AST (SGOT)
AST (aspartate aminotransferase) is an enzyme found in the liver, heart, and muscles. It is released into the bloodstream when these tissues are damaged.
Category: Liver Function
Also known as: ast, sgot, aspartate aminotransferase, aspartate transaminase, got, Aspartate amino transferase, Glutamic oxaloacetic transaminase, aspartat aminotransferaza
Reference range: 10–40 U/L (Source: ABIM)
Standard unit: U/L
High values may indicate
High AST may indicate liver damage from hepatitis or cirrhosis, heart attack, muscle injury, or medication toxicity. It is often evaluated alongside ALT.
Low values may indicate
Low AST is generally not a clinical concern. Very low levels may occasionally be associated with vitamin B6 deficiency or uremia.
Frequently asked questions
- What is a normal AST (SGOT) level?
- A typical reference range for AST (SGOT) is 10–40 U/L (source: ABIM). Reference ranges vary by laboratory, age, and sex, so always compare against the range on your own lab report.
- What units is AST (SGOT) measured in?
- AST (SGOT) is most commonly reported in U/L. Labs in different countries may use other units — you can convert between them with BloodId's blood test unit converter.
- Where do AST (SGOT) reference ranges come from?
- BloodId uses ABIM standard reference ranges and educational information from MedlinePlus (see our methodology). Reference ranges still vary by lab, age, and sex, so always compare against your own report.
- Can I track AST (SGOT) over time?
- Yes. Upload results from any lab and BloodId charts your AST (SGOT) over time against its reference range, so you can see whether the trend is rising, falling, or stable.
