Understanding your AST (SGOT) results
The AST, or SGOT, test measures an enzyme found primarily in your liver, heart, and muscles. When cells in these organs experience stress or irritation, this enzyme is released into your bloodstream.
What is the normal AST (SGOT) range?
- India
- No India-specific national reference interval is published for this parameter; your lab's printed range is the most reliable comparison.
- International
- 10–40 U/L
Ranges vary by lab, method and equipment — the range printed on your own report is the one that applies to your result.

What does a high AST (SGOT) result mean?
A high level can mean injury to your liver cells, heart muscle, or the muscles you move with. It is worth discussing with your doctor.
What does a low AST (SGOT) result mean?
A low level is usually not a concern.
What affects your AST (SGOT) result?
Recent intense physical exercise, muscle trauma, alcohol consumption, and various herbal or dietary supplements can temporarily alter this result.
- Recent hard exercise
- Alcohol
- Some medicines
- Muscle injury or surgery
- Blood cells breaking in the sample
Frequently asked questions
- What does a high AST or SGOT result mean?
- A higher reading suggests possible strain or irritation in tissues like the liver, heart, or muscles. Your doctor will look at this alongside other blood markers and your medical history to understand the cause.
- Can working out cause my AST levels to go up?
- Yes, strenuous workouts or heavy lifting can temporarily leak this enzyme from your muscles into the blood. Doctors often take recent exercise into account when reviewing your lab work.
- Does this test only check the liver?
- No, this enzyme is present in several parts of the body, including your muscles, kidneys, and heart. Because it is not unique to the liver, doctors usually compare it with other enzymes to see where the change is coming from.
- What is AST (SGOT)?
- This enzyme helps cells convert amino acids for energy and is present in liver, heart, muscle, and kidney tissue. When any of those cells are damaged, the enzyme spills into the bloodstream. You have this test alongside ALT to check liver health and look for possible cell damage in your liver or other tissues.
- What is a normal liver and heart enzyme test range?
- A typical adult range is around 10–40 U/L. No India-specific national reference interval is published for this parameter; your lab's printed range is the most reliable comparison. Ranges vary by lab, method and equipment — the range printed on your own report is the one that applies to your result.
