Abstract
A biosensor (12) includes a working electrode (5) and a counter electrode (3), wherein at least a part of the working electrode (5) is disposed between and in electrical connection with two separate conductive tracks (1,2). Other aspects of the invention provide a meter (26) for use with the biosensor (12) and a method of determining whether a fluid sample applied to the biosensor (12) has sufficiently wetted the working electrode (5).

13. A test meter for measuring analyte concentration in a biological fluid sample applied to a biosensor;
- the meter comprising;
a first electrical contact, a second electrical contact, and a third electrical contact, each for making an electrical connection with a corresponding contact pad on a biosensor;
means for measuring an electrical property between said first and second contacts;
means for applying a potential across the first electrical contact and the third electrical contact depending on whether the measured electrical property exceeds or does not exceed a first threshold value within a first pre-set time;
means for measuring an electric current value through said first and third contacts when said potential is applied;
means for converting said electric current value into an analyte concentration value; and
means for displaying said analyte concentration value. - View Dependent Claims (14, 15, 16, 17)
