Correlation between the detection limit in the MM6-CA8 culture test system and that in the human whole blood culture test system. The detection limit for each pyrogen was defined as the minimum concentration of that pyrogen inducing a significant amount of cytokine production (greater than 2 standard deviations above that obtained with 0 ng of pyrogen/ml). The correlation is expressed for every cytokine; r, linear correlation coefficient.
