Liver Function Test | LFT

Liver function tests are used to measure how well your liver is working. It measures the levels of liver enzymes and/or proteins in your blood.

Do I need a liver function test?

The liver filters toxins out of your system and helps use food that you consume to make energy. You provider may order a liver function test to make sure your liver is healthy. Common reasons for a liver function test include:

  • Part of a normal health check-up

  • To diagnose liver disease

  • To check for liver damage

  • To scan for liver infections, like hepatitis C

  • As a precaution if you are taking a medication that might affect the liver

What are the symptoms of liver disease?

  • Abdominal pain

  • Nausea

  • Vomiting

  • Yellowed skin

How is a liver test done?

A care team member will draw your blood into a vial, using a small needle. This vial will be sent to a lab where the blood will be tested for proteins and/or enzymes produced by the liver.

How do I prepare for a liver test?

Tell your health care provider about all medications and vitamins/supplements that you are taking. These could affect your liver function. Your doctor will inform you if you need to fast before this test.
