The normal range for the AST (aspartate aminotransferase) enzyme in adult men is roughly 5 to 40 units per liter, while the ideal range for ALT (alanine aminotransferase) is 7 to 56 units per liter of serum. Normal test values for women and children differ slightly, explains Medicine Net.

Liver function tests also indicate normal ranges to be 3.5 to 5.0 g/dL for albumin, 0.1 to 1.0 mg/dL for bilirubin, platelet counts of 150,000 to 400,000 per microliter and clotting, or, “coagulation” ranging from 9.5 to 13.8 seconds.

Normal levels of the GGT enzyme (gamma-glutamyl transpeptidase), ALP enzyme (alkaline phosphatase) and LD enzyme (lactate dehydrogenase) are about 9 to 48 units per liter, 45 to 115 U/L and 122 to 222 U/L, respectively. Blood tests indicating higher levels of any of the enzymes could suggest injury, bleeding, damage and diseases to the liver or other conditions.
