Know what is Liver function Test?
by GoMedii Technologies Health ConsultantThe liver function test is a type of blood test used to check for liver disease and any kind of damage. This test measures the number of certain enzymes and proteins in the blood.
Some tests are done to find out how well the liver is doing its normal job of making protein and cleansing the blood's waste material, bilirubin. Some other liver tests measure enzymes that are released by liver cells because of disease or damage.
Abnormal liver tests do not necessarily indicate liver disease. Your doctor will explain the result very well.

Why is the liver function test done?
A liver function test is performed to find out:
Detection of liver infections such as hepatitis
Monitoring of a disease such as viral and alcoholic hepatitis. Also to find out how well the disease is being treated.
Measuring the severity of a disease, especially liver wounds (cirrhosis).
Monitoring the side effects of medicines.
The liver function test measures the levels of certain enzymes and proteins in your blood. These levels are more or less normal than normal, indicating liver problems. Some common liver function tests include:
Alanine Transaminase (ALT). ALT is an enzyme found in the liver that helps the body in the metabolic metabolism of proteins. When the liver is damaged, ALT is released into the blood, increasing its level.
Aspartate transaminase (AST). AST is an enzyme that helps metabolize alanine, alanine is an amino acid. Just like ALT, AST is present in small amounts in the blood, but its level increases when the liver or muscles are damaged.
Alkaline phosphates (ALP). ALP is an enzyme found in the liver, bile ducts, and bones. Excess of this can be a sign of liver disease such as blockage in the bile ducts or some bone disease.

Albumin and Total Protein. Albumin is one of the many proteins made in the liver. These proteins are needed to protect the body from infection and for other functions. Lower than normal levels of albumin and total protein can be a sign of liver damage or disease.
Bilirubin is a waste normally formed during the breakdown of red blood cells. It passes through the liver through the feces. High levels of bilirubin can be a sign of liver disease, damage, or any type of anemia.
Gamma-Glutamyltransferase (GGT). GGT is an enzyme found in the blood. Its increased volume may indicate liver or bile duct damage.
L-lactate dehydrogenase (LD). LD is an enzyme present in the liver. Its high levels can be a sign of a damaged liver, although it can also increase due to other diseases.
Prothrombin time (PT). PT is the time when your blood clot forms. An increased amount may indicate liver damage, but it can also be aggravated by certain medications, such as warfarin, taken to thin the blood.
