摘要： Methods and devices for electrochemically detecting a change in the viscosity of a fluid are provided. In the subject methods, a fluid sample (e.g., a whole blood sample) is introduced into an electrochemical test strip's electrochemical cell using a micro-needle integrated into one of oppositely spaced apart working and reference electrodes. An electric potential is applied to the electrochemical cell to first achieve a steady state cell current. A decrease in the steady state cell current is then detected and related to a change in viscosity of the sample. In many embodiments, the sample is blood and the change in viscosity is related to the onset of coagulation in the blood sample, and often the PT of the blood sample. An electrochemical test strip includes an electrochemical cell and an integrated micro-needle. The electrochemical cell includes oppositely spaced apart working and reference electrodes and a reagent mixture (e.g., a redox couple and a coagulation catalyzing agent). The micro-needle is integrated into one of the working and reference electrodes of the electrochemical cell.

摘要： A method for determining an analyte in a bodily fluid sample includes inserting the analyte test strip into a test meter. The insertion is such that an electrical connector pin of the test meter travels along an electrical contact pad of the analyte test strip, and across a meter identification feature disposed on the electrical contact pad, during the insertion. Moreover, during the insertion, a signal processing module of the test meter measures an electrical characteristic via the electrical connector pin as the electrical connector pin travels along the electrical contact pad and across the meter identification feature. The method also includes identifying the analyte test strip, using the signal processing module, based on the electrical characteristic measured as the analyte test strip is inserted into the test meter and, thereafter, applying the bodily fluid sample to the analyte test strip upon notification by the test meter that the identification indicates that such applying is appropriate. The method then includes determining an analyte in the bodily fluid sample using the test meter only if the identification indicates that such determining is appropriate. The electrical contact pad of the analyte test strip employed in the method has a predetermined contact electrical characteristic value and the meter identification feature of the analyte test strip has a predetermined identification feature electrical characteristic value that is dissimilar from the predetermined contact electrical characteristic, thus providing for identification of the analyte test strip by the test meter.
