What does Serum Albumin Measure?
The serum albumin test measures the levels of albumin present in the blood. Albumin is a protein which is made by the liver. This protein makes up about 60% of the total protein in the blood and has various functions.
The role of albumin is to keep fluid from leaking out of blood vessels and give nourishment to tissues. It also helps in the transportation of hormones, vitamins, calcium, and other substances throughout the body. The levels of albumin protein may decrease if there is any interference in its production from the liver. These decreased levels can be due to other reasons such as increase in the breakdown of proteins, increase in loss of proteins via the kidneys, and in case there is blood dilution (expansion of plasma volume).
The main causes of low albumin protein include severe liver disease and kidney disease.
Interpreting Serum Albumin results

Reference range may vary from lab to lab*
