What is the normal range for ALT? Different labs use different ranges, but the typical range is about 7 to 56 units per liter (U/L) of blood. What level of ALT is concerning?
The normal range for alanine transaminase (ALT) varies from laboratory to laboratory. One common reference range for an ALT blood test is 7 to 56 U/L (units per liter). ALT levels are typically higher in people assigned male at birth than in people assigned female at birth.
ALT is the most specific enzyme to the liver itself. Typical ranges can vary between the sexes, based on age and at different laboratories. Generally speaking, the upper limit of typical for AST and ALT for men is 35 to 40 units per liter (U/L) and for women is 25 to 30 U/L.
The AST normal range is typically between 5 to 40 units per liter of serum, while the ALT normal range is generally from 7 to 56 units per liter of serum. Even in conditions when AST and ALT are very elevated, the liver still may function properly.
Normal levels of ALT (SGPT) ranges from about 7-56 units/liter of serum (the liquid part of the blood), Normal levels of AST (SGOT) is about 5-40 units/liter of serum. Elevated levels of AST and ALT may signify the level of liver damage in a person.
Standard range blood test results for typical liver function tests include: ALT. 7 to 55 units per liter (U/L). AST. 8 to 48 U/L. ALP. 40 to 129 U/L. Albumin. 3.5 to 5.0 grams per deciliter (g/dL). Total protein. 6.3 to 7.9 g/dL. Bilirubin. 0.1 to 1.2 milligrams per deciliter (mg/dL). GGT. 8 to 61 U/L. LD. 122 to 222 U/L. PT. 9.4 to 12.5 seconds.
The normal range of SGPT levels varies slightly depending on the laboratory standards but typically falls between 7 to 56 units per liter (U/L) of blood. Normal SGPT range for males: 10 to 40 U/L Normal SGPT range for females: 7 to 35 U/L
