Hello,
With the question “How are the AST and ALT levels, there is liver disease? ”, the doctor replied as follows:
AST (SGOT) is normally found in many organs such as liver, heart, muscles, kidneys and brain. It is released into the bloodstream when one of these organs is damaged.
ALT (SGPT) is found mostly in the liver. Although not the only enzyme present in the liver, the liver is where it is most concentrated. It is released into the bloodstream in the presence of liver damage. Therefore, it can be considered as a relatively specific indicator of liver status.
The SGOT test is not done alone, it is often done with the SGPT test. Based on the test results of liver enzymes increased more or less than normal values, SGOT or SGPT enzymes are more predominant, which will help doctors guide the diagnosis of causes of elevated liver enzymes.
In addition to liver diseases (such as viral hepatitis, toxic hepatitis ...), liver enzymes can also increase in other diseases besides the liver. If the liver enzyme test results increase below 5 times the upper limit of normal, and the SGOT index > SGPT, the patient may be in a state of heavy physical activity, hypothyroidism, muscle diseases, etc. hemolysis,... If SGOT In your case, the AST test result is slightly elevated above the normal range, but To know the cause of elevated liver enzymes, you need to visit a specialist, do some more tests to help the doctor have the most accurate diagnosis of your health condition.
