lactose intolerance test at home

Many people are beginning to understand how particular meals might leave them feeling lethargic, upset their digestion, or even result in skin conditions like eczema. An at-home test might be the best choice for a quick lactose intolerant test at home or you if you suspect you could be sensitive to certain foods.

Unfortunately, not all tests for food sensitivity are equal. Some at-home tests call for a cheek swab, while others call for a finger prick. The methods used to interpret the findings also differ substantially.  

Although some test results concentrate exclusively on a few dietary groups, others offer many findings. If you’re looking for ways how to tell if you’re lactose intolerant, in this article, we have included the top lactose intolerance test at home alternatives and the many types of food intolerances tested to assist you in finding the best at-home food sensitivity test.

Lactose Intolerance Test At Home 

Dairy allergy vs. lactose intolerance is two different things. The lactase enzyme found in the intestines, which disintegrates lactose during digestion, allows the human body to metabolize milk and other dairy products. 

However, lactase levels might be abnormally low in some persons. For them, lactose will continue to build up and ferment in the intestines. Lactose intolerance is the term used to describe this inability to digest lactose.

So, how can you test for lactose intolerance? An evaluation of your body’s capacity to process lactose, a form of sugar in dairy products, is known as a lactose tolerance test. It can be done by a physician or through self-administration. Let’s look at five kits for lactose, food, or milk allergy test at home below:

  • Before undertaking this test, a minimum of four weeks should pass after a recent barium enema or colonoscopy.
  • The lactose intolerance breath test should not be used if you have recently taken oral antibiotics under the broad-spectrum category or bismuth products like Pepto Bismol.
  • Also, 24hrs before the test, avoid a certain list of foods for lactose intolerance. These include beans, fruits, fiber-rich foods, etc. You could opt for fish, eggs, chicken, white potatoes, white rice, vegetables (well-cooked), regular pasta, white bread, dairy, etc. 

Understanding Your Results

Positive Lactose Intolerance Test

Positive test results would appear as follows: 

  1. Lactose intolerance is indicated by a hydrogen breath test outcome that reveals an increase in the hydrogen of over 12 parts per million from your initial fasting test.
  2. If you have a blood glucose test and lactose consumption didn’t cause a rise in blood glucose concentrations. Your inability to digest lactose is most likely the cause of this.

Negative Lactose Intolerance Test

A negative test would be indicated by: 

  • If you underwent a blood test for glucose and your levels rose. This suggests that lactose intolerance is unlikely to be to blame for your issues. To identify the source of your symptoms, you might require more testing.
  • After consuming lactose, there is negligible hydrogen rise. This suggests that lactose intolerance is likely not to blame for your symptoms. To identify the source of your symptoms, you might require more testing.

What to Do If You Have Lactose Intolerance Symptoms FAQs

Are There Any Other Lactose Intolerance Self-tests?

A “provocation test” can be performed at home. In essence, this is the controlled consumption of lactose to induce the onset of symptoms.

It’s crucial that this type of screening not be performed if you’re currently aware of your lactose intolerance or know you react poorly to milk consumption. And you shouldn’t perform the self-test if you’re hypersensitive to milk or any products that include milk. 

How Is the Home Provocation Test Conducted?

Taking the test first thing in the morning and without food is preferable. 250ml of milk should be consumed quickly. Then, wait between 30 and 60 minutes while checking for signs like diarrhea, bloating, or abdominal pain. You might be lactose intolerant if you notice these symptoms.

You can perform a “blind” test with lactose-free milk as an extra measure of protection. That implies that you also have 250ml of lactose-free milk on hand and then consume either of the glasses without knowing whether it includes lactose-free milk. Clearly label the glasses in advance so you can subsequently identify the milk you used. Then carry on as normal while noting any symptoms that develop.

Verify the type of milk you consumed after completing the test. If you’re lactose intolerant, the milk containing lactose should worsen your symptoms, but lactose-free milk shouldn’t.

How Reliable Are Internet-based Lactose Intolerance Tests?

Online tests from many different suppliers guarantee quick and accurate assessment. These are typically pricey test kits utilized at home before being forwarded to a lab.

These tests can confirm lactose intolerance, but they don’t substitute diagnostic procedures. The testing can only contribute to our knowledge of the disease’s existence. This frequently signifies that the method is expensive but adds no value for the patient.


Having migraines, rash on your skin, irritation, or tummy discomfort, particularly after meals with milk, are all potential signs of lactose sensitivity. 

Speaking with a healthcare provider if you have these symptoms is best. However, a self-administered lactose intolerance test can help you better understand your dietary tolerance and set you on the road to improved nutrition and well-being and incorporating other products, such as greek yogurt for lactose intolerant

An at-home food sensitivity test can be a simple approach to diagnose the issue and enable you to begin a dietary elimination program that allows you to skip foodstuffs or irritants that could be the reason for your symptoms. These quick tests identify the foods triggering your symptoms by utilizing a little sample from your hair, blood, or saliva.
