Plots indicating analytes with notable differences in CV or reliability between serum and EDTA plasma for 24 subjects. A) The ratio of CV (serum:EDTA plasma) is plotted in rank order from largest to smallest by analyte. Analytes with notably better CV in EDTA plasma (ratio >1.5; lower CV in plasma) and notably better CV in serum (CV ratio <0.667; lower CV in serum) are indicated B) The difference in reliability score between serum and plasma (serum minus plasma) is is plotted in rank order from largest to smallest by analyte. Analytes with notably better reliability in serum versus plasma (difference > +0.15) and better reliability in EDTA plasma versus serum (difference < −0.015) are indicated. Horizontal lines indicate descriptive cut-points used to define notable performance.
