Frequently asked questions

What does low albumin mean?

It can reflect long-standing liver disease, malnutrition, ongoing inflammation, or protein leaking from the kidneys (nephrotic syndrome) or gut. The cause guides treatment.

Is albumin part of the liver function test?

Yes — albumin is included in the LFT, because the liver makes it. A falling albumin can indicate reduced liver synthesis over time.
