Critically appraised topic on adverse food reactions of companion animals (4): can we diagnose adverse food reactions in dogs and cats with in vivo or in vitro tests?

Table 2 Accuracy, positive and negative predictability^a of various tests in privately owned dogs with naturally occurring adverse food reactions based on provocation with individual food allergens

	Accuracy	Positive predictability	Negative predictability
Intradermal testing with food antigens [4, 14]	63–76%	60–67%	62–77%
Serum testing for food-specific IgE [4, 5, 14]	58–87%	15–100%	61–86%
Serum testing for food-specific IgG [5]	77%	35%	84%
Lymphocyte proliferation tests [14]	94%	100%	93%
Patch testing with food antigens [5, 25]	81–90%	63–75%	88–99%

^a The accuracy was calculated by dividing the number of correct results by the number of all results verified, positive predictability by dividing correctly positive results by the total number of positive results and negative predictability by dividing correctly negative results by the total number of negative results
