Measured albumin concentrations

Albumin (g/L)	Mean ± SD (range)	CV (%)
30	27.2 ± 1.0 (26.3–29.0)	3.5
25	22.6 ± 0.9 (21.5–24.3)	4.0
20a	18 ± 0.7 (17.3–19.2)	3.7
15	13.3 ± 0.7 (12.5–14.6)	5.3
10a	8.9 ± 0.6 (8.1–10.0)	6.8

Data represent the results of ten laboratories for the measured concentrations of EQA samples 6 to 20 shown in Table 1 with albumin concentrations ranging from 10 to 30 g/L. Results are expressed as mean ± SD (ranges) with interlaboratory coefficients of variation (CV) per concentration (percentage)

^aAlbumin concentrations of 10 and 20 g/L describe mean albumin concentrations of samples with six different bilirubin concentrations
