Abstract:
1. A method for determining the concentration of glucose in blood, a blood fraction or a control, the blood, blood fraction or control including red blood cells or red blood cell fractions which affect the determination of the concentration of glucose, the method including performing a first measurement on the blood, blood fraction or control which first measurement varies with both the concentration of glucose and at least one of the presence and concentration of red blood cells or red blood cell fractions, which first measurement comprises a measurement of a time-varying function i 1 (t) having the general form where t is time from initiating the measurement, M is the slope of a graph of the function and B is a value the function approaches as t becomes very large, performing a second measurement on the blood, a blood fraction or control which second measurement has the form of a time-varying function i 2 (t), where t is time, t<some arbitrarily established time, i 2 (t) varying primarily only with the at least one of the presence and concentration of red blood cells or red blood cell fractions to develop an indication of the at least one of the presence and concentration of red blood cells or red blood cell fractions, and removing an amount representative of the indicated presence or concentration of red blood cells or red blood cell fractions from the concentration of glucose indicated by the first measurement to provide the concentration of glucose in the blood, blood fraction or control.
