Best for a U.K. laboratory: Test My Allergy Combined Allergy & Intolerance test
- Sample method: This product requires a finger prick blood sample.
- Pro: The company uses an ISO-9001 certified lab.

The company sends all tests to an ISO-9001 certified laboratory for analysis. This means it must adhere to specific quality standards.
This particular test analyzes the presence of immunoglobulin E (IgE) and IgG4 against 70 of the most common allergy and purported intolerance items.
However, there is no medical or scientific data to suggest that IgG4 levels correlate with true intolerances or sensitivities. The American Academy of Allergy, Asthma, and Immunology (AAAAI) and other allergy societies worldwide warn against this type of testing, as it has never been scientifically validated.

When selecting at-home allergy test, a person might consider:
- Sample method: Most allergy tests require a blood sample. Anyone uncomfortable taking their own sample might ask a friend or family member for help.
- Allergies and intolerances: Anyone who thinks that they might have a specific allergy or intolerance should check that the test looks for this.
- Results time: Consider the time it will take for the company to return results. Some companies offer a quicker turnaround time than others.
- Budget: Generally, a test that screens for more allergies and intolerances costs more than a test that screens for fewer.
Currently, there is little evidence that at-home tests can accurately identify allergies or intolerances. Be sure to follow up any results with a healthcare professional.
The AAAAI states that allergies happen when a person’s immune system mistakenly believes that a substance is harmful.
When the body comes into contact with this substance, it produces antibodies, such as IgE, to protect itself. These antibodies travel to cells that release chemicals, including histamine, that when triggered cause an allergic reaction.
An allergic reaction commonly causes inflammation and irritation. In severe cases, exposure to an allergen can cause anaphylaxis, which can be life threatening.
Some common allergens include:
- dust mites
- insect stings
- animal dander
- medications or drugs
A person experiencing symptoms of a nonfood (environmental) allergy may benefit from taking an at-home allergy test. Common symptoms of nonfood allergies include:
- itching, hives, or rash
- itchy or sore throat after exposure to allergen
- sneezing or coughing
- itchy, watery, or red eyes
- wheezing or shortness of breath
It is important to note that the result of an at-home allergy test is not a diagnosis. After completing an at-home allergy test, a person should contact a doctor who can provide a diagnosis if necessary.
Health authorities, such as the AAAAI, do not recommend at-home tests. Anyone who may have an allergy or intolerance should speak with a doctor.
Food intolerances can cause symptoms such as gas, abdominal pain, or diarrhea. Common food intolerances include dairy and alcohol. Food allergies can cause a wide range of symptoms, including:
- itchy skin
A doctor may diagnose an allergy after conducting a skin test. This often involves pricking the skin with a needle or plastic prong that has a common allergen on it.
Many at-home allergy tests work by obtaining a blood sample using a finger prick. However, this method may not be a reliable way to determine whether or not a person has allergies.
At-home tests that look for IgG4 in the blood are unlikely to provide accurate results, as this antibody is present in people who do and do not have allergies to substances. IgG4 tests are commonly used for at-home food allergy and intolerance tests.
An individual who does decide to use an at-home allergy test will likely find it beneficial to follow up on their test results with a doctor.
Some allergy tests may return a false-positive or false-negative result. It is important to see a healthcare professional for additional explanation and testing, especially if an individual is testing for food allergies.
An at-home allergy test should not replace a visit to a primary care doctor or an allergist or immunologist.
These tests may not always be accurate, so a person should interpret their results with caution and seek follow-up tests with a healthcare professional. Alternatively, people may speak to their doctor instead of using an at-home allergy test.
The American College of Asthma, Allergy & Immunology recommends seeing a healthcare professional if:
- A person’s allergies cause chronic sinus infections, nasal congestion, or breathing difficulties.
- A person has true IgE-mediated food allergy symptoms, such as hives, swelling, vomiting, wheezing, or anaphylaxis
- A person experiences hay fever or other allergy symptoms for several months per year.
- Over-the-counter medications do not help or cause unpleasant side effects.
- Allergies interfere with a person’s day-to-day activities or decrease their quality of life.
- A person experiences warning signs of severe asthma, such as struggling to catch a breath, wheezing and coughing, frequent shortness of breath or chest tightness, or frequent asthma attacks.
When to get emergency medical advice
A person must seek immediate medical advice if they are experiencing anaphylaxis.
Below are answers to common questions about at-home allergy tests.
Can a person take an allergy test at home?
Several companies sell at-home allergy tests.
The packaging includes instructions about how to take a sample, usually a blood sample, and send it to the lab that the company uses. Within days, a person receives their test result.
However, it is important to note that health authorities such as the AAAI do not recommend at-home testing. A person should always follow up on their results with a healthcare professional.
Are at-home allergy tests accurate?
Most at-home allergy tests screen for the presence of IgG4. However, no research suggests that this is an accurate way of testing for allergies — IgG4 is present in people without allergies and intolerances.
Anyone who opts to take an at-home allergy test should follow up with a healthcare professional, who will perform further tests. They may then diagnose any issue and suggest an approach to treatment.
There are various at-home allergy tests that a person can purchase. These tend to test for various allergens, but some combine allergy tests with purported intolerance testing.
Many at-home allergy tests require a blood sample. Some products include equipment and instructions that allow the person to obtain the blood using a small finger prick. Some products, however, require a healthcare professional to take a person’s blood in a laboratory.
At-home allergy tests are not always reliable. People should not use these tests as an alternative to contacting a healthcare professional.
