Glutathione, Total

This test measures the total amount of glutathione in your blood, a substance that acts as a major antioxidant to protect your cells from damage. It helps show how well your body is managing oxidative stress, a process where harmful molecules can injure tissues. Doctors use these results to evaluate nutritional status or to look for signs of stress on the liver, kidneys, or immune system. However, this test cannot diagnose a specific illness by itself and requires other medical findings to confirm the cause of abnormal levels.
