What is the reference range for ALT?
A normal ALT test result can range from 7 to 55 units per liter (U/L). Levels are normally higher in men. Slightly high ALT levels may be caused by: Alcohol abuse.
What is an elevated level of ALT?
When liver cells are damaged, they release ALT into the bloodstream. An ALT test measures the amount of ALT in the blood. High levels of ALT in the blood can indicate a liver problem, even before you have signs of liver disease, such as jaundice, a condition that causes your skin and eyes to turn yellow.
Is ALT level of 52 high?
Typically the range for normal AST is reported between 10 to 40 units per liter and ALT between 7 to 56 units per liter. Mild elevations are generally considered to be 2-3 times higher than the normal range.
Is 65 a high ALT level?
What ALT level is considered high? The upper limit of normal for ALT is 55 IU/L. When an ALT level is double to triple the upper limit of normal, it is considered mildly elevated. Severely elevated ALT levels found in liver disease are often 50 times the upper limit of normal.
What is the upper limit of normal for ALT?
The upper limit of normal (ULN) for serum alanine aminotransferase (ALT) has long been used as 40 IU/L. However, this value was determined before the introduction of anti-HCV testing and establishment of the concept of nonalcoholic fatty liver disease (NAFLD).
What’s the normal range for an alt blood test?
ALT blood test normal range: Normal ALT are less than 36U/L [7 to 55 units per liter (U/L)]. This result is typical for adult men. Normal results vary from laboratory to laboratory and might be slightly different for women and children (neonate < 50 U/L).

What is the normal ALT level for Hep C?
upper limits for normal ALT to be as low as 30 U/L for males and 19 U/L. for females.3 In addition, ALT activity in patients with viral hepatitis, who. achieved sustained virologic response, was often below 30 U/L.
What should the AST / ALT ratio be in liver disease?
The AST/ALT ratio is typically > 1 in alcoholic liver disease and AST/ALT < 1 in non-alcoholic liver disease. ALT may be elevated in skeletal muscle disease but the degree of elevation is much less than for AST (aspartate aminotransferase) and CK (creatine kinase).
