Difference between classic IgE food allergies and delayed IgG food allergies
There are various reasons why a food can cause problems, among them a classic IgE food allergy (type I) and a delayed IgG food allergy (type III), the latter is also referred to as food intolerance. What both allergies have in common is that the immune system is involved. However, there are some differences in the way it responses.
Classic IgE food allergy
A classic type I allergy is when the immune system produces specific IgE antibodies (immune globulins of the subclass E). These antibodies lead to an immediate allergic reaction. The symptoms appear within seconds or minutes: severe swelling, breathing difficulty, rash, itching skin or even anaphylactic shock.
Someone who has a type I allergy will most probably know which food is causing problems, because the symptoms appear right away. Therefore, blood testing is not necessarily needed to identify this kind of allergy. IgE tests are mainly performed for confirmation. ImuPro does not detect type I food allergies.
Delayed IgG food allergy
A type III food allergy is when the immune system produces specific IgG antibodies (immune globulins of the subclass G). These antibodies can lead to inflammatory processes. The symptoms appear up to three days after the consumption of a trigger food. Learn more.
It is very difficult to pinpoint which food causes you problems because of the delayed appearance. An IgG test helps to localise and limit the suspects.
With ImuPro you will only have to avoid foods with elevated IgG antibody values. This means that you can maintain a diverse and varied diet and don’t need to restrict yourself unnecessarily. You might need to avoid salmon, for instance, but be able to eat all other fish. After a certain period of avoidance, you may reintroduce one food after the other into your diet and monitor your symptoms. This provocation phase is the crucial step to identify your personal “trigger foods”.

How to interpret a positive Candida reaction in an ImuPro test?
First of all, a positive ImuPro test result for Candida does not mean that you have a Candida albicans infection and it should not lead to immediate treatment!
The ImuPro test detects IgG antibodies to Candida albicans. As shown above, IgGs are persistent antibodies which stay present in human serum for several months or years. This means that a positive reaction to Candida does not reflect an acute or present infection. It rather shows that the immune system had to fight Candida albicans in the past or present.
What to do next?
Please consult your physician! Normally a clinical investigation is done to see if any obvious infection on the skin (nails), in the oral cavity or on the sexual organs can be identified. If such an infection is localized, an appropriate treatment is put into place.
If no such infection could be localised, we suggest performing a stool test, in order to evaluate the gut burden of Candida albicans. If again no Candida albicans was detected, no further action is needed. The detected IgG to Candida albicans most probably reflects an old infection which has either been treated or which was resolved by the body’s immune system.
If a high amount of Candida albicans has been detected, a possible impairment of the gut’s barrier and permeability cannot be ruled out. In order to help the gut to recover, we suggest to treat the Candida infection, to restore the normal gut flora and to change your life style accordingly.
When can a food intolerance test be useful?
Many chronic diseases originate from a process called chronic inflammation. If you suffer from any of the following conditions, you might benefit from a food intolerance test to see, which foods suit you, and which can potentially cause inflammation:
|Autism||Diabetes type 2|
|Irritable Bowel Syndrome||Persistent Diarrhoea|
|Chronic Indigestion||Crohn’s disease|
|Weight Problems||Headaches and Migraines|
|Rheumatic Diseases||Lack of Concentration|
How does the test work?
The test involves taking a non-fasting blood sample which is analysed in a specialised laboratory in Germany with the ELISA method. The turnaround time is approximately 14 working days. You will receive the results via email.
We offer the ImuPro 300, which is using the ELISA (Enzyme-Linked Immunosorbent Assay) method. This is a well-established procedure in laboratory analysis. It covers 270 foods and additives and a recipe book to support your diet changes. The results are reliable, fully reproducible and are checked through regular quality controls.
Important Information: Please note that the test does not provide reliable results if you currently take steroids or certain other medication. You should not stop medication without consulting with your doctor! This test is also not an “allergy test”. You might have an allergy to certain foods but no intolerance, and vice versa.
You will receive detailed results via email containing:
- A brief report providing your level of intolerances to each trigger food at a glance with a handy “purse card”
- An extensive patient manual that includes a food encyclopaedia and provides you with background information and many hints and tips for a successful change in your diet
- A customised recipe book (subject to the number of positively tested foods) with a large number of tasty dishes to help you avoid problems with foods without scarifying the enjoyment and variety in your diet. Currently, this is unavailable from any other IgG food intolerance test provider! *)
Be aware that there are “cheap” food intolerance tests on the market. Unfortunately they are often not reliable, and not a good investment. You want to have a test that has been tried, tested and proven for many years.
*) Should you react to a very high number of food items, it might not be possible to provide a recipe book.
