Abstract

An apparatus (31, 32, 132) and method for determining the concentration of a medically significant component (for example, glucose) of a biological fluid (for example, blood) comprise providing a cell (31) for receiving a sample of the fluid (for example, blood). The cell (31) supports a chemistry which reacts with the medically significant component (for example, glucose), and first and second terminals gross which the reaction of the chemistry with the medically significant component can be assessed. An instrument (32, 132) has first (34-2, 134-2) and second (34-3, 134-3) terminals complementary to the first and second terminals, respectively, of the cell (31). An assessment controller (52, 54, 148, 158) is provided.
The apparatus determines the type of sample and the concentration of a medically significant component of the sample.
