A company tested two chemistry methods for the determination of serum glucose. Three pools of serum were used for the experiment. Each pool contained different levels of glucose through the addition of glucose to the base level of an existing serum pool. Three examples of serum from each pool were prepared independently for each level of glucose with each of the two chemistry methods. The concentration of glucose(mg/dl) for all samples was measured on one run of a spectrophotometer.
