Oxidative Stress Markers

Meaning

Oxidative stress markers are measurable biological molecules whose concentration or modification reflects an imbalance between the production of reactive oxygen species (ROS) and the body’s ability to detoxify these reactive intermediates or repair the resulting damage. Clinically, elevated levels of these markers, such as malondialdehyde (MDA) or oxidized low-density lipoprotein (ox-LDL), indicate cellular damage to lipids, proteins, or DNA. This condition is strongly implicated in the pathogenesis of numerous age-related diseases and chronic metabolic disorders. Monitoring these markers provides a tangible assessment of cellular health and longevity.
