Patent ID: 7312083

Claim:
A method of determining an assigned value corresponding to a concentration of an analyte in a target sample when measured using a first methodology, comprising the steps of: (a) determining a relative analyte concentration ratio by: (i) obtaining a first control sample concentration value, wherein the first control sample concentration value is determined by measuring the amount of the analyte in a control sample comprising the analyte using the first methodology; (ii) obtaining a second control sample concentration value, wherein the second control sample concentration value is determined by measuring the amount of the analyte in the control sample using a second methodology; (iii) adding the first control sample concentration value and the second control sample concentration value, thereby determining a summed control sample concentration value; (iv) dividing the first control sample concentration value by the summed control sample concentration value, thereby determining the relative analyte concentration ratio; (b) determining a summed target sample concentration value by: (i) obtaining a first target sample concentration value, wherein the first target sample concentration value is determined by measuring the amount of the analyte in the target sample using the first methodology; (ii) obtaining a second target sample concentration value, wherein the second target sample concentration value is determined by measuring the amount of the analyte in the target sample using the second methodology; (iii) adding the first target sample concentration value and the second target sample concentration value, thereby determining the summed target sample concentration value; and (c) determining the assigned value for the analyte in the target sample by multiplying the relative analyte concentration ratio and the summed target sample concentration value.
