What is ALT SGPT?

They include aspartate aminotransferase (AST or SGOT) and alanine aminotransferase (ALT or SGPT). These enzymes are normally contained within liver cells. If the liver is injured, the liver cells spill the enzymes into blood, raising the enzyme levels in the blood and signaling the liver damage. read more

ALT usually is done as part of a group of liver function tests called a liver panel. This panel also includes an aspartate aminotransferase (AST) test. AST is another liver enzyme. As with ALT, the levels of AST in your blood rise if your liver is damaged. Comparing ALT with AST levels gives your doctor more information about the health of your liver. read more

Normally ALT (SGPT) is found in the liver in large quantity. We can't say that this enzyme is located exclusively in the liver but it is concentrated in large quantity there. We can say that it serves as a fairly specific indicator of the status of liver. read more

The ALT test checks the level of alanine aminotransferase in the blood to see if the liver is healthy. Elevated levels of the enzyme could indicate damage caused by trauma or a disease process, such as cirrhosis or a strain of hepatitis, as stated by WebMD. read more
