summary

What is the normal value of transaminase? Transaminase is the most sensitive index to judge whether the liver is damaged or not. Understanding the normal value of transaminase can make patients better grasp their own liver conditions, so as to attract attention when liver problems occur. Let me talk about the normal value of transaminase today

What is the normal value of transaminase

First of all, the normal value of glutamic oxaloacetic transaminase, which is abbreviated as got or ast, is an important indicator of liver function test. The content of glutamic oxaloacetic transaminase is the highest in myocardial cells, but its serum concentration can also increase when the liver is damaged. It is often used as an auxiliary examination for myocardial infarction and myocarditis in clinic. The normal value of ALT was 0-40 μ g / L. when ALT increased significantly and AST / ALT ratio was more than 1, it indicated that there was damage of liver parenchyma.

Secondly, alanine aminotransferase (ALT or GPT) is the main transaminase in liver function examination. 1% of liver cell damage can double the concentration of ALT in blood. Therefore, ALT level can be more sensitive to monitor whether the liver is damaged. The level of alanine aminotransferase is normal in the range of 0-40 μ / L. If it is beyond the normal range, the doctor will recommend another check to eliminate the possibility of errors caused by laboratory equipment failure and operation errors.

Finally, transaminase mainly exists in hepatocytes, including alanine aminotransferase and aspartate aminotransferase. When hepatocytes are inflamed and necrotic, transaminase is released into hepatocytes, which will cause the increase of transaminase concentration. Therefore, high transaminase generally indicates liver damage.

matters needing attention

The normal value of transaminase and high transaminase are common in patients with liver diseases. The harm of high transaminase is different in different patients with liver diseases. Therefore, it is necessary to remind the patients with elevated transaminase to check in time, so as not to bring greater harm to their health.
