Liver function tests

Liver function tests are blood tests that measure different substances produced by your liver. These
measurements give your healthcare provider important information about the overall health of your
liver and how well it’s working. A liver panel will often measure several substances in one blood
sample. It may include various enzymes, proteins and byproducts.

How do liver function tests work?
A healthcare provider draws a small amount of blood from a vein in your arm to test in the lab. They’ll
look for abnormally high or low levels of different substances. Often, they’ll want to compare levels of
different enzymes or proteins to each other. If the balance is off, that can help them understand better
what may be going on in your liver.
