Intra- and inter-assay precision tests of icELISA using MAb 1E9^a.

Concentration of AG (ng mL−1)	CV (%)
	Intra-assay (n = 6)	Inter-assay (n = 5)
62.5	3.86	8.75
31.3	3.07	6.48
15.6	1.28	4.39
7.81	1.87	3.60
3.91	1.59	3.82
1.95	1.50	2.88

^aAll values represent coefficient of variation (CV) calculated from formula as follow: CV = standard deviation (S.D.)/mean × 100.
