1. An integrated analyte lancing and testing strip for measuring a body analyte-level, comprising:
- a lancet needle; and
a test strip coupled to the lancet needle, the test strip and lancet needle on opposite ends of the integrated analyte lancing and testing strip, the test strip comprising;
a base;
a cover;
multiple electrodes including a working electrode applied to a first major surface of the cover;
a sample receiving portion of the test strip at an end opposite the lancet needle;
electrical contacts on a second major surface of the cover between the sample receiving portion of the test strip and the lancet needle;
a layer of electrically conductive material applied to a major surface of the base;
a sample flow channel including assay chemistry for testing an analyte level of an applied body fluid; and
at least one layer of electrically conductive adhesive for adhering the base to the cover, wherein at least one electrical passageway exists from the first major surface to the second major surface of the cover;
wherein the integrated analyte lancing and testing strip is configured to flip such that the test strip receives body fluid at the lancing site.
