The kit format is a microtitre plate based assay that can be performed manually or on an automated ELISA system to reduce hands-on time.

CE marked protocols are available for the Dynex DS2 and DSx plus the Grifols Triturus®. Alpha Laboratories Ltd. supplies the Dynex DS2 for capital purchase or reagent rental.

Two different protocols are available with the fCAL ELISA to cover the ranges required for IBD and IBS differentiation plus the extended range format for use in monitoring patient therapy and mucosal healing. This reduces the need for further dilution and repeated assay.
