Electrode layout for blood test sensor strip

A method for performing a plurality of blood sample acquisition and testing procedures on a strip

• having a plurality of test sites arranged in series in a travel direction on the strip, wherein each test site includes a lancet hole, first electrodes for producing a first signal when a sufficient volume of a blood sample is detected, second electrodes for obtaining a second signal characteristic of the blood sample, and a plurality of conductive pads that are aligned in a matrix of rows and columns and are aligned to make electrical contact with device contacts on a blood test sensor device, wherein the conductive pads for the first electrodes are electrically connected thereto by respective conductive traces, wherein the conductive pads for the second electrodes are electrically thereto by respective conductive traces, and wherein a leading edge in the travel direction of a first conductive pad in a row is in front of a leading edge in the travel direction of a second conductive pad in the same row, comprising the steps of:
• injecting a lancet through the lancet hole at a first test site into a subject to obtain the blood sample;
• contacting the blood sample with the first electrodes;
• advancing the strip in response to the first signal produced by the first electrodes;
• contacting the blood sample with the second electrodes to obtain the second signal;
• and
• advancing the strip to a second test site.
