Patent ID: 7968058

Claim:
A system for measuring a concentration of an analyte of interest in a biological fluid, comprising: a test meter; a first test strip with a first mask configuration, a first resistive element, and a second resistive element, said first mask configuration comprising: a first measurement electrode connectable to said test meter, a first trace loop with a first associated resistance and a first gap, said first trace loop connectable to said test meter, and a second trace loop with a second associated resistance and a second gap, said second trace loop connectable to said test meter; wherein said first resistive element is conductively connected to said first trace loop and bridges said first gap; and wherein said second resistive element is conductively connected to said second trace loop and bridges said second gap; a second test strip with a second mask configuration, a third resistive element, and a fourth resistive element, said second mask configuration being substantially similar to said first mask configuration, said second mask configuration comprising: a second measurement electrode connectable to said test meter, a third trace loop with a third associated resistance and a third gap, said third trace loop connectable to said test meter, and a fourth trace loop with a fourth associated resistance and a fourth gap, said fourth trace loop connectable to said test meter; wherein said third resistive element is conductively connected to said third trace loop and bridges said third gap; and wherein said fourth resistive element is conductively connected to said fourth trace loop and bridges said fourth gap; and wherein said test meter is adapted to: receive said first and second test strips, connect to said first and second measurement electrodes, connect to said first and second trace loops, obtain a first resistance ratio by comparing said first and second associated resistances, connect to said third and fourth trace loops, and obtain a second resistance ratio by comparing said third and fourth associated resistances.
