The present invention relates to a control solution for and a method of testing the performance of an electrochemical sensing device for determining the concentration of an analyte in a blood sample. The device contains a sensing means having a working electrode on which is deposited an enzyme capable of reacting with the analyte to provide electrons and a mediator to shuttle the electrons to the surface of the working electrode. The control solution is formulated so that the device will recognize the control solution as being something other than blood and automatically exclude the results obtained with the control solution from its memory unit. |
