Extended data:
Relevant requirements for liver function examination stipulate that:
1, HPT in patients with acute hepatitis, chronic active hepatitis, liver cirrhosis and subacute severe hepatitis decreased at all stages of the course. The more serious the condition, the lower the HPT.
2. When liver disease develops to hepatocyte failure, its HPT drops obviously, generally below 0.5. If HPT gradually recovers in turn, the prognosis is good.
3. All liver function tests require fasting blood collection. This is because normal people's blood contains a certain amount of macromolecules β and γ globulin, which can be combined with some chemical reagents to precipitate, while small molecules of albumin and α 1- globulin can prevent precipitation.
