What does your liver do?Your liver has an important function in your body. It filters everything you eat or consume, such as food, alcohol and medicines. Your liver ensures, among other things, that waste products are processed, that nutrients are stored and released, and for the production of proteins.
What do we determine during the liver test?
ALT & ASTALT (alanine aminotransaminase) and AST (aspartate aminotransferase) are enzymes in the blood. Enzymes are proteins that help convert one substance into another substance. ALT is mainly present in the liver. AST is also found in other cells, such as in muscles and in the kidneys. These values show cell renewal in the liver and can demonstrate whether there is liver damage. When liver cells are damaged, ALT and AST can leak into the blood. In that case, these values in your blood rise.
Gamma-GTGamma-GT (gamma glutamyl transpeptidase) is an enzyme that can be found throughout the body, but mainly in the liver. As with ALT and AST, gamma-GT can enter the blood in a damaged liver. Elevated values can therefore be a sign of liver disease. Gamma-GT cannot demonstrate the specific cause of liver disease, which is why this test is often done together with other tests.
Alkaline phosphataseAlkaline phosphatase (AF) is also an enzyme and is used for the diagnosis of bone and liver diseases. Alkaline phosphatase occurs in various places in the body, including your liver and bones. This value can show whether there are abnormalities in the liver or bones. To distinguish between these two, the gamma-GT test is done. For example, when alkaline phosphatase is elevated and gamma-GT is not, bone damage is usually present. When both values are elevated, it is often a liver abnormality.
Bilirubin totalA bilirubin test measures the levels of bilirubin in your blood. This is made during the breakdown of red blood cells. Bilirubin passes through your liver and is converted there. Ultimately it is excreted through the intestines. Higher levels of bilirubin can indicate liver problems. A total bilirubin test is a combination of direct and indirect bilirubin.
When to opt for a liver test?A liver test is recommended in the following situations:
- To see if you have liver damage
- When you use medications that can damage the liver
- With excessive alcohol consumption
- With certain medical conditions, such as diabetes or anemia
- If you suspect liver infections, such as hepatitis
