Abstract

A test strip including a reagent end for receiving a body fluid sample and an insertion end which is received at a test strip receptacle slot of a measuring device, the insertion end including one or more on-strip indicators for indicating to a measuring device that the test strip has been inserted into the device so that the device will power-up in preparation to perform a test, and the one or more on-strip indicators having a distinct pattern indicating whether calibration is automatic or whether the user needs to input calibration information to the said device, and corresponding methods are disclosed.

Claims

1. A test strip, comprising:

a reagent end for receiving a body fluid sample and an insertion end which is received at a test strip receptacle slot of a measuring device, the insertion end including one or more of a distinct contour, perimeter pattern, shape, thickness, width or other geometric, material or other measurable property, or combinations thereof, indicating whether calibration is automatic or whether the user needs to input calibration information to the said device.

2. The strip of a claim 1, wherein the user enters a calibration information corresponding to a package of strips.

3. The strip of claim 2, wherein the user enters a calibration code to the measuring device.

4. The strip of claim 1, wherein calibration is automatic.

5. The strip of claim 1, wherein the test strip is an electrochemical test strip.

6. The test strip is claim 5, comprising a working electrode and a reference electrode in a coplanar arrangement.

7. The strip of claim 5, comprising a working electrode and a reference electrode in opposing arrangements at the reagent end.

8. The strip of claim 1, wherein the strip comprises a top fill, side fill or corner fill configuration, or combinations thereof.

9. The strip of claim 1, wherein the reagent end comprises one or more of a rectangular or tapered shape, or a combination thereof.

10. The strip of claim 1, wherein the reagent end includes a sample fill area including one or more protrusions, cut-outs, notches, or indentations, or combinations thereof.

11. The strip of claim 1, wherein the strip is configured for amperometric or coulometric measurements, or both.

12. A test strip, comprising:

a reagent end for receiving a body fluid sample and an insertion end which is received at a test strip receptacle slot of the measuring device, the insertion end including one or more of a distinct contour, perimeter pattern, shape, thickness, width or other geometric, material or other measurable property, or combinations thereof, indicating a particular calibration requirement corresponding to a type of the test strip which contrasts with different calibration requirements of at least one other type of test strip.

13. A glucose meter device, comprising:

a test strip receptacle slot that is configured for receiving a glucose monitoring test strip which includes a reagent end for receiving a body fluid sample and an insertion end which is received at the test strip receptacle slot, the insertion end including one or more of a distinct contour, perimeter pattern, shape, thickness, width or other geometric, material or other measurable property, or combinations thereof, that is identifiable by the meter device indicating whether calibration is automatic or whether the user needs to input calibration information to the meter.

14. The meter of claim 13, wherein the user enters a calibration code corresponding to a package of strips.

15. The meter of claim 13, wherein the user inserts a predetermined test strip that includes a memory chip that has calibration information on it for transmitting to the meter.

16. The meter of claim 13, wherein calibration is automatic.

17. The meter of claim 13, comprising program code embodied within a processor-readable medium for identifying a type of test strip inserted at the test strip receptacle slot and proceeding with a glucose test procedure in accordance with a predetermined calibration requirement corresponding to that type of strip.

18. The meter of claim 13, wherein the test strip receptacle is configured to identify the insertion end of the test strip inserted at the test strip receptacle.

19. The meter of claim 13, wherein the test strip receptacle is configured to identify the test strip inserted at the test strip receptacle.

20. The meter of claim 13, wherein the strip is configured for amperometric or coulometric measurements, or both.

21. A glucose meter device, comprising:

a test strip receptacle slot that is configured for receiving a glucose monitoring test strip which includes a reagent end for receiving a body fluid sample and an insertion end which is received at the test strip receptacle slot, the insertion end including one or more of a distinct contour, perimeter pattern, shape, thickness, width or other geometric, material or other measurable property, or combinations thereof, that is identifiable by the meter device indicating a calibration requirement corresponding to a type of the test strip which contrasts with different calibration requirements of at least one other type of test strip.
