SGOT Test
If your doctor has recommended an SGOT test, you are likely wondering what it measures and why it matters. SGOT (serum glutamic-oxaloacetic transaminase), also called AST (aspartate aminotransferase), is an enzyme found in high concentrations in the liver, heart, and muscles. When cells in these tissues are damaged, SGOT leaks into the bloodstream, making it a useful marker for injury. This test is frequently included in routine health checkups and liver function panels, but it is rarely used alone to make a diagnosis. Instead, it provides one piece of the puzzle alongside other tests like ALT, ALP, and bilirubin.
What Is the SGOT Test (AST)?
SGOT stands for serum glutamic-oxaloacetic transaminase, an enzyme that helps the body process amino acids. The test measures the amount of SGOT in your blood. While it is often grouped under liver function tests (LFTs), SGOT is not specific to the liver alone—it is also present in heart muscle, skeletal muscles, kidneys, and red blood cells. For this reason, elevated levels require further investigation to pinpoint the source of damage.
In Bangladesh, the SGOT test is commonly ordered alongside ALT (alanine aminotransferase) because ALT is more specific to the liver. A higher AST-to-ALT ratio can sometimes give clues about the cause of liver injury, such as alcohol-related damage versus viral hepatitis.
Why Is the SGOT Test Ordered?
Doctors may recommend an SGOT test for several reasons:
- Routine health screening: As part of a comprehensive checkup or pre-employment medical examination.
- Symptoms of liver disease: Jaundice (yellowing of skin or eyes), dark urine, fatigue, nausea, abdominal swelling, or unexplained weight loss.
- Monitoring known liver conditions: Such as hepatitis B or C, fatty liver disease, or cirrhosis.
- Assessing medication side effects: Some drugs (e.g., statins, antitubercular agents, paracetamol overdose) can affect the liver.
- Evaluating alcohol-related liver damage: Especially in patients with a history of heavy alcohol use.
- Checking muscle injury: Although less common, SGOT can rise after significant muscle trauma or intense exercise.
How Is the Test Performed?
The SGOT test is a simple blood draw. A healthcare professional cleans the skin over a vein (usually in your arm) and inserts a small needle to collect a blood sample. The procedure takes just a few minutes. Most laboratories do not require fasting for this test, but some doctors may ask you to avoid food or certain medications beforehand if they are also checking other markers like blood sugar or cholesterol. Inform your doctor about all prescription and over-the-counter medicines, as some can influence results. No special preparation beyond that is usually needed.
Understanding SGOT Test Results
The normal range for SGOT (AST) in adults is typically 8 to 45 units per litre (U/L), although reference ranges vary slightly between laboratories. Results outside this range do not automatically mean serious illness—they must be interpreted in context.
High SGOT levels may be associated with:
- Liver cell damage (hepatitis, cirrhosis, fatty liver disease)
- Alcohol-related liver injury
- Heart muscle damage (e.g., heart attack)
- Muscle injury (trauma, strenuous exercise, myopathy)
- Medication side effects
Low SGOT levels are less common and may be seen in advanced liver disease or vitamin B6 deficiency, but low levels are rarely a concern on their own.
Importantly, SGOT alone cannot diagnose a specific condition. Doctors compare it with AST (another name for SGOT), ALT, ALP (alkaline phosphatase), GGT, and bilirubin to build a clearer picture. For example, an AST:ALT ratio >2.0 may suggest alcoholic liver disease, while a ratio <1.0 is more common in viral hepatitis. Your GP or a hepatologist (liver specialist) can help interpret your results.
SGOT Test Cost in Bangladesh
The cost of an SGOT test in Bangladesh varies depending on whether you choose a private diagnostic lab, a hospital, or an outpatient clinic. Many labs offer the test as part of a liver function panel at a reduced bundled price. Prices are indicative and may change; always confirm before your visit.
| Item | Approx. BDT Range | Notes |
|---|---|---|
| SGOT (AST) test – private lab | ৳200 – ৳800 | Single-test cost; often cheaper when part of a complete LFT panel (৳500–৳1,500 for full panel). |
| SGOT (AST) test – hospital (private or public) | ৳500 – ৳1,500 | Price may include consultation or processing fees; public hospitals may charge lower rates. |
| Liver function panel (includes SGOT, ALT, ALP, bilirubin, total protein) | ৳500 – ৳2,000 | Bundled tests offer better value; common in popular labs like Popular, Medinova, and others. |
Note: Prices are approximate and vary by city, lab reputation, and whether you opt for urgent or routine processing. Always check current rates with the lab or hospital beforehand.

When to See a Doctor About Your SGOT Results
If your SGOT level is outside the normal range, it is important to discuss the result with a qualified doctor. Do not attempt to interpret or treat the value on your own. See a general physician or a hepatologist (liver specialist) if:
- Your SGOT is elevated, especially if accompanied by jaundice, dark urine, pale stools, nausea, vomiting, or abdominal pain.
- You have a known liver condition (hepatitis, fatty liver) and your levels have changed from previous tests.
- You are taking medications that can affect the liver and your doctor wants to monitor their impact.
- You experience unexplained fatigue, weight loss, or loss of appetite.
A doctor will review your full medical history, perform a physical exam, and likely order additional tests (such as ALT, ALP, bilirubin, ultrasound) to determine the underlying cause. Early detection can make a significant difference in managing liver health.
Frequently Asked Questions
What is the difference between SGOT and SGPT?
SGOT (AST) and SGPT (ALT) are both liver enzymes, but they are found in different tissues. SGOT is present in the liver, heart, muscles, kidneys, and brain, while SGPT is mostly concentrated in the liver. Because of this, a high SGPT level is more specific to liver injury, whereas a high SGOT can also result from muscle or heart damage. Doctors often compare the SGOT/SGPT ratio to help narrow down the cause.
What is the normal range for SGOT?
Reference ranges vary by laboratory, but a typical normal SGOT (AST) level is between 10 and 40 units per liter (U/L). However, what is considered normal may differ slightly depending on the lab’s equipment and the patient’s age, sex, and muscle mass. Your test report will include the specific reference range used by that laboratory. Always discuss your results with your doctor.
Can certain medications or supplements affect SGOT levels?
Yes, several medications and supplements can raise SGOT levels. Common examples include statins (cholesterol-lowering drugs), acetaminophen (paracetamol) in high doses, certain antibiotics, nonsteroidal anti-inflammatory drugs (NSAIDs), and some herbal supplements like kava or comfrey. However, not everyone experiences this effect, and the elevation may be temporary. Do not stop any medication without consulting your doctor.
Do I need to fast before an SGOT test?
Fasting is not usually required for an SGOT test alone. However, if the test is part of a broader panel that includes blood sugar, cholesterol, or triglycerides, your doctor may ask you to fast for 8–12 hours. Always follow the specific instructions given by your healthcare provider or the laboratory.
If my SGOT is high, does it always mean liver damage?
No, a high SGOT level does not automatically indicate liver damage. Because SGOT is also found in the heart, skeletal muscles, kidneys, and brain, elevated levels can result from conditions such as a heart attack, muscle injury, strenuous exercise, or even a recent injection. Your doctor will interpret your SGOT result alongside other tests (like ALT, ALP, and bilirubin) and your symptoms to determine the underlying cause.
