ensuring an accurate result.
  • Before taking the test, make sure that you have ruled out all other potential causes of your symptoms (for example, medication side effects, and infections). 
  • Abstain from drinking alcohol for at least six hours before taking the test. This will reduce reaction times and improve accuracy overall.

The benefits of taking a food intolerance test can include discovering what you are allergic to or sensitive to. This can allow you to create a diet that meets your specific needs and is tailored to your body's requirements.

Some of the most common food intolerances include lactose intolerance, gluten sensitivity, and fructose malabsorption. These are all caused by an inability of your body to break down certain types of sugars or proteins.

If you have a food intolerance, it's important to know what steps to take next. After taking the food intolerance test, you will now have a better understanding of your symptoms and what triggers them.

  • First, it's important to track your diet. Make a list of all the foods that make you sick or cause discomfort. Then, try to avoid these foods as much as possible. If eating out is necessary for work or social events, be sure to ask about the restaurant's gluten-free policy in advance.
  • Next, it's important to identify any environmental factors that might be triggering your symptoms. This could include things like high levels of pollen or dust particles in the air, certain types of animals (especially cats and dogs), and chemical sensitivities at home or at work.
  • Finally, stay positive - with patience and consistency over time most people can overcome their food intolerance!

The following foods should be avoided if you have food intolerance:

Wheat products (including wheatgrass, wheat pasta, etc.) 

  • Gluten grains (wheat flour, durum flour, spelled flour, kamut®, barley malt), rye products (bread, bars), barley 
  • Legumes (beans/peas/lentils) 
  • Dairy products including milk, cheese, yoghurt 

By following the recommendations above, you can significantly reduce your risk of developing food intolerances in the first place!

If your food intolerance test comes out normal, eat whatever you want!
