In celiac disease, the immune system reacts to gluten exposure and attacks the tissues in the gut, causing inflammation and damage to the small intestine. At-home celiac tests will report on a range of antibodies or test for food sensitivities.

A person with celiac disease may be unable to absorb minerals and nutrients from food due to damage to the small intestine from repeat exposure to gluten.

The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) explains that the symptoms of celiac disease can be diverse and that a person may find they come and go. Symptoms can include bloating, chronic diarrhea, constipation, gas, and lactose intolerance.

According to a 2022 overview of medical issues associated with gluten, celiac disease mainly occurs in people with Northern European ancestry between the ages of 10–40 and recommends that people with these symptoms should get tested for the condition.

A person can use an at-home celiac test to check for antibodies associated with celiac disease. Genetic tests can also look for variations in a person’s DNA associated with celiac disease.

This article looks at 4 of the best at-home celiac tests a person can consider, discusses the symptoms of gluten sensitivity, and answers some of the most frequently asked questions about celiac tests.

Quick links

A celiac at-home test kit tests an individual, usually via a finger-prick test, to check if they have celiac disease.

A person can receive their results quickly with most test companies and can often access them remotely through online portals.

These tests can help a person understand what may be causing any digestive symptoms they are experiencing.

However, a person should always discuss their at-home celiac test results with a doctor, who will be able to give an accurate diagnosis and advice on the next steps.

Most at-home celiac tests are antibody tests. These tests check blood samples for antibodies associated with gluten sensitivity, such as:

  • Endomysial antibodies: (EMA) These antibodies consist of proteins that a person’s immune system produces. When the body perceives it is under attack, these antibodies cause intestinal swelling and prevent nutrient absorption into the blood. As such, people with celiac disease usually have high EMA levels.
  • Tissue transglutaminase (tTG): In celiac disease, tissue transglutaminase is an enzyme that can change the amino acid glutamine into glutamate. This change can cause certain cells to recognize glutamates in gliadin peptides present in gluten as foreign. In some people, this can cause a strong immune response, causing the symptoms of celiac disease. Celiac disease tests will look for tTG in the blood and, if present, will indicate that a person has celiac disease.

Other tests include genetic tests. These look for genetic markers associated with celiac disease. Those without the markers may not have celiac disease. Those with genetic markers are not guaranteed to develop celiac disease.

A person should always seek formal testing and diagnosis from a doctor to reach a correct conclusion.

MNT chooses at-home tests that meet the following criteria:

  • Laboratories: Where possible, MNT will choose companies that process test samples in CLIA-certified labs. This means they follow state and federal regulations.
  • Budget: MNT chooses at-home tests that suit a wide range of budgets.
  • Privacy: MNT includes companies that offer robust and transparent privacy measures, such as data protection and discreet packaging.
  • Test result speed: MNT selects companies that inform customers when they will receive their test results and whether they will receive them via email, app, or phone.
  • Further support: MNT will indicate whether a company offers further support, such as a follow-up phone consultation with a doctor to discuss test results.

Gluten sensitivity is a type of gluten intolerance, and a person with gluten sensitivity does not necessarily have celiac disease.


There are many gluten sensitivity symptoms, which can last hours or days. Some of the most common symptoms include:

A 2020 study noted that study participants with non-celiac gluten sensitivity reported brain fog, headaches, and tingling. However, the study did not include a diverse cohort, with most participants being female and 47 years of age.


There is currently no cure for celiac disease or gluten intolerance. Experts generally agree that a gluten-free diet is the best way to manage gluten sensitivity symptoms. Working with a doctor can help a person plan a balanced gluten-free diet.

Probiotics are also considered useful for a person with gluten sensitivity. They help increase good bacteria in the gut and help reduce symptoms of gas, bloating and constipation.

Currently, there are efforts to create a vaccine or gluten-degrading enzymes that a person can take to counteract their gluten sensitivity and enable them to eat gluten-based products again. However, this 2017 study has found that further studies are needed before either the vaccine or enzymes can be made available to the public.

Foods to avoid

If a person has a gluten sensitivity, they should avoid foods containing rye, wheat, barley, farina and other known gluten products.

Some examples of common household foods containing gluten include:

A person can eat the above foods if the label states “gluten-free,” meaning they have been made without gluten or have had the gluten removed.

Learn more about gluten-free diets.

A person should talk with a doctor if they are experiencing symptoms of gluten sensitivity, such as abdominal pain or bloating, and they last for 2 weeks or more.

If a person has taken an at-home celiac test, they should also consult a doctor about their results, particularly if they suggest celiac disease, food sensitivity, or intolerance.

Additionally, if a person is considering trying a gluten-free diet or changing their diet another way, getting advice from a doctor can ensure they can plan a balanced diet.

Below are answers to some of the most common frequently asked questions about at-home celiac tests.

Are at-home celiac tests accurate?

An older 2009 case report states that at-home celiac blood tests can be accurate. However, an intestinal biopsy is the only way to confirm if a person has celiac disease.

At-home tests cannot be considered 100% accurate or replace a diagnosis from a doctor.

What makes someone susceptible to celiac disease?

The precise cause of celiac disease is not known. However, some potential factors that may contribute to developing celiac disease are:

How does a person know if they are sensitive to gluten without a test?

The only way to know if a person is sensitive to gluten is by getting a diagnosis from a doctor. However, people can monitor their digestive symptoms when they eat foods containing gluten. Symptoms can include abdominal pain, flatulence, constipation, bloating, and brain fog. A person can use a food diary to monitor whether their symptoms improve by trying a gluten-free diet for a short time. A person’s symptoms can improve within a few days or weeks after removing gluten from their diet.

However, a person should consult a doctor before making extensive changes to their diet.

A person experiencing symptoms of celiac disease may wish to take an at-home celiac disease test. At-home celiac tests test for antibodies and enzymes associated with celiac disease.

A person can choose from a range of companies that provide simple celiac tests with fast results that can indicate whether a person is likely to have celiac disease or sensitivities to certain foods.

However, a person should consult a doctor to confirm a diagnosis of celiac disease and work with them to create a treatment plan.
