What is albumin?

Section 1 / 4

By Donna Swartzendruber, MSN, RN, CNN

Albumin is the most common protein found in the blood. It provides the body with the protein needed to both maintain growth and repair tissues. During a dialysis treatment, the albumin in your blood also helps with fluid removal. It helps "pull" extra fluid from swollen tissues back into the blood, where it can then be removed by the dialyzer.

Kidney Disease Outcomes Quality Initiative (KDOQI) guidelines, from the National Kidney Foundation, recommend that a blood albumin level be 4.0 g/dl. or higher. That is also DaVita's recommendation.
