Comparison study of three rapid test kits for histamine in fish: BiooScientific MaxSignal enzymatic assay, Neogen Veratox ELISA, and the Neogen Reveal Histamine Screening test

► Enzymatic MaxSignal has fewer steps than Veratox ELISA. ► Enzymatic MaxSignal correlated with Veratox ELISA. ► Apparent inhibitors of enzyme used in MaxSignal require longer reaction time. ► Enzymatic MaxSignal has linear response to histamine in contrast to ELISA tests. ► Reveal, MaxSignal are promising rapid tests and compare well with Veratox.
