Get reliable, actionable answers from your DNA!

Do you ever get an upset stomach, gas, diarrhea, or feel sleepy after eating? Do you suddenly have itchy eyes or difficulty breathing and suspect you might be sensitive to your new kitten’s dander? In your search for answers, the HomeDNA Food & Pet Sensitivity DNA test is a great place to start.

The personalized report from our DNA test tells you whether you are genetically more sensitive or less sensitive to specific irritants, giving you detailed information from your DNA about factors that may be causing discomfort from the inside out.

We make it easy from start to finish

You collect your own DNA samples quickly and easily at home using simple cheek swabs, send them back to us, and we do the rest. With this scientifically-based analysis, specific genes connected to the most common irritants are analyzed in our accredited lab. Results of your test are posted to your secure online account just 6 weeks after testing begins, so you get your answers fast!

Results include your genetic predisposition for sensitivity to:

  1. Gluten—Gluten is a protein in wheat, barley, and rye. Humans do not have the enzymes to break down gluten, leaving tiny particles in the digestive tract that may cause sensitivities for certain individuals
  2. Lactose—Lactose is a sugar found in animal-sourced milk and dairy products. Certain genetic markers may make it more likely to have difficulty digesting foods containing lactose
  3. Cow Milk Protein—Milk is made up of water, fat, lactose, minerals, and protein. Sensitivity to milk protein is not the same as lactose sensitivity, but it is one of the most common ones for children
  4. Egg—Egg sensitivities are very common, and many people are sensitive to the white part, called albumin, versus the yolk
  5. Peanut—Peanut sensitivity is extremely common and is often passed down through generations
  6. Other Foods—Many people are sensitive to other foods that are different from the ones included elsewhere in this test; they may include tree nuts, soy, corn, yeast, fish, and shellfish
  7. Pet Dander—Pet dander consists of tiny particles of skin shed from animals that have hair, fur, or feathers. Certain genetic markers may make an individual more sensitive to contact with dander
  8. Histamine—Histamine is a natural compound that may be found in foods that are aged and fermented, red wine, and more. Some people have an inability to break down excess histamine, which can cause sensitivities

In addition to giving conclusions about your sensitivity to individual irritants, the report also provides comprehensive and detailed diet, lifestyle, and supplement tips based on your results, so you can start making proactive changes right away.

Relief is in sight—you really can lead a more comfortable life.

The Science

The Science

Genetic testing has become more mainstream as current research highlights the results of our genes interacting with environmental factors. Many people believe genetic testing is becoming a tool for preventive health and wellness care. In addition to the thousands of tests being offered for medical conditions and diseases, the science and research behind genetic testing as it relates to the way our body responds to various irritants now enables consumers to investigate their genetic susceptibility to developing food or pet sensitivities.

The development of food sensitivities is not only common, but it’s growing—with 4-8% of children experiencing some type of food sensitivity. The most common foods that are potential irritants include: milk, egg, peanut, tree nuts, shellfish, fish, wheat and soy. Individuals with food allergies often experience a decrease in their quality of life and increased anxiety around food selection. Parents often feel a tremendous burden and worry when trying to monitor their child's food exposure if they suspect the child has sensitivities.

Food sensitivities are commonly inherited, which further supports the role of genetics in the development of these sensitivities. Research suggests that introducing potentially-troublesome foods to children at an early age may help sensitize them. Understanding a child’s or individual's genetic predisposition to food sensitivities may help parents make better strategic choices with their medical practitioner about when to introduce various foods. Additional research has found certain supplements or probiotics may help lessen the effect of various trouble foods.

With the advanced genetic testing technology and scientific understanding of the human genome available today, it is now possible to develop individually-tailored nutritional support and diet strategies to help you work with genes that may increase your development of food/pet sensitivities, specifically curated to your unique DNA. Only now has the cost of genetic testing come down to the point where it is feasible to use this technology. So go ahead—see what your genes have to say, and start enjoying a more comfortable life.

Analysis includes over 30 genetic markers (SNPs) that have been shown through external research to be related to sensitivity within each test category (for example, Gluten). The number of SNPs tested varies by category.
Typical turnaround time for getting results is 6 weeks, once samples arrive at the lab. We will email you as soon as your report is ready.

Your DNA is analyzed in eight (8) individual categories: gluten, lactose, cow milk protein, egg, peanut, other foods, pet dander, and histamine. In your report, results for each category where your genetics show a higher likelihood of sensitivity include the following sections:

Your Results—See details about your DNA data and a conclusion statement

Diet Tips—Get advice from professionals on how to improve your diet to lessen symptoms of sensitivity

Lifestyle Tips—Discover actionable changes you can make and steps you can take to relieve effects of sensitivity

Supplement Tips—Which supplements can be most helpful? We’ll tell you!

No. HomeDNA Food & Pet Sensitivity focuses solely on those genes that are related to the body’s sensitivity to the eight specifically-named irritants included in this test. Any DNA test performed to detect predictors for disease should be interpreted by a physician or a certified genetic counselor. Also, keep in mind this is not an allergy test. Confirmation of allergies should be issued by your medical provider.
This is a scientifically-based test. Please visit our Resources tab for links to studies used in the test report. Additionally, we have laboratory protocols that ensure very high accuracy, and so you can be sure your test has been processed correctly. Your genes play a big role in your body composition but it’s important to realize lifestyle and environmental factors may also play a significant role in sensitivities to irritants.

