Enclosed Test Strips

At least two meters use cartridges that contain several test strips. The cartridges are stored within the meter, so that the patient does not have to carry around separate strips, which may be dropped or accidentally wetted prior to insertion. Glucometer Dex 2 uses a disk of 10 strips, and the Accu-Chek Compact uses a test drum containing 17 strips. The strip and drum are inserted into the meter prior to use and remain there until all strips are depleted. With Automated Drum Technology, as found in the Accu-Chek Compact, the patient merely presses a button, causing the strip to issue from the meter, to which the patient applies the blood sample. However, cost may be a deterrent for some patients; the strips for the Accu-Chek Compact are among the most expensive.

Some meters require the user to insert a strip or chip into the meter when a new package is purchased so that the meter might be calibrated. Others require the user to manipulate a button until the code displayed matches the code of the package of strips. For both products with enclosed test strips (e.g., Glucometer Dex 2, Accu-Chek Compact), calibration occurs automatically when the patient places the cartridge/drum inside the meter.
