Albumin test
Albumin is a protein produced by the liver that plays a critical role in maintaining the balance of fluids in the body. It is the most abundant protein in human plasma and helps to transport hormones, drugs, and other substances through the bloodstream. Albumin is also involved in regulating blood pressure, as well as the pH and electrolyte balance of the body.
An albumin test measures the level of albumin in a person's blood. The test is often ordered as part of a routine blood test or to evaluate liver function, kidney function, or nutritional status.
