Abstract
In vitro electrochemical sensor that provide accurate and repeatable analysis of a sample of biological fluid are provided. In some embodiments, the sensors have a measurement zone that has a volume less than the volume of the sample chamber. The measurement zone could have a volume of no more than about 0.2 μL.
Claims20
A method of determining the concentration of an analyte in a sample in biological fluid, the method comprising:
- contacting a sample of biological fluid with a sample chamber of an analyte sensor, the sample chamber having a volume;
- filling only a portion of the sample chamber with the sample;
- monitoring a change in an existing signal from an indicator electrode present in the sample chamber;
- determining that the existing signal has not changed during a pre-determined time period;
- and
- determining the analyte concentration in the sample.
