Frequently Asked Questions


NutriScan, the novel patented salivary-based food sensitivity and intolerance test offers a reliable and clinically predictive alternative to food elimination trials, serum-based food allergy testing, and skin patch testing. Two completed, double-blinded clinical trial studies validated the test and affirmed its clinical utility.

Nutriscan is the only clinically predictable diagnostic test for dogs, cats and horses to identify the commonly seen food intolerances and sensitivities in saliva. It is not a test for the rarely seen true allergies to foods. The Nutriscan test is patent protected in the United States and internationally.

This test measures antibodies to certain foods in dog saliva. High antibody levels indicate that the dog has a food sensitivity and intolerance to that food or foods. It is not a DNA test or a cheek/gum swab test.

By contrast, cheek or gum swabs alone do not generate sufficient biological fluid to quantitatively determine specific food reactivities. Simple positive or negative results, for instance from tissue swabs, do not provide information about the specificity or sensitivity of the assays used. Therefore, selection of foods based upon this type of information is medically and scientifically unreliable.

No, NutriScan tests for food sensitivities and intolerances which are common, and not for true food allergies which are rare.

Yes, Nutriscan is unique, and quite different than serum-based tests for food reactions, food elimination trials, or skin patch testing with foods.

Skin testing used to be considered the gold standard of allergy testing. Aside from being unsightly and requiring that a large patch of skin be shaved, these tests are costly and do not always identify the true source of allergic reactions.

Saliva testing can reveal the latent or pre-clinical form of food sensitivity, as antibodies to food ingredients appear in saliva before the clinical or bowel biopsy diagnosis of inflammatory bowel disease or leaky gut syndrome is made.

This test was expanded in early 2012 to include two different panels each having 12 food antigens, for a total of 24 foods. There is Panel #1 = beef, chicken, corn, duck, lamb, cow’’ milk, pork, soy, turkey, venison, wheat, and white fish. The second panel = barley, hen’s egg, lentil, millet, oatmeal, peanuts, potato, quinoa, rabbit, rice, salmon and sweet potato. [Horses have a completely different set of 24 foods being tested.]

Food sensitivities are usually seen from as early as 2 hrs and up to 72 hrs after eating, so it can be difficult to connect symptoms with a food or foods eaten several days previously. There is a very high correlation between delayed food sensitivity and the amount and frequency of the food consumed.

Yes, because saliva testing can reveal the latent or pre-clinical form of food sensitivity, it can be used to predict a developing or latent food reaction.

Food allergy tests measure antibodies to IgG and IgE in serum or feces. These are typically more acute allergic reactions to foods, whereas NutriScan measures IgA and IgM antibodies on the bowel mucosal surface, and thus more directly correlates to symptoms of bowel (GI tract) disease.

You can order online via our order page.

No, this test can be ordered on our order page and shipped to your home.

Our canine and feline kit are $298.00 and the equine kit is $380.00 

We will send you instructions and a kit with a special cotton rope to collect your pet’s saliva. You should receive it within a few days after placing your order. Your pet will need to fast overnight before testing; water is okay.

Review the saliva sample tips.

You will also have the option to pay for a NutriGold consultation which will review NutriScan results in detail.

Yes, we recommend fasting after dinner and collecting the saliva first thing in the morning before breakfast.

Results will be emailed to you. Please allow approximately 2-3 weeks for the results. 

For International Samples – including Canada and Mexico – US Customs clearance requires a letter specifying that the “sample is from a horse, dog or cat for diagnostic purposes only, and is non-infectious.” Please click here for full instructions. Download the French, German, Italian and Spanish instruction sheet. 

Depending on your policy, most pet insurance companies cover not only routine checkups, but also emergency care, prescriptions, treatment and diagnostic testing such as NutriScan. Please check with your insurance provider or seek out health insurance for your companion pet. 

Please send back the sample within 10 days of collection. You can send the samples via FedEx, UPS or USPS Priority Mail. Return mailing to Hemopet needs to be in a protected package or envelope. No refrigeration is necessary, and the saliva sample is viable for up to 30 days; however we do recommend that the sample should arrive at Hemopet within 10 days of being taken. 

Yes, we do work with veterinarians. Please visit the Veterinarian Order page.
