Risk Factors for Poor Liver Function

  • People taking statin medications
  • Diabetes
  • Obesity
  • Consume large amounts of alcohol
  • At risk for hepatitis

Liver Function Screening Details

Liver Function Screening determines if Alanine Aminotranferease (ALT) and Aspartate Aminotransferase (AST) enzymes are elevated in the blood. These enzymes, found in the liver, spill into circulating blood when liver cells are injured. Liver damage can be caused by hepatitis, alcohol consumption, diabetes, obesity, or statin-lowering medication.

About Liver Function

Because the liver is essential to digest food and rid the body of toxins, damage to the liver can ultimately lead to liver failure, a life-threatening condition. 

Warning Signs of Poor Liver Function

Liver function is critical to staying healthy, so consult a doctor if you observe these warning signs:
  • Skin and eyes that appear yellowish
  • Abdominal pain and swelling
  • Swelling in the legs and ankles

Liver Function Screening FAQ

  • Why do I need Liver Function Screening?
    Just like any disease, early detection allows you and your doctor to take action and slow the progression or mitigate your risk.
  • What are ALT and AST?
    ALT and AST are enzymes that are found in the liver. Damage to the liver causes these enzymes to spill into the bloodstream. These enzymes are often monitored closely in people taking statin-lowering medications.
  • What can damage the liver?
    Many things can damage the liver: hepatitis infection, alcohol consumption, diabetes, obesity, and statin-lowering medications.
