Methods for testing oxidative stress

摘要

Method and compositions for determining oxidative stress in a subject are provided in which presence of an aldehyde in a biological fluid is correlated with an oxidative stress in a subject. A test reagent having a pH regulator, a reducing agent, and an aldehyde-reactive chromogen is mixed with the biological fluid, and the color of the resulting aldehyde-modified chromogen is correlated with the oxidative stress.
