The use of potentiometry to measure plasma antioxidant capacity to contribute to oxidative stress evaluation
is presented. In this assay, plasma (n = 60) diluted (0.3 to 1 ml) in phosphate buffer, pH 7.4, NaCl
9%, was submitted to potentiometry.
results demonstrate the adequacy of potentiometry for evaluating the antioxidant capacity of blood
plasma samples.
