First Claim
Patent Images
1. A method for determining a concentration of a medically significant component of a biological fluid sample in contact with a reagent compound, comprising the steps of:
- a) applying a signal having an AC component to the biological fluid sample;
b) measuring a response to the signal;
c) determining an interferent correction based on the response; and
d) providing an indication of the concentration of the medically significant component, wherein the indication is corrected using the interferent correction;
wherein said signal comprises a multi-frequency excitation waveform formed by adding a plurality of individual waveforms of varying frequency together so that the fluid sample is excited by multiple frequencies at the same time such that the response contains measurement data collected simultaneously for all of the multiple frequencies.
