What are Liver Enzymes?

Frequently Asked Questions

Q. Why do I need this screening?

A. If you are on cholesterol-lowering medication, including statins, fibrates, bile-acid resins, absorption inhibitors or nicotinic acid/niacin, it’s recommended your liver enzyme levels be checked regularly. Statin medications work by blocking the liver enzyme that is responsible for producing cholesterol. A side effect of some statins is elevated liver enzymes, indicating liver injury.

Q. Do I need this screening if I already get my blood tested by my doctor?

Ask your physician if he or she is specifically checking for elevated liver enzymes, or see if your laboratory report includes results for ALT and AST. It is recommended that your liver enzymes be tested at least once a year or as frequently as your doctor advises.
