i did liver function test and my ast was 19 (0-40 ) alt 68 ( 30-65) and all other tests was normal?

Question

what do you think cause for this elevation in ALT?
i did heaptitis b/c tests and they was negative , lat year i did ultrasonic for my abdomen and my liver was normal.

i dont complain of any disease.

Answer 1

Any kind of medicine or food can raise your ALT.Nothing to worry.

Answer 2

What are normal levels of AST and ALT?

The normal range of values for AST (SGOT) is from 5 to 40 units per liter of serum (the liquid part of the blood).

The normal range of values for ALT (SGPT) is from 7 to 56 units per liter of serum.

What do elevated AST and ALT mean?

AST (SGOT) and ALT (SGPT) are sensitive indicators of liver damage from different types of disease. But it must be emphasized that higher-than-normal levels of these liver enzymes should not be automatically equated with liver disease. They may mean liver problems or they may not. The interpretation of elevated AST and ALT levels depends upon the whole clinical picture and so it is best done by doctors experienced in evaluating liver disease.

The precise levels of these enzymes do not correlate well with the extent of liver damage or the prognosis (outlook). Thus, the exact levels of AST (SGOT) and ALT (SGPT) cannot be used to determine the degree of liver disease or predict the future. For example, patients with acute viral hepatitis A may develop very high AST and ALT levels (sometimes in the thousands of units/liter range). But most patients with acute viral hepatitis A recover fully without residual liver disease. For a contrasting example, patients with chronic hepatitis C infection typically have only a little elevation in their AST and ALT levels. Some of these patients may have quietly developed chronic liver disease such as chronic hepatitis and cirrhosis (advanced scarring of the liver).

So, your AST level of 19 is normal. But your ALT of 68 is high. ALT is the most sensitive marker for liver cell damage.


Mild to moderate elevations of the liver enzymes are commonplace. They are often unexpectedly encountered on routine blood screening tests in otherwise healthy individuals. The AST and ALT levels in such cases are usually between twice the upper limits of normal and several hundred units/liter. An overdose of Acetaminophen could cause this elevation.


The most common cause of mild to moderate elevations of these liver enzymes is fatty liver. In the United States, the most frequent cause of fatty liver is alcohol abuse. Other causes of fatty liver include diabetes mellitus and obesity. Chronic hepatitis C is also becoming an important cause of mild to moderate liver enzyme elevations Another cause to consider is inflammation of the gallbladder.

Answer 3

well its pretty much in normal range......68alt is nothing really to fuss about.......when you drink too much booze sometimes ur ast to alt ratio will be elevated to a ratio greater than 2:1... my ast and alt have been elevated above normal reference range before but it was due to gastic issues i was having....... who knows wot caused it i suppose.......its ur body doing its thing.....
