Test Description
The AST test measures the level of aspartate aminotransferase (AST), an enzyme found mostly in the liver but also in the heart, kidneys, muscles, and other organs. When these tissues are damaged, AST leaks into the bloodstream, causing elevated levels. This test helps detect liver injury or damage, as well as issues in other organs.
Indications of the Aspartate Transferase Test
The test is commonly ordered to:
Check for liver damage or liver diseases such as hepatitis, cirrhosis, or fatty liver disease.
Investigate unexplained symptoms such as jaundice, fatigue, abdominal pain, and dark urine.
Monitor ongoing liver conditions or effects of medications that may harm the liver.
Assess damage to heart or muscles when suspected.
Screen high-risk individuals (e.g., alcohol users, people with diabetes, obesity, or family history of liver disease).
Patient Preparation/Instructions
Fasting may be required for 8–12 hours if AST is tested as part of a liver panel or metabolic panel.
Inform your healthcare provider about any medications or supplements, as some may affect AST levels.
Avoid alcohol for at least 24 hours before the test.
Blood sample is usually collected from a vein in your arm.
Typical Reference Values
Males (14 years and older): 8 to 48 U/L
Females (14 years and older): 8 to 43 U/L
Children’s ranges may vary slightly with age and sex.
Elevated AST levels suggest liver or other organ damage; however, results must be interpreted with other tests and clinical information.
Time it takes to get Report
Results are commonly available within 1 to 2 hours after blood collection.
