Abstract
A disposable, self-administered electrolyte test is affixed to the label of a commercially available electrolyte supplement, is available in the pharmacy section of a retail store, or is distributed by a physician or a clinic.
Claims18
A disposable electrolyte test in the form of a substantially flat package, the electrolyte test comprising:
- a. a flat, planar substrate;
- b. a sample-receiving region on the substrate;
- c. an ion-sensor cartridge in fluid communication with the sample-receiving region;
- d. an indicator on the substrate adjacent the sample-receiving region;
- and
- e. circuitry for operating the ion-sensor cartridge and the indicator so as to cause display, on the indicator, of an ionic parameter in response to the presence of a sample on the sample-receiving region.

A method of performing an electrolyte test, the method comprising:
- a. providing an electrolyte test element comprising a flat, planar substrate, a sample-receiving region on the substrate, an ion-sensor cartridge in fluid communication with the sample-receiving region, and an indicator responsive to the ion-sensor cartridge;
- b. receiving a sample on the sample-receiving region;
- and
- c. operating the ion-sensor cartridge and the indicator so as to cause display, on the indicator, of an ionic parameter of the sample.
