The standard is supplied with the TAS kit, simplifying the ordering process.
Dedicated TAS control available
Dedicated TAS control available offering a complete testing package.
Applications available detailing instrument-specific settings for the convenient use of the Randox TAS assay on a variety of clinical chemistry analsyers.
Free radicals / reactive oxygen species (ROS) are produced during normal cellular metabolism, however, can have harmful effects. Antioxidants are the first line of defence and are produced by the body to neutralise the harmful effects of ROS, preventing cellular damage 1,2, 3. Measuring total antioxidant status (TAS) can provide information on an individual’s overall antioxidant status, which may include antioxidants not yet recognised or not easily measured. The TAS of a sample is a quantitative measurement of the state of balance of the various components (exerting actions in different way) under specified reaction conditions 4.
Reduced levels of total antioxidant status (TAS) is indicative of oxidative stress and increased susceptibility to oxidative damage 5. Oxidative stress is an imbalance between the ROS and antioxidants in the body, favouring ROS 6. Oxidative stress is associated with several health conditions, including: chronic inflammation, neurodegenerative diseases such as Alzheimer’s disease and Parkinson’s disease, cancer and CVD 7.
