In the past, the liver function test needed to draw blood on an empty stomach in the morning. Some scholars have measured the serum transaminase activity of hepatitis patients in the early, middle and late days of fasting, and found that it fluctuates greatly. So it is better to check the serum transaminase.
It is best to limit it to once, and it is best in the morning for the convenience of work, not necessarily on an empty stomach. But it is best to check protein, lipid and glucose metabolism in liver function on an empty stomach, because serum protein, lipid and glucose are all possible after eating.
Has changed.
Examination of liver function after meals will lead to abnormal activity detection of some enzymes in liver function.
If transaminase is high, it is recommended that liver function be fasted for 6-8 hours.
Liver function examination should be done on an empty stomach in the morning, and alcohol, greasy diet and overeating should be avoided the day before the examination.
