This test measures the amount of the protein albumin in your blood. Your liver makes albumin. Albumin carries substances such as hormones, medicines, and enzymes throughout your body. This test can help diagnose, evaluate, and watch kidney and liver conditions.
Your liver takes proteins from the foods you eat and turns them into new proteins that circulate to various organs and tissues in your body. A serum albumin test can tell your doctor how well your liver is working. It’s often one of the tests in a liver panel. In addition to albumin, a liver panel tests your blood for creatinine, blood urea nitrogen, and prealbumin.
The reference range for albumin testing is as follows: The normal range is 3.5 to 5.5 g/dL or 35-55 g/liter. This range may vary slightly in different laboratories. Albumin composes 50%-60% of blood plasma proteins.
