Abstract
An apparatus and method for determining the concentration of a medically significant component of a biological fluid comprise providing a cell supporting a chemistry which reacts with the medically significant component. Placement of first and second terminals of the cell in contact with first and second terminals, respectively, of an instrument permits the instrument to assess the reaction. The instrument determines a first response of the cell to a first signal, and determines based upon the first response whether to proceed with the determination of the concentration of the medically significant component of the biological fluid. If the determination is to proceed, the instrument determines the type of sample that has been applied. If the sample is a sample of a particular type, the instrument determines a first correction value based upon the cell's response to the third signal and combines the correction value with the result of the reaction assessment to produce an indication of the concentration of the medically significant component in the sample.
