Frequently Asked Questions

What is a Food Intolerance?


Food intolerances occur when you eat something but it fails to be properly broken down in the intestines. The main reason for this failure may be due to a lack of digestive enzymes among other factors.


What is the difference between a Food Intolerance and a Food Allergy?


The main difference between an intolerance and an allergy is that an allergy will manifest itself almost immediately after inhalation or consumption of a particular substance. Food intolerances, on the other hand, are more deceptive. Depending on the individual, symptoms may arrive anywhere between a couple of hours to a couple of days.


What are the most common symptoms of Food Intolerance?


Negative food intolerance related symptoms may include fatigue, migraines, eczema, bloating, gas, weight gain, brain fog, joint ache, acid reflux, food cravings, diarrhea, and more.


Is it possible to determine your intolerances by yourself?


No. Even with a thorough elimination diet it is possible to misdiagnose yourself with an incorrect food intolerance.


What is Pinnertest?


Pinnertest is a food intolerance testing company that uses advanced technology to analyze blood samples and identify an individual’s food intolerances.


What is the technology and science behind Pinnertest?


By analyzing IgG (FC Fragment Specific), Antigen, Antiserum, Control tests, our lab can thoroughly measure IgG antibody levels against the proteins of over 200 different foods. This progressive technique works to identify the foods that respond negatively with your system–all with just a few drops of blood dispensed by a basic finger prick.


Can I understand the results by myself?


Yes, the results are meant to be as easy to understand and user-friendly as possible.


How can I order a Pinnertest?


Ordering is easy! Fill out the information here, insert a promo code (if available), and we’ll get one to your door in no time with free express shipping.


Is Pinnertest covered by insurance?


Pinnertest is not currently covered by insurance.


Do you ship internationally and do you pay for shipping?


Yes we ship worldwide, free of charge both ways.


How long does it usually take to receive my kit?


It typically takes 3-4 business days to receive our kits.


Do you have a return policy?


A test may be returned and refunded if it has not been opened or used. Any tests that are administered and sent to our lab are nonrefundable.


How long does it take to receive my results?


After our lab receives your blood sample, it typically takes 7-10 business days to receive your results via email.

What do the results look like?

What do the “reaction degrees” on the results report mean?


The reaction degrees are an indicator of how sensitive (or reactive) your body is to a particular food. +1 is a low reaction. +2 is a moderate reaction. +3 is a high reaction.


Why is there just a few foods on the red side?


Having only a few items in the red column is very common. However, it’s important to be aware of all the different versions or products that particular food is found in. For instance, you may only have an intolerance to tomato but will then also have to avoid pasta sauces, pizza, ketchup, certain chips and other tomato products.


I know some foods that I eat make me sick but they don’t show up in my results; why?


One reason you might be surprised by your results is because the food that you are actually intolerant to causes inflammation in your digestive system. This is a natural response from the immune system to neutralize what it thinks are foreign intruders in the body. Then, while this inflammation attack is occurring, the other foods that you eat (the foods you think make you feel sick) can compound the inflammatory response even more, causing negative symptoms.


Do I have to repeat the test later?


It is not necessary to retake the test prior to 4 years.


I eat some of the foods I’m intolerant to all the time and feel fine; why?


The delayed reaction that is common in food intolerance make it hard to pinpoint exactly which foods are causing problems. In fact, sometimes food intolerance related symptoms don’t appear for up to 48 hours. So, for instance, you might eat something and feel fine, but then several hours (or days) later you might feel a negative reaction and attribute it to the wrong foods.


I am allergic to a food but it did not show up on the results; why?


Pinnertest analyzes your blood sample for intolerances only and not allergic reactions. An IgG antibody response, the kind of antibody the body releases when dealing with a food intolerance, is different than an IgE antibody response which pertains mainly to allergic reactions. Pinnertest does not test for IgE antibodies. In other words you can be allergic to a food, but, unless you’re also intolerant to it, it will not show up in your report.


I’m intolerant to a food that I’ve never eaten; why did it show up on my results?


While you may not think you’ve ever eaten a particular food, it is still possible that the protein found in that food was included into some processed good that you’ve previously consumed.


What changes should I make after I receive my results?


Eliminating the problem foods from your diet and replacing them with nutrient-dense alternatives is highly recommended to alleviate negative food intolerance related symptoms.


Do you suggest any fitness or nutrition plans?


While we do not prescribe any dietary plans or fitness regimens after taking our test, eliminating the intolerances from your diet paired with a healthy, balanced lifestyle yields the best results.


I am intolerant to gluten, but barley, oat, wheat and spelt are not on the red side? Why?


Because Pinnertest tests your reaction to individual food proteins, it is possible that your body is intolerant to the protein found in gluten while still testing negative for the protein found in barley, oat, wheat or spelt. Still, since these items contain gluten, it is recommended that you avoid them
