Generally speaking, liver function transaminase increases, indicating that liver cells are damaged. When liver cells are damaged, the structure of liver cells changes to varying degrees, or the permeability increases, or the cell membrane is damaged, or even the nucleus is damaged. At this time, in liver cells? Liver enzyme? It is released into the blood, resulting in an increase in the level of liver function transaminase in the blood.
So, does high liver transaminase mean there is? Hepatitis? And then what? Liver function transaminase is high, which may be pathological or physiological In other words, in the absence of hepatitis or other diseases, liver function transaminase may also increase. So, how to distinguish? My cousin gave some advice.
First, under what circumstances will there be a physiological increase in liver function transaminase?
1, massive post-exercise sampling: If there is a large amount of exercise before liver function examination, especially running exercise, it will cause short-term damage to cells such as skeletal muscle. Does it also exist in these cells? Liver enzyme? Although it is not as obvious as in liver cells, sampling after exercise will also increase the content of serum transaminase.
2, sampling after a full meal: many doctors will remind you not to eat breakfast before liver function test, but there will be many friends? Disobedient? . After a full meal, the blood composition indexes changed obviously, including various transaminase.
3. Pregnancy: During pregnancy, may the level of liver function transaminase appear? Stress? Sexual increase, although caused by liver cell injury, can not be defined as hepatitis. During pregnancy, a slight increase in liver function transaminase can still be regarded as a physiological increase.
Second, under what circumstances is there a pathological increase in liver function transaminase?
1, various active hepatitis: At present, the common hepatitis types are fatty liver, drug-induced liver and viral hepatitis. When these hepatitis types progress, liver function transaminase will continue to be high.
2. When taking certain drugs: What are some drugs? Hepatotoxicity? Sex can cause damage to liver cells, such as some cold medicines and tuberculosis medicines.
Third, how to distinguish pathological elevation from physiological elevation.
1. Behavior recovery before examination: that is, before liver function sampling, determine whether you have stayed up late, drunk, had a full meal, exercised vigorously, etc. If so, check it again at regular intervals after eliminating these factors.
2. Hepatitis screening: Fatty liver, viral hepatitis and hepatobiliary ultrasound can basically determine whether the high transaminase of liver function is caused by pathological factors.
3, increase the number of examinations: occasionally transaminase is high, it is impossible to determine whether it is pathological or physiological, unless it is very high. Therefore, if the transaminase is high in the process of applying for employment or health certificate, you can apply for multiple re-examination within the deadline.
Cousin of the provincial doctor reminded that liver function transaminase is only a sensitive index of progressive liver cell injury, and it is generally not used alone to judge the condition. Therefore, to distinguish between pathological elevation and physiological elevation, we must check it clearly and review it regularly.
