The gold standard of allergodiagnostics lmmunoCAP for the quantification of specific IgE to foods that patients often complain about, but in fact they very rarely cause IgE-dependent allergy, and the mechanism of such allergy is stimulation of histamine production.
What could be behind the symptoms?
Histaminoliberators are substances that can cause the release of histamine from mast cells and basophils in the body. This can lead to symptoms that mimic an allergic reaction, that is, pseudoallergia. It is important to distinguish between pseudoallergies and true allergies because true allergies can be life-threatening, whereas pseudoallergies are not.
Among the most common foods that can cause pseudoallergic reactions are foods such as red berries, chocolate, coffee, tomatoes, citrus fruits and various types of seafood. However, a true allergy to these products is also possible, although very rare.
How is this package useful for doctors?
Of course, a positive result can help identify specific foods that cause an allergic reaction.
But a negative result, which is more probable in this case, is also informative. This can help reassure the patient or their parents that there is no real allergy and that the symptoms they are experiencing are probably caused by other factors. This can help reduce anxiety and fear and prevent unnecessary dietary restrictions.
