SGOT (AST) normal range: understanding your liver test

SGOT, also called AST (aspartate aminotransferase), is an enzyme found in the liver and also in the heart, muscles and red blood cells. When these cells are irritated or damaged, more SGOT enters the blood. It is a standard part of the liver function test (LFT) and is almost always read together with SGPT. People get it checked for fatty liver, alcohol use, jaundice, long-term medicines or a routine health check. Because SGOT also comes from muscles, even a hard workout can raise it for a short time.

SGOT (AST) – Normal range chart

Level	Value (U/L)
Normal (adults)Labs vary; some use up to about 48	About 8 – 40 U/L
Mildly raisedOften fatty liver, alcohol or recent hard exercise	About 40 – 120 U/L
Clearly raisedShow a doctor soon	Above about 120 U/L
SGOT/SGPT ratioOnly a doctor can read the ratio with other results	No fixed normal value

Ranges differ a little from lab to lab.

What does my result mean?

SGOT (AST) SGOT 45 U/L

This is just above the usual range. It can follow hard exercise, alcohol or fatty liver; your doctor may simply repeat the test and look at SGPT too.

SGOT (AST) SGOT 80 U/L

This is about double the upper limit. Show it to your doctor, who will compare it with SGPT and other results and may advise more tests.

SGOT (AST) SGOT 150 U/L

This is clearly high and should be checked by a doctor soon. The cause may be in the liver, muscles or elsewhere, and only proper checking can tell.

What this test checks

The test measures the amount of AST enzyme in the blood, in units per litre (U/L). It is usually done as part of a liver function test with SGPT, bilirubin, albumin and other values. Doctors often advise it for people with diabetes, obesity, regular alcohol intake, hepatitis risk or long-term medicines. Healthy adults can check it once a year in a routine checkup; people with liver disease need it as often as their doctor advises.

Common reasons for a high value

Fatty liver or weight gain
Regular or heavy alcohol intake
Viral hepatitis or other liver problems
Some medicines and herbal products
Hard exercise, muscle injury or muscle disease
Less common: heart, thyroid or blood-related problems

How to prepare

Avoid hard exercise, gym workouts and alcohol for 24–48 hours before the test, as these can raise SGOT. If it is part of a liver function test, many labs suggest 8–10 hours of fasting (plain water is fine). Do not stop your regular medicines without asking your doctor.

When to see a doctor

See a doctor if SGOT is above the range printed on your report or stays high on a repeat test. See a doctor quickly if you also have yellow eyes, dark urine, pale stools, swelling of the belly or pain in the upper right belly. Chest pain, yellow eyes with confusion, or vomiting blood is an emergency – go to a hospital immediately.

SGOT (AST) – FAQs

What is the normal SGOT level?

In adults, SGOT is usually about 8–40 U/L, though each lab sets its own range. The range printed on your own report is the one that applies, and your doctor reads it together with SGPT and other values.

Can exercise increase SGOT?

Yes. SGOT is also found in muscles, so a heavy workout, long run or muscle injury can raise it for a few days. Tell your doctor about recent exercise; a repeat test after rest may be suggested.

What does an SGOT/SGPT ratio mean?

Doctors sometimes compare the two values because the pattern can give clues about the type of liver problem. The ratio alone does not give a diagnosis, so it should only be interpreted by your doctor with your full report.

How do I get the SGOT test at home?

Book a liver function test online. A trained person collects the blood sample at your home, it is tested at a partner lab, and the report is sent to you on WhatsApp and email.
