Normal blood levels of albumin usually range between 3.6-5.1 g/dL (grams per deciliter).

Albumin is one of several tests routinely used to help detect and monitor liver damage. Liver function is typically evaluated by a panel of tests that help doctors distinguish among the many different possible causes of liver damage, which can range from alcohol abuse to hepatitis infection or the side effects of prescription or over-the-counter medications.
Albumin, which is produced by the liver, is the most abundant protein in plasma, the clear, liquid portion of blood. Albumin nourishes tissues, helps maintain the fluid balance of the blood, and transports other molecules, such as hormones, vitamins, and calcium, throughout the body. Albumin is also tested for in the urine, but because only small amounts of the protein are found in urine, the test is called microalbumin (both blood and urine measurements test for the same molecule; microalbumin is not a smaller version of regular albumin).
In the U.S. more than 2 million individuals have alcoholic liver damage and approximately10 million have been exposed to hepatitis viruses. Liver damage also results from reactions to prescription and over-the-counter medicines, as well as environmental toxins. More than 26 million Americans age 20 or older have chronic kidney disease and more than 525,000 are under treatment for end-stage renal disease. This includes approximately 370,000 dialysis patients and 160,000 people with functioning kidney transplants (nearly 85,000 patients are waiting for transplants).