DNA is collected via a simple, painless cheek swabs. The inside of the cheek is rubbed for 30 seconds per swab in order to collect enough DNA to process the test. This is not a saliva test. 

Yes. For minor children, parental consent for testing is required via written signature on the swab envelopes.

No. New York and Maryland do not allow the retail sale or purchase of home DNA tests at this time. 

No. This test measures  your sensitivity to common irritants at the cellular (DNA) level. Since DNA stays constant from childhood through adulthood, there is no need to test again. 

Shrimp, apples, tree nuts, soy, soybean, fish, corn, and yeast are included in this category.

Gluten and dairy sensitivities have the most immediate physical effect on most people, so those whose DNA shows the possibility of sensitivities in these areas may want to start with those tips to see if it brings them relief. If symptoms remain, try eliminating foods from other categories, such as eggs and peanuts, then finally edibles from the "Other Foods" category. Of course, genetic indications of food or pet dander sensitivity are only one piece of the puzzle. Other factors, such as current diet, exercise, or other environmental conditions, may also affect sensitivity. Consult your medical practitioner before taking any supplements or making significant changes to your diet.

RESULTS INCONCLUSIVE  is displayed when the lab cannot detect the alleles (letters) that match with your gene or the gene is not found. This does not mean there is anything wrong with your genes or that there is something wrong with you.  Each time a new DNA sample is received, the lab creates a new analysis. Sometimes an analysis produces results that fall outside the area that the software expects. When this happens, the software cannot determine which letter combination (A, T, C, G)  is the correct result and issues the following symbol as a result:  (--) . RESULTS INCONCLUSIVE is displayed because the algorithm needs a letter combination to make a conclusion about your sensitivity. You may have (--) as a result for one of your genes and still have sensitivities to certain foods or pet dander. Rerunning your DNA cannot fix this issue, because the same thing will happen again.

Food & Pet Sensitivity DNA Test is rated 4.4 out of 5 by 53.
Rated 2 out of 5 by from I'm proud of the detailed report, that I like! In terms of customer service and the time it took to get those results... not so much. When I had bought the product from Walgreens, I would have expected at least somewhat the speed and efficiency of that from the retailer I bought it from. But after a month from purchasing it I gave the center a call, and they told me that I wouldn't get results until a month and a half after that. And on the date I should have got the results in, I didn't get them till a week after the turn in date. With spare calls in-between that have only met with the representative hanging up on me. Long story short, I got no problems with the report. In terms of rapid results, if you got 3 months to spare, have at it.

Rated 4 out of 5 by from Interesting results The HomeDNA Food & Pet Sensitivty test was very interesting to me. It’s something I’ve never seen anywhere else. Knowing what potential food or environmental allergies I have DNA markers for could potentially help in alleviating stomach/skin problems I have. I was shocked with the results. My kids do have allergies, so when my test showed that I had many genetic markers that are common in people with those allergies, was eye opening. I always assumed my kids got their allergies from my husbands side, but now I’m not so sure. I’ll definitely be doing more research on my family history with allergies, and seeing about cutting out specific foods, and seeing how I physically feel after a couple weeks. This was definitely a very informative and easy process.

Rated 5 out of 5 by from What a surprise I had with it! I teceived this test and at the beginning i was a little skeptical about it. I didn’t think it would work as well as a lab-present test, but I was wrong. I received my results 4 weeks after sending them and it was a very clear and complete presentation. Some results a was aware of but others were a complete surprise. I started thinking about them and finally realized I did have “weird reactions” (that is how I used to called them) with some of the items listed. What a great relief to finally knowing what is good and what is not so good for my body. It was a wonderful experience!

Rated 3 out of 5 by from Now I know I was able to send in my bucal swab to determine if I had a sensitivity to an array of different things such as grain, gluten, dairy and pet dander. It took roughly 7 weeks to get my results back which were nicely laid out on their online portal. It was need seeing my sensitivities with just only sending in an oral swab. I do think it is overpriced however seeing as the report did not ellude to what I was allergic to, simply sensitivities with no examples or exact source. I did like the ease of the online portal and sending my sample in but would have wished for more details.

Rated 4 out of 5 by from Lots of Sensitivities Found I have done other DNA programs before for other medical and ancestry traits. However, this DNA test showed possible sensitivities and allergy potentials. Some things I must say I don't fully agree with, but it was interesting to say the least. According to this test, the sensitivities include dogs, glutens, cows milk proteins, eggs, etc. Just about everything it says is a sensitivity. BUT... this could be completely true, family history of serious food allergies in a younger sibling, and Celiacs disease with the older sibling. Stuck in the middle makes you a sensitive person!

Rated 5 out of 5 by from Very easy It was very easy to register, easy to follow instructions in the kit, the prepaid mail in envelope was extremely convenient. The wait time for results I think was a very reasonable wait and once the results where ready they come in a very easy to read and follow explanation . For anyone wondering if its worth the money I say yes it is. My test was food and pet sensitivity dna test . They include diet ideas and ways to help. Great help to a healthier lifestyle.
