Free radicals/antioxidant measurement and monitoring

Free radicals/antioxidant measurement and monitoring

The role of free radicals and antioxidants is now becoming well documented and understood. Identification of individuals with reduced antioxidant protection and therefore those with increased susceptibility to free radical associated disease, has well proven benefits.

NPTech Services has announced the availability of a package of diagnostic/monitoring tests in the area of free radicals/antioxidant management:

1. 1.

   The first, and only, point of care analyser for measurement and monitoring of free-radicals. This small, cost effective system provides a result in six minutes from a fingerprick blood sample. Non-technically qualified personnel are easily trained to provide accurate, reliable results.

2. 2.

   A panel of laboratory-based reference or back-up tests (carried out at NPTech Services' clinical laboratory based in Newmarket, Suffolk). These include:

3. 3.
   • •

     Superoxide dismutase,

   • •

     Glutathione peroxide,

   • •

     Glutathione reductase,

   • •

     Total antioxidant status,

   • •

     Reactive oxygen metabolites.

4. 4.

   A self/home test (based on a urine sample) for monitoring levels of malondialdehyde (MDA) as an indicator of oxidative stress (excess of free radicals). MDA is the immediate by-product of the oxidative action of free radicals on cell membranes by the process of lipid peroxidation. Measurement of MDA is an accepted measurement of oxidative stress. Up until now, this has required laboratory testing.
