What is the full form of SGPT
SGPT: Serum Glutamic Pyruvic Transaminase
SGPT stands for Serum Glutamic Pyruvic Transaminase. It is an enzyme which is now known as Alanine aminotransferase (ALT). It is produced by the liver. So, it is found in high concentrations in liver cells and in moderate concentrations in kidney cells and in low concentrations in heart, pancreas, spleen, red blood cells and skeletal muscles.
It is released into the blood when the liver or the other organs that contain ALT are damaged. So, whenever there is damage to liver, the levels of ALT may increase as much as 50 times than the normal levels in the blood.
The ALT test is a sensitive test for evaluating liver function. It checks and measures damage to the liver. It is also done to check medical treatments that may affect the liver. ALT is a simple test in which a small amount of blood is taken from a vein in your arm with a needle and collected in a tube then sent to a lab. ALT is also a part of a group of tests known as LFTs (liver function tests) used to test liver function.
The ALT test is done if a patient has symptoms of liver disease:
Some of the common reasons for a higher than normal ALT level are given below:
Risks associated with an ALT test:
Although ALT is a simple blood test, it may involve a few risks. For example, it may cause bruising in the area where the needle was inserted. However, bruising can be reduced by applying pressure to the site of injection for a few minutes after the needle is removed. In some cases, some other complications may occur, such as:
ALT test results:
The normal level of ALT in blood for males ranges from 29 to 33 units per liter and for females 19 to 25 units per liter. This value can be affected by the age of the patient. If the levels of ALT are higher than this range, there may be a liver disorder.
