ASS intolerance testing
Allergies from the atopic group, such as hay fever, neurodermatitis, bronchial asthma and also nasal polyposis, can be associated with an analgesic intolerance - e.g. foods containing aspirin or salicylate. In this case, even if the prick test is negative, polyps may recur in the nose without any other allergy symptoms being present. To test this, a so-called ASA provocation should be carried out. Here, after a salicylate-free diet, aspirin in tablet form is given in increased doses. If there is itching, sneezing, eye tears or a bronchial reaction, one can assume a salicylate intolerance and make the immune system insensitive to these salicylates by taking aspirin regularly for about 1 year.
