The Ox-LDL test evaluates oxidative stress and cardiovascular risk by measuring oxidized LDL levels. High Ox-LDL levels can indicate increased risk of atherosclerosis and related cardiovascular conditions such as heart disease and stroke. Symptoms of these conditions may include chest pain, shortness of breath, and other signs of cardiovascular distress. The test helps diagnose and manage cardiovascular health by assessing the impact of oxidative stress on the arteries and guiding treatment strategies.
