What are liver function tests?

Definition of Liver Function Tests Liver function tests are a group of tests used to evaluate the health of the liver and its ability to perform its functions. These tests include measuring the levels of a group of enzymes and proteins in the blood, such as albumin, blood globulin, and the enzymes ALT and AST. The importance of liver function tests The importance of liver function tests lies in their ability to detect any health problems that the liver may suffer from, including infections, cirrhosis, and biliary diseases. The results provide a comprehensive view of the condition of the liver, which helps doctors make appropriate decisions about the treatment and care needed to maintain overall health.

Types of liver function tests

Common Liver Function Tests Common liver function tests include measuring basic liver enzymes such as ALT and AST, as well as albumin levels, which are common indicators of liver health. These tests involve taking a blood sample and analyzing it to determine if there are any signs of liver damage or inflammation. Specialized Liver Function Tests There are also more specialized tests such as the prothrombin time test, which helps evaluate the liver’s ability to produce proteins responsible for blood clotting. This test is used in certain cases to determine the severity of various liver conditions.

How to perform liver function tests

Preparing for Tests Before having liver function tests, a person should make sure that they are not taking any medications or supplements that might affect the results. It is also important to inform the doctor of any pre-existing health conditions. The patient may be asked to fast the night before the test to improve the accuracy of the results. Procedures During the Test The test procedure begins with taking a blood sample using a fine needle. The blood is drawn from a vein, and is usually a quick and painless process. After the sample is taken, it is sent to a lab for analysis. It may take several days to get the results.

These results indicate that liver enzymes and other levels of vital compounds are within healthy limits, reflecting the good health of the liver. How to understand abnormal results If the results are abnormal, further investigation may be required. Elevated levels of some enzymes may indicate inflammation or damage to the liver. The patient should discuss the results with his doctor to determine the possible causes and appropriate treatment methods, which will help to take care of the health of the liver effectively.
