Establishment of a Method for Measuring Antioxidant Capacity in Urine, Based on Oxidation Reduction Potential and Redox Couple I₂/KI

Table 1

The determination of precision for I₂/KI redox potential method.

Group	(mV)	In-run		Between-day
		SD	CV (%)	SD	CV (%)
Control	415.93	0.79	0.19	1.79	0.43
Low	407.89	0.45	0.11	1.59	0.39
High	398.58	0.80	0.20	1.71	0.43

Control, electrode solution with no urine; low, electrode solution with 50% concentration urine; high, electrode solution with 100% concentration urine.
