肝功检查（Liver function tests） How to look at the liver function test indicators Liver function tests (representing changes in the liver itself): Reference scope of project unit Total protein G/L 60-83 Albumin G/L 35-53 Globulin G/L 25-33 Alanine aminotransferase U/L 0-40 U/L 0-50 aspartate aminotransferase Total bilirubin umo/l 0-20 Direct bilirubin umo/l, 0.0-6.0 The clinical significance of liver function test indicators: Liver function test indicators generally do including alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma glutamyl transferase (GGT), albumin / globulin (A/G), total bilirubin (T-Bil), direct bilirubin (D-Bil). ALT and AST were mainly distributed in liver cells, if the necrosis of liver cells, ALT and AST will be increased, but the distribution of these two enzymes in the liver cells is different, ALT distributed in the cytoplasm of hepatocytes, AST distribution in plasma and liver mitochondria. Mild acute hepatitis and chronic hepatitis, mainly for the increase of ALT, therefore, AST/ALT1; late chronic hepatitis, cirrhosis and liver cancer patients, the extent of damage of liver cells is serious, mitochondria also suffered serious damage, therefore, AST increased significantly, AST/ALT 1 or even 2. ALP and GGT increased significantly in cholestatic hepatitis and extrahepatic obstruction, and elevated GGT in patients with alcoholic hepatitis. Albumin is produced in the liver, when impaired liver function, reduce albumin, globulin, immune organ is made, when the body has the enemy, increase the ball protein produced, and chronic hepatitis patients because of liver dysfunction, decreased albumin, and in vivo in the presence of hepatitis B virus due to the enemy, increase globulin, caused by the ratio of A/G inversion. When the liver cells are damaged, the metabolism and discharge of bilirubin are impaired. Therefore, both T-Bil and D -Bil increase. Liver function test of liver The liver is the central or
