Many aspects of the invention will be apparent from the following paragraphs and detailed description some of which are as follows. In one example, the invention includes a circuit for measuring an analyte or indicator in a body fluid sample including a reference voltage circuit, at least one measurement line, a result line, a buffering circuit between the voltage reference circuit and the measurement line wherein the buffering circuit comprises at least one operational amplifier the output of which is connected to the result line. The circuit may be a glucose concentration measurement circuit delivering the glucose concentration in a body fluid such as for example blood, plasma, interstitial fluid, urine. The circuit may further form part of a meter or system for measuring glucose concentration in a body fluid.
