Normal values for ALT range between 5 - 45U/L. Your value is also considered under normal change.
Usually grossly elevated ALT levels suggest liver damage or death of hepatocytes, inflammation or infcetion of
liver tissue etc. Best.

The normal range of values for ALT (SGPT) is from 7 to 56 units per liter of serum (the range can vary
slightly from lab to lab). So, as Dr Veena pointed out, the value of 46 is normal.
However, just for your information: Many a times AST (SGOT) and ALT OR SGPT (both are collectively called
transaminases) rise without any cause. Causes of liver transaminase elevations include viral hepatitis,
alcohol use, medication use, steatosis or steatohepatitis, and cirrhosis. Steatosis and cirrhosis are ruled
out by the ultrasound. Other common health conditions, such as diabetes, heart disease, pancreatitis,
hemolytic anemia and thyroid disease, can also cause liver transaminase elevations. Most liver diseases are
characterized by greater ALT elevations than AST elevations except cirrhosis and alcohol abuse. ALT also rises
in bile duct obstruction due to stone or tumor.
All conditions which cause an increase in AST or ALT show a marked rise above the normal range. Hope this
helps! Take care!
