Serum Glutamic-Oxaloacetic Transaminase/Aspartate aminotransferase (SGOT/AST)

The SGOT test is a blood test that’s part of a liver profile. It measures one of two liver enzymes, called serum glutamic-oxaloacetic transaminase. And also, an SGOT test (or AST test) evaluates how much of the liver enzyme is in the blood.

Why do you need to take this test?

The SGOT test is commonly used to help your doctor diagnose the status of your liver.

Preparation

It is a simple blood test that can be technically done without any special preparation. But still, there are a couple steps you can take to make the process easier.

Avoid taking any over-the-counter (OTC) medications, including acetaminophen (Tylenol), in the two days before your test. If you do take them, remember to tell your doctor. You should tell your doctor about all the medications you’re taking before they administer the test so that they can account for them when reading the results.

Drink plenty of water the night before your test, too. Staying hydrated will make it easier for your technician to draw your blood. Make sure you wear something that allows your forearm — preferably up to the elbow — to be easily accessible for the technician to draw blood from.

Result

You should have the results in about a day and the normal ranges are:

  • Males: 10 to 40 units/L
  • Females: 9 to 32 units/L

Your exact range may depend on which lab your doctor uses. Therefore, talk with her about the specifics of your case.
