Alanine aminotransferase (ALT) is an enzyme found mostly in liver cells. Apart from the liver, it is also found in heart and muscle cells. The function of ALT is to convert alanine into pyruvate, for cellular energy production (Chen et al., 2004).
What is the function of ALT in liver?
Alanine aminotransferase (ALT) is an enzyme found inside liver cells. Liver enzymes, including ALT, help your liver break down proteins to make them easier for your body to absorb. When your liver is damaged or inflamed, it can release ALT into your bloodstream.
What is the function of AST and ALT?
ALT is an enzyme found in the liver that helps convert proteins into energy for the liver cells. When the liver is damaged, ALT is released into the bloodstream and levels increase. Aspartate transaminase (AST). AST is an enzyme that helps metabolize amino acids.
What is the principle of alanine aminotransferase?
PRINCIPLE: ALT catalyzes the reaction between L-alanine and 2-oxoglutarate. The pyruvate formed is reduced by NADH in a reaction catalyzed by lactate dehydrogenase (LDH) to form L-lactate and NAD+. The rate of the NADH oxidation is directly proportional to the catalytic ALT activity.
What is alanine aminotransferase in blood test?
ALT, which stands for alanine transaminase, is an enzyme found mostly in the liver. When liver cells are damaged, they release ALT into the bloodstream. An ALT test measures the amount of ALT in the blood.
What is alanine aminotransferase normal range?
The normal range is 4 to 36 U/L. Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or may test different samples.

What is high alanine aminotransferase ALT?
What does it mean if my alanine transaminase (ALT) is high? High levels of ALT in your blood can be due to damage or injury to the cells in your liver. An increased ALT level may indicate the following conditions: Alcohol-induced liver injury. Fatty liver disease (too much fat in your liver).
What is the most important liver function test?
Serum albumin test.
This test is used to measure the level of albumin (a protein in the blood) and may be useful in the diagnosis of liver disease. Low levels of albumin may indicate the liver is not functioning properly.
When should I worry about ALT?
When ALT levels are very high, it may be a sign of an acute liver problem. Mild or moderate elevation, especially if it persists on several tests over time, can be an indicator of a chronic disease. However, the degree of elevation alone is not a reliable predictor of the extent of injury to the liver.
What happens if alkaline phosphatase is high in liver?

Does fatty liver cause high ALT?
The alanine aminotransferase (ALT) is a specific marker for liver inflammation and is typically elevated in individuals with a fatty liver. If your ALT test results are elevated, your doctor may order additional blood tests to check for other conditions including viral hepatitis.
Can liver damage reversed?
The liver damage done by cirrhosis generally can’t be undone. But if liver cirrhosis is diagnosed early and the cause is treated, further damage can be limited and, rarely, reversed.
How do I know if my liver is healthy?
An AST level under 40 IU/L is considered normal. High GGT levels can be a sign of liver damage or disease. If you drink too much alcohol, your GGT levels usually increase.
