What indicators do liver function tests mainly look at?

Mainly protein metabolism function, bilirubin and bile acid metabolism function of the liver.

Liver function test project includes: protein metabolic function, bilirubin and bile acid metabolic function, enzymology index, lipid metabolic function, liver excretion and detoxification function.

Protein examination related to liver function includes serum total protein, albumin to globulin ratio, blood turbidity and flocculation test, and alpha-fetoprotein examination. Serum enzymes related to liver diseases include alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and lactate dehydrogenase. Tests related to biotransformation and excretion include sodium sulfobromophthalein retention test.

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.
