A group of German researchers at the university medical center in Freiburg have created a new diagnostic tool, which is effective in determining the allergy to the venom of some insect bites, such as bees or wasps. The finding has been presented in the XXX Annual Congress of the European Academy of Allergy and Clinical Immunology (EAACI, for its acronym in English), held from 11 to 15 June in Istanbul (Turkey).

So far, in the tests that were used to determine the allergy to this type of poison, there was usually an undesired effect called double positivity, and related to cross reactions or CCDs. With this new test it is possible to eliminate this problem and, therefore, determine exactly what poison has produced or can produce the reaction.

The new test allows to determine exactly which poison has produced or can produce the reaction

The discovery has a lot of relevance because this type of reactions can be quite serious, and even cause the known as 'anaphylactic shock, that puts in serious danger the life of the subject. This tool can discriminate between real and "false" reactions and, therefore, help allergists know if the cause is the bee or wasp's poison.

In this way, once the causer is determined, the reaction could be prevented. In this sense, several studies have determined that the optimal treatment of poison allergy is the immunotherapy of the poison.
