What is a Food Intolerance Test?

A diagnostic method for detecting probable food sensitivities or intolerances in people is called the This test seeks to identify specific foods or dietary ingredients that cause unfavorable bodily responses. Food intolerances are defined by difficulty digesting particular meals or responses to specific food components, in contrast to food allergies, which include an immunological response.

The test usually involves examining a sample of saliva, hair, or blood to check the presence of immunological markers, antibodies, or other signs of food intolerance. Alternatively, certain tests may depend on testing specific chemicals, such as histamine or lactose, to determine tolerance levels. After the sample has been taken, it is transported to a lab for analysis. The results are then sent to the patient or their healthcare practitioner.

Food intolerance tests examine a wide range of potential triggers, including common allergenic foods like milk, eggs, wheat, nuts and other components such as gluten, lactose, or food additives. Some tests may target a specific food group, while others offer comprehensive panels that assess multiple foods simultaneously.

A food intolerance test's main goal is to assist people in identifying foods or components that contribute to adverse reactions in their bodies. People may make educated food decisions and reduce or control their symptoms by identifying these triggers. This might involve an elimination diet, in which probable trigger items are momentarily excluded from the diet, followed by a reintroduction phase to verify the responses.

However, it's important to note that food intolerance tests have limitations. Some tests' scientific validity and reliability have been questioned, as their accuracy can vary, and false positives or negatives may occur. Therefore, it is crucial to interpret the results with caution and in conjunction with clinical evaluation and guidance from a healthcare professional.

How does it work?

When using a Food Intolerance Test template, the following steps are typically involved:


To acquire appropriate data, address the patient's symptoms, medical background, and eating habits.

Test Selection

Choose the right food intolerance test based on the patient's unique requirements and potential trigger foods or components.

Sample Collection

Give the patient specific instructions for obtaining the sample, such as the needed sample type (blood, hair, or saliva). 

Laboratory Submission

Help the patient correctly package the sample and submit it to the specified lab while ensuring all transportation regulations are followed.


Tell the patient what to expect in terms of how long it will take to get the test results, which might vary based on the lab and the particular test.


When the findings are made readily available, carefully examine and interpret them while considering the particular foods or ingredients that contribute to increased levels of reactivity.

Patient Education

Make an appointment for a follow-up visit to go through the results with the patient, explain the relevance of the results, and offer advice on dietary changes.

Elimination Diet

Recommend an elimination diet where probable trigger foods are temporarily eliminated from the patient's diet based on the test results.

Reintroduction Phase

Following a period of elimination, assist the patient with reintroducing the foods one at a time while keeping an eye out for any adverse reactions or symptoms.

Follow-up and Monitoring

Keep in touch with the patient frequently to monitor their progress, discuss any problems, and alter their diet as necessary.

Scoring guide

To quantify the reaction shown in the test findings, each food item or component is given a value as part of the Food Intolerance Test Score. The values may be categorized as mild, moderate, severe, or numerical on a scale from 0 to 4. For this template, this is the interpretation of the results:

Elevated values >30 IU/mL

  • This indicates a strong antibody reaction
  • Stop intake of these foods immediately for at least 3 months
  • Choose alternate foods from the same group
  • Consult your physician

Borderline values 24-30 IU/mL

  • This indicates mild to moderate antibody reaction
  • Reduce the intake of these foods for at least 3 months
  • Choose alternate foods from the same group

Normal values <24 IU/mL

  • This indicates no significant antibody reaction
  • No dietary restriction if there is no previous history of reaction
  • If symptomatic, consult your physician even though the test is negative

Healthcare experts examine the test results and evaluate the amount of reactivity for each item to grade the evaluation. The values or grades given reflect the degree of the reaction. For instance, a grade of "non-reactive" or several 0 may imply no or little reactivity, whereas higher values or grades signify higher degrees of reactivity.

Using the Food Intolerance Test Score, medical practitioners may rank trigger foods or ingredients according to their respective values. This knowledge aids in directing dietary adjustments, such as removing or lowering highly reactive meals, while considering the possibility of including foods with lower reactivity levels.

When would you use this test?

Healthcare professionals can benefit greatly from the Food Intolerance Assessment test when addressing suspected food intolerances and conducting investigations. Here are some situations when the exam could be suitable and helpful:

Unexplained Digestive Issues

A food intolerance assessment can assist in pinpointing trigger foods that may be the source of a patient's discomfort when they arrive with unexplained digestive symptoms such as bloating, stomach pain, diarrhea, or constipation.

Skin Conditions

There may be a connection between some skin conditions like eczema, hives, or rashes and dietary intolerances. The examination can identify potential food triggers, enabling medical professionals to suggest suitable dietary changes.

Chronic Fatigue or Low Energy

Food intolerances may be a factor in the symptoms of people with chronic fatigue or low energy. The examination can reveal which foods contribute to varying energy levels, assisting practitioners in creating more precise dietary recommendations.

Inflammatory Conditions

Food sensitivities can make inflammatory diseases like arthritis, asthma, or chronic sinusitis worse. Through the examination, practitioners can possibly reduce inflammation and related symptoms by identifying and removing trigger foods.

Irritable Bowel Syndrome (IBS)

Food intolerances and IBS are frequently related. The evaluation can assist in identifying particular food triggers that may be exacerbating IBS symptoms, allowing practitioners to modify dietary advice accordingly.

Chronic Migraines or Headaches

Food intolerances have been associated with chronic migraines or headaches. Conducting the assessment can help identify potential trigger foods, allowing practitioners to explore dietary modifications as part of a comprehensive treatment plan.

Personalized Nutrition

The Food Intolerance Assessment can help create individualized nutrition programs based on unique sensitivities, enabling healthcare professionals to provide patients with tailored dietary recommendations to support their overall health and well-being.
