The reason for not having a high glutamate but a high ratio is a physiologic difference. The ratio of the two is clinically significant only if the glutamine-glutamine index is abnormal. Glutamate aminotransferase (glutamate) and glutamate aminotransferase (glutamate) are important indicators of clinical liver function tests, the normal range of glutamate is 5-40 U/L, the normal range of glutamate is 8-40 U/L, and glutamate/glutamate is ≤1. When liver function is impaired, these two enzymes are released into the blood, making the laboratory indicators higher than normal, and then clinicians may pay attention to the ratio of the two, and an elevated ratio of the two can indicate more serious liver injury. If the values are normal, the ratio has no clinical significance. Glutamate C reflects hepatocyte damage, while glutamate C reflects hepatocyte necrosis. It is a very accurate test for cirrhosis, liver fibrosis, and liver cancer. In the case of liver enzyme abnormality, glutamic acid/glutamic acid <1 suggests hepatocellular damage. In case of abnormalities, active medical attention is recommended.
