Which Key Indicators Should Be Primarily Examined in Liver Function Tests?

Liver function tests primarily focus on indicators such as Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST), Bilirubin, Albumin, and Prothrombin Time. If abnormalities are detected in liver function, it is recommended to seek medical attention promptly and follow the doctor's treatment advice.

1. Alanine Aminotransferase (ALT)

ALT is an enzyme found in the liver. When the liver is damaged, it is released into the bloodstream, resulting in elevated ALT levels in the blood.

2. Aspartate Aminotransferase (AST)

AST is another enzyme present in the liver, and its elevation typically indicates liver damage.

3. Bilirubin

Bilirubin is a yellow substance produced by the breakdown of red blood cells. Normally, the liver processes and eliminates bilirubin from the body. Elevated bilirubin levels in the blood may suggest that the liver is unable to process bilirubin effectively.

4. Albumin

Albumin is a major plasma protein produced by the liver. A decrease in albumin levels in the blood may indicate impaired liver function.

5. Prothrombin Time (PT)

PT is a blood clotting test. The liver produces clotting factors, and prolongation of PT may suggest liver dysfunction.

In daily life, it is essential to protect liver function by avoiding excessive alcohol consumption, high fat and salt intake, and exposure to harmful chemicals. Maintaining good sleep and rest habits, avoiding late nights and overexertion, can effectively safeguard liver health and prevent liver function abnormalities.
