Abstract

An article suitable for conducting one or more assays with an apparatus, e.g., a meter, for determining the presence or concentration of an analyte in a sample of biological fluid. The article contains a plurality of biosensors arranged in such a manner that each of the biosensors can be utilized before the article must be removed from the apparatus.

Claims

1. A method of determining the concentration of an analyte, comprising:

advancing a multiple test strip cartridge in an analyte testing device, wherein the multiple test strip cartridge comprises;

a plurality of test strips in the analyte testing device, wherein advancing the multiple test strip cartridge comprises positioning a first test strip of the plurality of test strips at sample application zone in the analyte testing device;

a plurality of segments arranged in a line, each segment having;

a first recess on one major surface thereof comprising the first test strip having an electrode arrangement;

at least a first slot for moving said segment linearly; and

a second recess for allowing a lancing device to pass therethrough;

positioning skin of a subject adjacent to the second recess;

lancing the skin by passing the lancing device through the second recess thereby depositing a sample of biological fluid at a sample receiving area of the first test strip;

electrolyzing the biological sample in the first test strip using the analyte testing device; and

displaying a determined concentration of an analyte in the biological sample on a display of the analyte testing device.

2. The method of claim 1, wherein each segment has at least a second slot for indexing said segment when a test strip supported by said segment has been used.

3. The method of claim 1, wherein said segments are separated from adjacent segments by perforations or score lines.

4. The method of claim 1, wherein said segments are detachably attached by rupturable links, whereby a given segment can be detached from an adjacent segment.

5. The method of claim 1, wherein said segments are detachably attached by links, each of said links comprising a pin and a pin holder, said pin capable of being removed from its respective pin holder.

6. The method of claim 1, wherein said segments are arranged in a fan-fold configuration, in which the segments resemble the folds of a fan or the pleated bellows of an accordion.

7. The method of claim 1, wherein said segments are arranged in a round track configuration which resembles a roll.

8. The method of claim 1, wherein said segments are arranged in an L-shaped configuration, in which the segments do not form a closed loop.

9. The method of claim 2, wherein the first slot is at a first end and the second slot is at a second end of each segment.

10. The method of claim 1, wherein the analyte is ketone or glucose.

11. The method of claim 1, wherein the method further comprises advancing the multiple test strip cartridge to position a second test strip at sample application zone in the analyte testing device.

12. The method of claim 1, wherein the second recess comprises an aperture.
