Aspartate Aminotransferase AST Blood Test
Low-Cost AST Liver Enzyme Blood Test
The Aspartate Aminotransferase AST Blood Test measures the level of AST enzyme in the blood.
AST, also called SGOT, is an enzyme found in several tissues of the body, including the liver, muscles, heart, kidneys, pancreas, and other organs.
This test may be useful for liver enzyme screening, follow-up to abnormal liver results, medication monitoring, muscle-related follow-up, or provider-directed testing.
✔ Measures AST liver enzyme level
✔ Common liver-related blood test
✔ May help screen for liver or muscle-related enzyme changes
✔ Low-cost lab testing option
✔ Doctor's order included
✔ No insurance required
✔ Convenient online ordering
⏱ Typical turnaround: results are usually emailed in 1–3 days.
What Is AST?
AST stands for aspartate aminotransferase.
AST is an enzyme found in the liver and other body tissues. When cells are irritated, inflamed, or injured, AST may be released into the bloodstream.
Because AST is found in more than just the liver, AST results are usually interpreted with other tests such as ALT, ALP, bilirubin, GGT, CK, or a full liver panel.
What This Test Measures
This blood test measures the amount of AST enzyme in the blood.
- Test name: Aspartate Aminotransferase AST Blood Test
- Also known as: AST Test, SGOT Test, Aspartate Transaminase Test
- Sample type: Blood
- Purpose: Measures AST enzyme level
- Common use: Liver enzyme screening and provider-directed follow-up
Why Order an AST Blood Test?
An AST blood test may be ordered when a person or healthcare provider wants to check liver-related or tissue enzyme activity.
This test may be considered for:
- Liver enzyme screening
- Follow-up to abnormal liver panel results
- Medication or supplement monitoring when directed by a provider
- Alcohol-related liver health screening
- Hepatitis or infection-related follow-up when directed by a provider
- Muscle injury or strenuous exercise-related follow-up
- Customers who want low-cost direct access to lab testing without insurance
Low-Cost Liver Enzyme Testing
This AST test is a simple and affordable way to check one commonly ordered liver enzyme.
If your healthcare provider specifically requested AST, ordering this test directly may help reduce delays and avoid insurance billing.
If you need a broader liver evaluation, a hepatic function panel or comprehensive metabolic panel may be more useful because those panels include multiple liver-related markers.
Who May Consider This Test?
- People whose healthcare provider requested AST testing
- People following up on abnormal liver enzyme results
- People monitoring liver-related markers under medical guidance
- People taking medications or supplements that may affect liver enzymes
- People with alcohol use, hepatitis exposure, fatty liver concerns, or metabolic health concerns
- Customers who want low-cost testing without insurance billing
Common Reasons for Testing
- Fatigue or weakness
- Yellowing of the skin or eyes
- Dark urine or pale stools
- Abdominal discomfort
- Nausea or loss of appetite
- Follow-up to abnormal ALT, ALP, bilirubin, or liver panel results
- Medication, supplement, or alcohol-related monitoring
- Provider-directed liver or muscle enzyme evaluation
AST vs ALT
AST and ALT are both enzymes commonly reviewed in liver testing.
ALT is more specific to the liver, while AST can come from the liver, muscle, heart, and other tissues.
Because AST can come from different sources, healthcare providers often compare AST with ALT and other markers to better understand the pattern.
Important: AST Alone Does Not Show the Cause
AST is a helpful enzyme marker, but it does not identify the exact cause of an abnormal result by itself.
Abnormal AST may require repeat testing, a liver panel, hepatitis testing, GGT, CK muscle enzyme testing, medication review, imaging, or medical evaluation.
Exercise and Muscle Injury Note
Intense exercise, muscle injury, recent surgery, or muscle inflammation may affect AST levels because AST is also found in muscle tissue.
If your AST is abnormal, tell your healthcare provider about recent workouts, injuries, muscle pain, medications, alcohol use, and supplements.
Important Health Warning
If you have yellowing of the skin or eyes, severe abdominal pain, vomiting blood, black or bloody stools, confusion, fainting, severe weakness, chest pain, shortness of breath, severe muscle pain with dark urine, or any urgent medical concern, seek medical care promptly.
Do not use this test as a substitute for urgent medical evaluation, diagnosis, or treatment.
Screening and Lab Access Only
LabReqs and SchoolTiters provide access to lab testing. We do not diagnose liver disease, hepatitis, cirrhosis, muscle disease, heart disease, medication injury, or any medical condition.
This test may provide useful lab information, but results should be reviewed with a licensed healthcare provider, especially if symptoms are present, results are abnormal, or medication changes are being considered.
Important Limitations
- This test measures AST only.
- This test does not include ALT, ALP, bilirubin, GGT, CK, hepatitis testing, or a full liver panel unless ordered separately.
- AST may be elevated from liver-related or non-liver-related causes.
- Exercise, muscle injury, alcohol use, medications, supplements, and illness may affect results.
- A normal AST result does not rule out all liver or muscle conditions.
- Abnormal results may require additional testing or medical evaluation.
- Do not start, stop, or change medication based only on this test result.
Before Ordering
- Confirm that you need an AST blood test.
- If your provider requested a liver panel, order the full liver panel instead of AST alone.
- If your provider requested both AST and ALT, make sure both tests are ordered.
- Tell your provider about alcohol use, medications, supplements, recent intense exercise, muscle injury, and symptoms.
- If your result is abnormal, review it with a licensed healthcare provider.

Frequently Asked Questions
What does the AST Blood Test measure?
This test measures aspartate aminotransferase, also called AST or SGOT, in the blood.
Is AST a liver test?
AST is commonly used as a liver enzyme test, but it can also come from muscle, heart, and other tissues.
Is AST the same as ALT?
No. AST and ALT are different enzymes. ALT is more specific to the liver, while AST may come from several tissues.
Can this test diagnose liver disease?
No. AST provides enzyme information only. Diagnosis requires provider evaluation and may require additional testing.
Should I order a liver panel instead?
If you need a broader liver evaluation, a liver panel may be better because it usually includes AST, ALT, ALP, bilirubin, albumin, and protein markers.
Can exercise affect AST?
Yes. Intense exercise or muscle injury may raise AST because AST is found in muscle tissue.
Do I need to fast?
Fasting is usually not required unless your healthcare provider or lab instructions tell you otherwise. Drinking water before the blood draw is recommended.
Is a doctor's order included?
Yes. A doctor's order is included with this lab test.
