肝功能正常值（Normal liver function value） Normal liver function value Liver function tests reflect liver function tests, liver function tests, including ALT, AST, usually AST/ALT, GGT, ALP, TBILI, DBILI, IBILI, TP, ALB, GLB, A/G, LDH-L, Ch, SF, PA and other projects, to understand the examination index of the standard, will help increase the understanding and diagnosis the liver function in people. Check item 1 serum protein Serum total protein: 60-80 g/L (Ke /sheng) Serum albumin: normal: 40~55g/L Serum globulin: normal: 20~30g/L Albumin / globulin ratio (A/G):1.-2.: The detection of serum total protein and albumin is the key index to reflect the liver function. Because the liver has a strong compensatory ability, and albumin half-life and other reasons, so only when the liver damage changes to serum total protein and albumin and to a certain extent, while acute or partial liver injury of these two indicators were normal. Therefore, the detection of serum total protein and albumin is mostly used to reflect chronic liver damage and reflect the reserve function of hepatic parenchymal cells. The decrease in total protein usually occurs with albumin reduction, and the increase in total protein is often accompanied by an increase in globulin. 2, commonly used serum enzyme Alanine aminotransferase (ALT),:5-40, U/L (unit / liter) Aspartate aminotransferase (AST) and:8-40U/L (unit / L) ALT /AST = 1 Two: increase in response to acute and chronic viral hepatitis, liver cirrhosis, liver cancer, fatty liver, cholecystitis, cholangitis, acute myocardial infarction, myocarditis, polymyositis, death into alcoholic hepatitis (AST increased significantly); Two hepatitis can be significantly elevated; jaundice early, often AST AST ALT ALT, long recovery period; ALT recovery; increased two, indicating chronic hepatitis; the ratio of AST/ALT is less than 1, may be chronic persistent hepatitis; enzyme activity increased and AST/ALT ratio greater than 1 can be chronic activity hepatitis. 3,
