Albumin level

Blood albumin

Albumin is the most abundant protein in the blood. It is produced in the liver. Albumin plays many roles in the body. It is responsible for maintaining blood pressure by keeping water in the vessels. It acts as a transporter for a number of substances, including various hormones and drugs. Low albumin levels in the blood are often the cause of edema.

Changes in albumin can be quantitative (a decrease or increase in albumin levels) or qualitative (an alteration in the protein itself).
