A team led by PhD candidate Thimo Ruethers from JCU's Australian Institute for Tropical Health and Medicine (AITHM) evaluated 26 commercially available fish preparations used for skin prick testing, the most common way of diagnosing fish allergy in Australia.
"We found the amount of allergens present varied greatly, and in some preparations major fish allergens could not be detected. This means many skin prick tests that show a person being tested is not allergic to fish may be wrong," said Mr Ruethers.

Professor Andreas Lopata from AITHM said the diagnosis of food allergy is fraught with problems.
"There are no regulations requiring the standardisation of commercial preparations for skin prick testing, while improved preparations are pricey and often impossible to get," he said.
Mr - Ruethers - Results - Prick - Need
Mr Ruethers said results from skin prick testing need to be questioned as the current preparations appear unreliable in diagnosing fish allergy.
"We urgently need reliable tools to diagnose fish allergy, a serious and often life-threatening immune disease. Current tests can be falsely negative, putting lives at risk," he said.
