Answer

Two different reference ranges are used in troponin assays. The upper percentile reference limit gives the upper limit of what can be expected in a normal, healthy, adult population, while the coefficient of variation (CV) is the percent variation in assay results that can be expected when the same sample is repeatedly analyzed.
