Oxidative Stress Analysis (free radical and antioxidant test)

During the course of your normal everyday metabolic activity, including workouts, digestion, energy production, detoxification of pollutants and immunologic defense mechanisms, free radicals are produced. Unfortunately, these free radicals are unstable molecules that can extract an electron from a neighboring molecule, causing damage in the process to cells, skin, joints, organs and other crucial body tissues.

Unchecked free radical production accelerates the pathogenesis of human disease and aging. But these free radicals are counter-balanced by the anti-oxidants present in foods and supplements) Dietary antioxidants (such as proanthocyanidins found in blueberries and bioflavonoids found in citrus fruits), as well as the antioxidant enzymes, and antioxidant supplements such as superoxide dismutase and glutathione peroxidase, provide critical protection against free radical damage. Oxidative stress results when this delicate pro-oxidant/antioxidant equilibrium is disrupted in favor of the pro-oxidant (free radical) state.

An oxidative stress analysis, the gold-standard test for antioxidants and free radical damage, is used to access the balance between oxidative damage by free radicals and how well your body can “quench” those free radicals. Unchecked oxidative damage by free radicals can promote disease, accelerate aging, and decrease physical performance and recovery, and many people are walking around with either insufficient antioxidant production, tons of inflammation and free radicals or, worse yet, both.

Evidence is mounting that oxidative stress is involved in an enormous number of disease processes, including:

  • Rheumatoid arthritis
  • Asthma
  • Cancer
  • Macular Degeneration
  • Inflammatory Bowel Disease (IBD)
  • Neurodegenerative diseases such as Parkinson's and Alzheimer's
  • Arthritis
  • Diabetes Mellitus
  • Atherosclerosis
  • Chronic Fatigue Syndrome
  • Environmental Sensitivities

The oxidative stress analysis takes a look at your blood to determine how equipped you are to protect against these free radical ravages, and which antioxidants you are or are not deficient in.

The test utilizes a small blood sample (collected in any LabCorp lab near your home) in order to evaluate your body's oxidative stress status and antioxidant reserve. This nutritional test can help you or your medical practitioner then assess equilibrium between oxidative damage and antioxidant reserve. It is necessary to address all three components that this test inspects:

1) The antioxidant reserve capacity that provides protection against free radicals;

2) The presence or absence of enzymes that quench those free radicals, and;

3) The damage that free radical production has already caused or is causing.
