Oxidative damage can be assessed using various biomarkers. For instance, malondialdehyde (MDA) is a widely used marker for lipid peroxidation. Protein carbonyl content serves as an indicator of protein oxidation, while 8-hydroxydeoxyguanosine (8-OHdG) is a marker for oxidative DNA damage. These biomarkers can be measured in blood, urine, or tissue samples to evaluate the extent of oxidative stress and damage.
