The Oxidative Stress Analysis uses both blood or urine samples in order to evaluate the body’s oxidative stress status and antioxidant reserve. This test can help practitioners identify underlying causes and perpetuating factors for many clinical disorders and to customise specific treatment programs.
Free Radicals and Antioxidants
In the course of normal human activity – energy production, detoxification of pollutants and immunologic defense mechanisms, free radicals are produced. These free radicals are unstable molecules that can extract an electron from a neighboring molecule, causing damage in the process. Unchecked free radical production accelerates the pathogenesis of human disease and aging. These free radicals are counter-balanced by the anti-oxidants present in our foods (and supplements).
Dietary antioxidants (such as proanthocyanidins found in blueberries and bioflavonoids found in citrus fruits), as well as the antioxidant enzymes, superoxide dismutase and glutathione peroxidase, provide critical protection against free radical damage.
when this delicate pro-oxidant/antioxidant equilibrium is disrupted in favor of the pro-oxidant (free radical) state. Evidence is accumulating that oxidative stress is involved in many pathological processes, including
- Rheumatoid arthritis
- Diabetes mellitus
- Macular degeneration
- Chronic Fatigue Syndrome
- Inflammatory Bowel Disease
- Environmental sensitivity
- Neurodegenerative diseases such as Parkinson’s and Alzheimer’s
What is being measured.
To assess equilibrium between oxidative damage and antioxidant reserve, it is necessary to address
- The RESERVE capacity that provides protection
- The ENZYMES that quench the free radicals
- Evaluate the DAMAGE that free radical production has already caused
A blood sample measures anti-oxidant reserve and enzyme function including: whole blood glutathione, total anti-oxidant capacity, redox balance, and the enzymes superoxide dismutase and glutathione peroxidase. Additionally, blood markers of damage measure lipid peroxides (oxidative damage to cell membranes).
A urine sample to measure free radical damage, including lipid peroxides (oxidative damage to cell membranes) and 8-hydroxy-deoxyGuanosine (oxidative damage to DNA).
