1. A method for identifying control/calibration data generated by a medical device, the method comprising the steps of:
- (a) providing a control/calibration solution containing at least one analyte and containing a sufficient amount of a modulator to cause the solution to provide two electrochemical responses to an applied signal, wherein one electrochemical response is characteristic of blood and one electrochemical response is uncharacteristic of blood wherein said modulator is selected from the group consisting of an ionic modulator, and a combination of an ionic modulator and an organic modulator;
(b) applying a signal containing AC and DC components to the control/calibration solution;
(c) measuring the two electrochemical responses;
(d) using the characteristic electrochemical response to provide control/calibration data; and
(e) using the uncharacteristic electrochemical response to identify control/calibration data.

Abstract
Control and calibration solutions are described that provide control and calibration data that is recognized by a test meter allowing the meter to segregate the control and calibration data from regular test data. Recognition and segregation of the control and calibration data can occur automatically with no additional input from the meter'"'"'s user. Methods for use of the solutions are also provided.
