Glutathione is an intracellularly distributed enzyme that is widely present in human hepatocytes, cardiomyocytes, skeletal muscle cells, etc. Under normal conditions, its concentration in the blood is low, usually in the range of 0-40 U/L. When the above-mentioned cells are damaged or necrotic for various reasons, the concentration in the blood will rise. Under normal circumstances, its concentration in the blood is low, usually in the range of 0-40 U/L. When the above cells are damaged or necrotic for various reasons, the concentration in the blood will increase, prompting clinicians to detect and diagnose certain diseases. Among the common causes of elevated glutathione transaminase are: i. Hepatitis, including cell damage caused by various viral hepatitis, can appear in the blood as a significant increase in glutathione transaminase and glutathione transaminase. Second, myocardial infarction or myocarditis, both of which can also show elevated glutathione aminotransferase. Third, glutathione transaminase can also be elevated in certain conditions such as pneumonia, nephritis, or severe muscle damage or muscle crush syndrome. Therefore, when glutamic transaminase is elevated, the final diagnosis of the disease should be made through medical history, careful physical examination, and other necessary auxiliary tests.
