Glutathione Test is a laboratory analysis used to measure glutathione levels in biological fluids such as plasma or cells. Glutathione is one of the body’s most powerful antioxidants, playing a vital role in protecting cells from damage caused by free radicals and oxidative stress. This test is primarily used to assess oxidative status and identify imbalances in biological processes. It may help diagnose and monitor health conditions such as chronic diseases, immune disorders, and liver diseases. It is also useful for evaluating the impact of various treatments on oxidative levels in the body. By measuring glutathione levels, physicians can guide treatment strategies and recommend nutritional supplements that may support overall health and enhance the body's ability to resist oxidative stress. This test is considered a valuable tool in modern medicine for understanding metabolic and oxidative health.
