Disposable test sensor with improved sampling entrance

A method of fluid sampling using a test sensor comprising the steps of:

• contacting a fluid opening of a test sensor to a fluid sample, the opening drawing a portion of the fluid sample into a fluid cavity by capillary action;
• connecting the sensor to a monitor or meter, the monitor or meter determining a property of the fluid;
• and
• wherein the test sensor comprises:
• a body comprising an electric contact end, and a sampling end, the electric contact end having electric contacts, the sampling end defining fluid chamber and having three wells within the fluid chamber;
• wherein the three wells are arranged to define an approximate triangle, the first well positioned at a vertex angle opposite to the triangle base which is defined by the second and third wells, the first well being farther from a front edge of the body sampling end than the second and third wells, the well arrangement providing accurate current so long as a fluid is contacting at least two of the three wells.

• wherein the test sensor comprises a base layer, a spacer layer, and an upper layer, the fluid chamber defined by the base layer, spacer layer, and upper layer, and wherein the fluid opening is formed along the front edge of the body providing fluid access to the fluid chamber;
• wherein a front sampling end of the spacer is recessed from a front edge of the upper layer sampling end and recessed from a front edge of the base layer sampling end, the spacer recession defining two side openings, one on a first side of the test sensor and another on a second opposite side of the test sensor;
• and
• wherein the contacting step comprises contacting at least one of the front edge, one, or both of the two side openings to the fluid sample, thereby providing a greater than 180 degree sampling entrance.
