Abstract:
1. A test strip for measuring a concentration of an analyte of interest in a biological fluid, the test strip comprising: a substrate having a surface; a first measurement electrode formed on the surface; a second measurement electrode formed on the surface; a first latent electrode formed on the surface; a second latent electrode formed on the surface; a first contact pad formed on the surface and conductively coupled to the first measurement electrode; a second contact pad formed on the surface and conductively coupled to the second measurement electrode; a third contact pad formed on the surface and conductively coupled to the first latent electrode; a fourth contact pad formed on the surface and conductively coupled to the second latent electrode; and a conductive link formed when manufacturing the test strip, said conductive link coupling one of the first and second latent electrodes to the first measurement electrode, whereby the one of the first and second latent electrodes coupled to the first measurement electrode is not used as an electrode and the one of the first and second latent electrodes not coupled to the first measurement electrode becomes an active electrode.
