Abstract

Systems and methods for multiple analyte analysis are provided. In one embodiment, a method includes determining concentrations of first and second analytes in a sample. The first and second analytes may be, for example, glucose and hydroxybutyrate. In this form, an indication related to the measured concentration of hydroxybutyrate is provided in response to determining that the concentration of hydroxybutyrate is above a predetermined value. In a further aspect of this form, a quantitative indication representative of the measured glucose concentration is automatically provided regardless of the value of the measured glucose concentration. In another embodiment, a system includes a meter configured to interact with a test element to assess first and second analytes in a sample. Further embodiments, forms, objects, features, advantages, aspects, and benefits shall become apparent from the description and drawings.

Dependent claims

A method, comprising:

performing a plurality of tests to determine concentrations of first and second analytes in a sample via a test meter configured to interact with test elements, wherein each of the tests includes applying the sample to a test element configured for electrochemically analyzing the first and second analytes in the sample, and wherein the first analyte is a ketone and the second analyte is glucose;
storing, in a memory of the test meter, the first analyte concentration and the second analyte concentration determined from each test performed;
automatically providing the second analyte concentration on at least a first portion of a display of the test meter from each test performed;
analyzing the stored concentrations of the first analyte to monitor for an existence of an upwardly increasing trend in the stored concentrations toward a predetermined value of about 0.6 mM regardless of the second analyte concentration;
and
providing a first indication in response to detecting the existence of the trend on at least a second portion of the display screen of the test meter regardless of the second analyte concentration.
