Abstract
A disposable test cartridge to determine the concentration of one or more liver enzymes in a blood sample includes a cartridge body having a plurality of chambers where at least one of the chambers contains a reactant mixture that reacts when catalyzed by one of the liver enzymes ALT, AST, ALP, or GGT in a blood sample forming a reaction solution, a removable cartridge cover connected to the cartridge body, and a test strip module connected to the cartridge body. The test strip module containing at least one analyte test strip configured for receiving a portion of the reaction solution and electrochemically measuring at least one analyte that is a reaction product in the reaction solution.
