According to the CDC, liver disease is a growing concern worldwide.
What is a Liver Function Test?
A liver function test is a group of blood tests. These tests measure different chemicals and proteins in your blood. For example, they check levels of enzymes and bilirubin. High or low levels can show if your liver is healthy or not. Doctors use this test to spot liver damage or disease. The test is simple and quick. It is also called a liver panel or liver health check.
Why is a Liver Function Test Needed?
Doctors order a liver function test for many reasons. Sometimes, it is part of a routine health check. Other times, it helps find the cause of symptoms. For instance, if you have yellow skin or feel tired, your doctor may suggest this test. In addition, people with certain conditions need regular liver tests. These include hepatitis, heavy alcohol use, or taking medicines that affect the liver. The test can also track how well treatment is working.
