^aControls CI, CII, and CIII and samples S1, S2, S5, and S6 were tested one time per assay plate; whereas, samples S3, S4, S7, and S8 were tested three times per assay plate.

^bA result was included in the analysis if the reported value fell within the assay range of 15 to 480 EU/ml and the %CV did not exceed 25%. Results were excluded as follows: 78 values were <15 EU/ml, 15 values were >480 EU/ml, and 63 values had a %CV of >25%.
