Aspartate Transaminase
AST
Description
"Aspartate Transaminase" (AST) test measures the amount of AST enzyme in your blood, which can increase with liver, heart, or muscle injury. It’s commonly used to evaluate liver health, especially when combined with ALT testing. Elevated AST may indicate hepatitis, liver strain, or tissue damage elsewhere. Doctors use this test to interpret symptoms like fatigue or jaundice and decide whether further testing or treatment is needed. Ongoing AST monitoring helps track liver recovery or signal worsening function.

Key Reasons For Testing
Liver Function Assessment: Measures AST levels to evaluate liver health and detect damage.
Liver Disease Diagnosis: Identifies conditions like hepatitis, cirrhosis, or fatty liver disease.
Muscle Injury Detection: Detects elevated AST levels linked to muscle damage or conditions like rhabdomyolysis.
Medication Monitoring: Tracks liver response to potentially hepatotoxic medications.

Important Note
Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.
Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
