Alanine transaminase (ALT) is an enzyme found in the liver. It is used to measure the health of the liver and to diagnose liver diseases. An ALT blood test is a simple procedure that measures the amount of ALT in the blood. It is used to detect and monitor liver damage or disease.
What is the difference between ALT and AST?
ALT and aspartate transferase (AST) are both enzymes found in the liver. ALT is more specific to the liver than AST, so it is more commonly used to measure liver health. AST is found in other organs, so it is not as specific to the liver.
Why do I need an ALT blood test?
An ALT blood test is used for screening, monitoring, and diagnosing liver diseases. It can be used to detect liver damage, monitor the progression of a liver disease, or diagnose a liver condition. It can also be used to monitor the effectiveness of treatments for liver diseases.
Who performs an ALT blood test?
An ALT blood test is usually performed by a doctor or nurse. It is a simple procedure that only takes a few minutes.
Do I need to fast for an ALT blood test?
No, you do not need to fast for an ALT blood test. However, it is important to tell your doctor or nurse if you have recently eaten or taken any medications that could affect the results of the test.

What do the results of an ALT blood test mean?
The results of an ALT blood test will show the amount of ALT in your blood. The normal range for ALT is 10-40 units per liter (U/L). If your ALT is higher than normal, it may indicate liver damage or disease. If your ALT is lower than normal, it may indicate a healthy liver.
What does it mean if my alanine transaminase (ALT) is high?
If your ALT is higher than normal, it may indicate liver damage or disease. Your doctor may order additional tests to determine the cause of the elevated ALT.
What does it mean if my alanine transaminase (ALT) is low?
If your ALT is lower than normal, it may indicate a healthy liver. However, it is important to talk to your doctor to determine the cause of the low ALT.
Should I be worried if I have high or low alanine transaminase (ALT) test results?
It is important to talk to your doctor if you have high or low ALT test results. Your doctor may order additional tests to determine the cause of the abnormal results.
Do I need follow-up tests if my ALT results are abnormal?
Your doctor may order additional tests to determine the cause of the abnormal ALT results. These tests may include a liver biopsy, imaging tests, or blood tests.
