Overview of the Aspartate Transaminase (AST) Blood Test
The Aspartate Transaminase (AST) test is a single-marker blood test measuring the level of aspartate transaminase, also known as aspartate aminotransferase. AST is an enzyme found in several tissues, with significant amounts present in the liver and skeletal muscle.
AST is commonly considered when reviewing liver health, abnormal liver blood results or possible muscle-related enzyme changes. Because AST is not specific to the liver, it is often most useful when interpreted alongside other laboratory markers such as ALT, GGT, bilirubin or creatine kinase, depending on the clinical situation.
This is a single-biomarker test, rather than a complete liver panel. An AST result alone cannot diagnose or exclude liver or muscle disease, and the result should always be interpreted in the context of symptoms, medical history, medications, recent exercise and other relevant investigations.
What Does the Aspartate Transaminase (AST) Check?
This test measures 1 biomarker.
Aspartate Transaminase (AST)
AST is an enzyme present in the liver, skeletal muscle, heart and other tissues. Levels in the blood may increase when cells containing AST are injured or stressed. Because AST can originate from more than one tissue, an abnormal result should not be interpreted as evidence of a liver condition without considering other markers and clinical information.
Who May Benefit From the Aspartate Transaminase (AST) ?
This test may be suitable for people who want to:
Check an individual liver-related enzyme – Measure AST without booking a larger panel.
Follow up a previous abnormal AST result – Compare the result with earlier blood tests where appropriate.
Investigate liver health concerns – Add laboratory information when liver health is being assessed.
Review changes after lifestyle adjustments – Track AST after changes involving alcohol intake, diet or exercise where clinically relevant.
Monitor treatment or medication-related concerns – Check AST where liver monitoring has been recommended by a clinician.
Explore possible muscle-related enzyme changes – AST can also be influenced by skeletal muscle activity or injury.
Take a preventative approach to health – Include AST within private health monitoring when appropriate.
Arrange a private blood test in London without waiting for a GP referral.
How to Prepare
Symptoms and Reasons to Consider the Aspartate Transaminase (AST)
You may wish to consider the Aspartate Transaminase (AST) if you are experiencing symptoms or concerns that may be linked with liver or muscle health. This test may be relevant if you have:
A previous raised AST result that you want to recheck.
Persistent fatigue or weakness alongside other reasons to investigate liver health.
Yellowing of the skin or eyes requiring investigation by a healthcare professional.
Dark urine or unusually pale stools occurring with other liver-related symptoms.
Reduced appetite or persistent nausea where liver investigations have been suggested.
Unexplained itching alongside concerns about liver or biliary health.
Muscle pain or weakness where muscle-related enzyme changes are being considered.
Monitoring of liver health while taking certain medications, or for routine follow-up on the advice of your GP or specialist.
Symptoms associated with liver or muscle problems are not specific to AST. AST can enter the bloodstream from different tissues, which is why clinicians frequently review it alongside other enzymes and laboratory findings rather than interpreting the number on its own.
These symptoms can have many possible causes. Your result should be interpreted alongside symptoms, medical history, medication use, recent exercise, alcohol intake and professional medical advice where appropriate. Seek prompt medical attention for severe or rapidly worsening symptoms.

Attend your appointment
A trained professional will collect your blood sample safely and efficiently.
Laboratory analysis
Your blood sample is analysed at an accredited laboratory using validated methods to measure Aspartate Aminotransferase (AST) levels.
Receive your results securely
Your laboratory report will be sent securely by email. GP consultation options are available remotely, at home, by AI-assisted review and in clinic if required.
When Will I Receive My Results?
Results are typically available within 1 day after the laboratory receives your sample.
Once laboratory analysis has been completed, your report will be sent securely by email.
Turnaround times begin when the laboratory receives your sample rather than when it is collected. Although most results are available within one day, occasional laboratory quality assurance procedures may extend turnaround times. Results outside the expected range should be reviewed with a GP or suitably qualified healthcare professional.
Understanding Your Results
Your report will include your Aspartate Aminotransferase (AST) result together with the laboratory reference range.
Reference ranges may vary slightly between laboratories because of differences in analytical methods. A result within the reference range does not always exclude liver or muscle conditions, while an elevated result does not automatically identify the underlying cause.
AST levels should always be interpreted alongside your symptoms, medical history, medications, alcohol intake, exercise levels and other laboratory tests, particularly ALT and other liver function markers. If you have concerns regarding your results, speak with your GP or another suitably qualified healthcare professional.
