Method for improving the accuracy of the semi-quantitative determination of an alyte in fluid samples

摘要

Disclosed is an improved method for determining the concentration of a first analyte in a fluid test sample as a function of a second analyte also present in the sample whose concentration in the fluid sample is clinically related to that of the first analyte. The method involves determining the concentration of the first analyte, and, if this concentration is outside of its useful analytical range, dividing this concentration by the normal concentration of the second analyte. This method of ratioing the concentrations of the first and second analyte is advantageous because accuracy is increased with fewer false positive and false negative results being reported.
