A normal range for ALT is 4 to 36 U/L (units per liter). However, it's important to note that normal value ranges may vary slightly among different laboratories. Some labs use different measurements or may test different samples. It is essential to consult your healthcare provider to understand the meaning of your specific test results.
Factors that may affect ALT levels:
- Liver disease: ALT levels are elevated in liver diseases like hepatitis, cirrhosis, and fatty liver disease.
- Other conditions: Certain conditions, like muscle injury, heart attack, and pancreatitis, can also raise ALT levels.
- Medications: Some medications, such as statins and antibiotics, can cause an increase in ALT levels.
Interpreting ALT test results:
- Elevated ALT: If your ALT level is elevated, your doctor may order further tests to determine the cause.
- Normal ALT: A normal ALT level doesn't necessarily mean you don't have liver disease, especially if you have other risk factors.
Remember: Your doctor can provide the most accurate interpretation of your ALT test results based on your individual medical history and other factors.
