SGPT is also called ALT or serum Glutamic-Pyruvic Transaminase. This enzyme is mainly found in your Liver, if damaged it will release more ALT into your bloodstream which will cause ALT levels to rise. Doctors often club the ALT test along with other liver tests.
Normally, ALT levels in the blood are low. If your liver is damaged, it will release more ALT into your blood and levels will rise. Doctors often conduct this test to make sure the liver is not damaged.
You don’t need any special preparation for the ALT/SGPT test. Your doctor might ask you to stop eating or drinking a few hours before the test.
Tell your doctor what prescription drugs or supplements you take. Some medicines can affect the results of this test.
Results for this test normally arrive within a day. A normal ALT test result can range from 7 to 55 units per liter (U/L). Levels are normally higher in men.
Slightly high ALT levels may be caused by:
Cirrhosis (long-term damage and scarring of the liver)
