For whom is such a test to be considered?
An ALT test is recommended for: Persons with symptoms such as fatigue, jaundice or abdominal pain Patients at risk of liver damage (e.g. due to alcohol abuse, hepatitis infections, medications) Monitoring of patients with known liver diseases Preventive examination in case of increased risk of fatty liver (e.g. overweight, diabetes)
What is it used for?
The test serves the diagnosis and monitoring of liver diseases such as hepatitis, fatty liver or cirrhosis. It helps to clarify the cause of unclear complaints and to detect liver damage at an early stage.
What can be inferred from that?
An elevated ALT value indicates damage to the liver cells, as in: Acute or chronic hepatitis Alcohol-induced liver damage Drug-induced liver damage Symptoms with elevated ALT can be: Fatigue, loss of appetite Jaundice, dark urine A low ALT value usually has no clinical significance.
