Claim 31:
32. The method of claim 10, wherein the method further comprises:
performing a second immunoassay to measure a level of a second prostate antigen in the sample, wherein the second prostate antigen is human kallikrein 2 (hK2);
performing the second immunoassay to measure the level of the second prostate antigen in each titer in a second set of prostate antigen standards, wherein the second set of prostate antigen standards comprises between 5 and 15 titers containing known levels of the second prostate antigen, wherein the level of the second prostate antigen in the largest titer in the second set is less than or equal to 8 ng/mL hK2, wherein each intermediate titer of the second set of prostate antigen standards is equidistant from the titer above and below it on a logarithmic scale, and wherein the quantity of the smallest non-zero titer of the second set is below the limit of quantification of the second immunoassay; and
determining the level of the second prostate antigen in the sample based on the measured levels of the second prostate antigen in the second set of prostate antigen standards.
