Serum total protein: 60-80 g/L (gram/liter) Serum albumin: normal: 40~55g/L Serum globulin: normal: 20~30g/L Albumin/globulin ratio (A/G): 1.-2., Alanine aminotransferase (ALT): 5-40 U/L (unit/liter) Aspartate aminotransferase (AST): 8-40U/L (unit/liter) ALT/AST≤1; Total bilirubin (STB): 1.71-17.1μmol/L (micromolar/liter) Direct bilirubin (CB): 1.71-7μmol/L (1-4mg/L). Indirect bilirubin (UCB): 1.7-13.7μmol/L. wait. Inspection precautions: 1. Inspection on an empty stomach; 2. No strenuous activities; 3. Try to avoid liver function tests during intravenous infusion or within 4 hours of medication; 4. Do not eat foods rich in carotene and lutein.
