About Glutathione peroxidase
What is glutathione peroxidase?
Glutathione peroxidase is an enzyme with antioxidant properties. It catalyses a reaction between antioxidant glutathione and hydrogen peroxide, removing the damaging hydrogen peroxide from cells to produce water and glutathione disulphide, which can be later recycled back to glutathione. The activity of glutathione peroxidase requires selenium, meaning the activity of glutathione peroxidase can indicate selenium levels in the body. Selenium deficiency can lead to problems with DNA synthesis, reproduction and thyroid activity.
Why take the test?
This test measures the activity of glutathione peroxidase. It is typically used to test for selenium deficiency.
