Liver Function

Why have a liver function blood test?

A Liver Function Blood Test assesses liver health, detecting diseases like hepatitis or cirrhosis early. It monitors liver function in those with liver conditions or at risk due to alcohol use, obesity, or exposure to liver-damaging substances.

What is liver function?

Liver function involves filtering toxins from blood, producing bile for digestion, storing energy, and metabolizing medications. Maintaining liver health is crucial for overall well-being and preventing serious health issues.

Who may be at risk?

Individuals with hepatitis virus exposure, heavy alcohol use, obesity, family history of liver disease, or undergoing treatments affecting liver function are at higher risk of liver damage or dysfunction.

What are the symptoms?

Symptoms of liver damage include abdominal pain or swelling, jaundice (yellowing of skin or eyes), fatigue, nausea or vomiting, loss of appetite, dark urine, and easy bruising or bleeding.

How does the blood test work and what do my results mean?

A Liver Function Blood Test measures levels of enzymes (ALT, AST), bilirubin, albumin, and other markers. Elevated ALT or AST levels above 40 IU/L may indicate liver damage. Your healthcare provider interprets results to assess liver health, diagnose conditions, monitor disease progression, or adjust treatments as necessary. Regular testing helps manage liver disease and optimize overall health.


Having a liver function blood test is a key step in taking control of your health and preventing liver damage or dysfunction.
