If you have taken an intolerance test with Allergy Test Australia, it may be that your test has not identified any allergies or intolerances, yet you are still experiencing symptoms. Don’t worry though, this is a good starting point and is one from which you can further explore the root cause of your symptoms.

Allergies and Sensitivities

If you are not shown to have any allergies or intolerances but are showing symptoms then it may be something completely different! We recommend you speak to a Doctor after taking our test, and this will further help you to understand your symptoms and results.

What are cross-reactions?

Well, a cross-reaction could be when you eat something which causes your symptoms and you are not aware of what is in it, causing a wide range of issues to your stomach. Some of the more common cross-reactions include Cheese, Mustard, Cacao and Coffee! Below are just some of the foods which may be influencing your results!


Coming from milk, cheese can cause a variety of symptoms which may be related to a food sensitivity. There are reactions to different cheese types which can occur due to the differing levels of proteins that are within the various products. Wow! Who knew you could get sick from cheese of all things?! If cheese is not highlighted but you think it may be an issue, then also check your casein levels!


Originating from the mustard plant, mustard is often found in jars and is often used by meat eaters to be smothered all over their sausages and burgers. What some people do not know, is that mustard can also be found in the form of mustard leaves, seeds, and flowers. Other things to watch out for in terms of mustard include Cauliflower, Cabbage, and Broccoli.


Everyone’s favourite, Coffee is derived from coffee beans. It is most commonly found as a drink, but it can also be used as a flavoring for cakes, ice cream, desserts, and even liquors. If you are looking for a substitute for Coffee, then look no further than Chicory and Barley. Remember, there may be other ingredients and not just coffee which may report an intolerance during your intolerance test.
