Alanine Transaminase (ALT) Blood Test Explained
 
 
The Alanine Transaminase (ALT) blood test is an excellent measure of how well your liver is functioning.  Following is a sample of the results of the Alanine Transaminase (ALT) blood test. The reference interval indicates the normal ranges and the flag indicates a result outside of those ranges.
 
 
 
 
The ALT blood test is performed to determine if the liver is damaged or diseased.  ALT is found normally in low levels in the blood.  However, if the liver is damaged ALT levels rise as the lever releases ALT into the blood.

Average levels of ALT in males:      10-40 units / liter  

Average levels of ALT in females:      7-35 units / liter  

High levels of ALT in the blood may indicate liver damage caused by hepatitis, lead poisoning, drug reactions, alcohol abuse, or mononucleosis. Medicines such as statins, antibiotics, aspirin, narcotics, and chemotherapy can also cause elevated ALT levels.
