How can you recognize a reputable blood test for intolerances?

The market for intolerance and allergy tests is confusing today— not every method advertised online as a “test” is scientifically recognized. A first quality criterion: A reputable test is based on a genuine blood sample and measures specific antibodies (IgG or IgE), rather than methods such as bioresonance, hair analysis, or applied kinesiology muscle tests, for which there is no scientific evidence base.

Second criterion: laboratory quality. The analysis should be carried out by an ISO-certified laboratory that delivers reproducible results. Third, the report should be easy to understand—with specific values for each food or allergen and an understandable explanation, rather than using blanket traffic-light symbols without context. And fourth, it should a reputable provider should communicate transparently that the test provides guidance and does not replace a medical diagnosis—without sensational healing promises or fearmongering.

IgG vs. IgE: What is the difference?

An allergy is an immediate, exaggerated reaction of your immune system to substances that are actually harmless. In doing so, your body produces specific IgE antibodies that activate mast cells when they come into contact with the allergen activate and release histamine, which causes typical symptoms such as itching, sneezing, or skin rashes. Medical professionals refer to this as a type I immediate reaction.

A food intolerance works differently: Here, the main factors are usually IgG antibodies, digestive enzymes, or the intestinal barrier may play a role, and the The reaction is often delayed—sometimes not until hours after eating. This makes intolerances harder to identify than classic allergies, because the symptom and trigger cannot be clearly can be attributed. That is precisely why an IgG blood test is so helpful here: It makes patterns visible that remain hidden in everyday life.
