Estimates of imprecision of multiplexed analytes in serum and saliva using pooled quality control materials.

CV, % coefficient of variation; AI, ratio of analytical imprecision (CV of QC materials) over interindividual variation (CV of all participant values) with a target value of <0.25; QC data for IL-1β and IL-8 were insufficient in saliva, no data is reported; Bolded Adjusted Between Run CV indicate analytes that are in the acceptable range (<25%) for imprecision.
