What's this test for?

This test is ideal if you're experiencing unexplained fatigue, weakness, or signs of potential liver problems like jaundice or abdominal pain. It helps detect liver damage from conditions like hepatitis, cirrhosis, or fatty liver disease, and can also identify heart muscle damage from a heart attack. Many people use this test when they have abnormal liver function tests or risk factors for liver disease and want to understand what's happening with their health.

How should I prepare for this test?

No special preparation is typically required for this test. You can eat and drink normally before your blood draw, and you don't need to fast. However, avoid excessive alcohol consumption for 24 hours before testing, as it can temporarily elevate AST levels and affect accuracy. Let the lab know about any medications or supplements you're taking, as some can influence results.

What's included in this test?

AST

This test measures Aspartate Aminotransferase (AST), an enzyme found primarily in your liver and heart, with smaller amounts in muscles and other organs. Elevated AST levels can indicate liver damage from conditions like hepatitis, cirrhosis, or fatty liver disease, and can also detect recent heart muscle injury such as a heart attack. When tissues containing AST are damaged or stressed, the enzyme is released into your bloodstream, making it a valuable marker for assessing liver and heart health.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your AST levels mean for your liver and heart health. These notes include personalized recommendations like lifestyle changes, dietary adjustments, limiting alcohol intake, or whether you should follow up with a hepatologist or cardiologist. You'll also get the standard lab report and can track your AST levels over time using our trends feature to monitor liver healing or treatment effectiveness.
When will I get my results?
Results are typically available within 1-2 business days after your blood sample reaches the lab. You'll receive an email notification when your results are ready to view securely online. If results show significant abnormalities, you may want to discuss them with your healthcare provider promptly for appropriate follow-up.
Who should consider getting this test?
This test is important for people with known or suspected liver disease, those who drink alcohol regularly, individuals taking medications that can affect the liver, and anyone experiencing symptoms like fatigue, abdominal pain, or jaundice. It's also useful for monitoring existing liver conditions, evaluating unexplained elevation in other liver enzymes, or assessing potential heart muscle damage after chest pain. People with hepatitis, fatty liver disease, or cardiovascular risk factors should consider regular monitoring.
What symptoms indicate I may need this test?
You may need this test if you're experiencing persistent fatigue, weakness, loss of appetite, nausea, or abdominal pain, especially in the upper right side. Other signs include yellowing of the skin or eyes (jaundice), dark urine, pale stools, unexplained weight loss, or easy bruising. If you've had chest pain or symptoms of a heart attack, or if you have risk factors like heavy alcohol use, obesity, diabetes, or hepatitis exposure, this test can help identify the underlying cause.
How can I naturally support my liver health?
Supporting liver health starts with limiting or avoiding alcohol consumption and maintaining a healthy weight through balanced nutrition and regular exercise. Eat a diet rich in fruits, vegetables, whole grains, and lean proteins while limiting processed foods, saturated fats, and added sugars. Stay hydrated, avoid unnecessary medications or supplements that can stress the liver, and be cautious with over-the-counter pain relievers. Regular physical activity and avoiding exposure to toxins and chemicals also help protect your liver.
What does high AST mean?
High AST levels typically indicate damage or stress to your liver, heart, or muscle tissues. Liver-related causes include hepatitis, cirrhosis, fatty liver disease, alcohol-related liver damage, or medication toxicity. Elevated AST can also result from a heart attack, strenuous exercise, muscle injury, or certain medical conditions affecting other organs. The degree of elevation and pattern with other liver enzymes helps your doctor determine the cause and severity.
How often should I retest my AST levels?
If you have liver disease or are monitoring treatment, your doctor may recommend retesting every 3-6 months or more frequently if levels are significantly elevated. For medication monitoring or chronic conditions, testing every 6-12 months is common once levels stabilize. If your initial test shows elevated AST, your doctor will typically retest within a few weeks along with other liver function tests to identify the cause and track changes. The frequency depends on your specific health situation and underlying conditions.
