Food & Pet Sensitivity Testing

What genes are included in the Food & Pet test?

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.

How long does it take to get my results?

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.

What information is included in my report?

Your DNA is analyzed in 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!

Do you test for any serious inherited diseases?

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.

How dependable are the results?

This is a scientifically-based test. See links below for 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.

Can minor children take this test?

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

Can this test be purchased in New York and/or Maryland?

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

Do I need to take this test more than once?

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. 

What types of foods are included in the “Other Foods” category?

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

My DNA shows that I am “more sensitive” across several categories. How do I know which recommendations to start with in order to feel better?

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.

My report shows “results inconclusive” in a category. What does this mean?

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.
