SGOT, also known as AST, is an enzyme found in the liver, heart, muscles, kidneys, and brain. It is released into the blood when these tissues are damaged. Although commonly used as a liver function marker, AST is not liver-specific and must be interpreted with other tests.
This test helps assess liver injury, muscle damage, and cardiac conditions.
Why Is This Test Recommended?SGOT testing is recommended for patients with suspected liver disease, alcohol use disorder, hepatitis, muscle injury, or unexplained fatigue and abdominal discomfort. It is often ordered along with SGPT (ALT).
What Do the Results Indicate?Elevated SGOT levels may indicate liver inflammation, muscle injury, heart disease, or hemolysis. The ratio of SGOT to SGPT provides additional diagnostic clues.
How Is the Test Performed and Prepared For?A blood sample is collected. Fasting may be advised. Alcohol consumption should be avoided before testing.
