SGOT / AST Test
The SGOT (Serum Glutamic Oxaloacetic Transaminase) test, also commonly known as AST (Aspartate Aminotransferase), is a vital diagnostic tool used primarily to assess liver health and detect organ damage. When cells in the liver, heart, or muscles are injured, they leak this enzyme into the bloodstream; therefore, measuring its levels helps clinicians identify conditions such as hepatitis, cirrhosis, or even recent myocardial infarctions (heart attacks). It is particularly helpful for monitoring the side effects of medications that may be toxic to the liver or for evaluating patients exhibiting symptoms like jaundice, fatigue, or abdominal pain, allowing for early intervention before significant permanent damage occurs.

Why SGOT Levels Matter for Liver Health
The liver is regarded as one of the most important organs in the body, as it is responsible for filtering toxins, breaking down food, and producing essential proteins. When liver cells are damaged, an enzyme called SGOT (Serum Glutamic Oxaloacetic Transaminase) also known as AST (Aspartate Aminotransferase) is released into the bloodstream. Because of this, the SGOT/AST test is widely used to detect liver damage and to monitor overall liver function.
This enzyme is not found in the liver alone. It is also present in the heart and muscle tissues, which is why elevated SGOT levels are sometimes linked with heart conditions or muscle injury as well. When the test is ordered, it is usually recommended alongside SGPT (ALT), since both enzymes are read together to get a clearer picture of liver health.
Why is this test recommended?
The SGOT/AST test is generally recommended when symptoms such as unexplained fatigue, yellowing of the skin or eyes (jaundice), abdominal pain, nausea, or dark-coloured urine are experienced. It is also advised for individuals who consume alcohol regularly, those who are on medications that may affect the liver, and people being monitored for existing liver conditions such as hepatitis or fatty liver disease. In many cases, this test is included as part of a routine health checkup, even when no symptoms are present, so that liver health can be tracked over time.
