Electrochemical method of testing oxidative stress

Abstract

A method of determining oxidative stress in asubject, comprising : obtaining a biofluid sample from the subject; acquiring an electrochemical signal from the sample with the aid of an array of bare and surf ace -modi fied electrodes that is sensitive towards a model antioxidant and a model oxidant; optionally preprocessing the electrochemical signal, to obtain processed data; applying trained chemometric model ( s ) to the processed or raw data, to measure TAG and TOS levels; and determining a status of oxidative stress in the subject based on the measured TAG, TOS or the TOS : TAG ratio.
