Abstract
The present invention provides a test strip for measuring a concentration of an analyte of interest in a biological fluid, wherein the test strip may be encoded with information that can be read by a test meter into which the test strip is inserted. In one embodiment, a first test strip comprises: a first measurement electrode connectable to a test meter; a first trace loop with a first associated resistance, where the first trace loop is connectable to the test meter; and a second trace loop with a second associated resistance, where the second trace loop is connectable to the test meter. The test meter is adapted to: receive the first test strip; connect to the first measurement electrode, the first trace loop, and the second trace loop; and obtain a first resistance ratio by comparing the first and second associated resistances.
