Albumins are one of the most common types of protein in the body and are found in the blood. They are water soluble and are present in the plasma of the blood. Serum albumin binds fatty acids, bilirubin, hormones, and thyroxine. They also regulate the blood pressure. They are produced in the liver and are the most abundant form of protein in blood plasma. They regulate the blood volume. A test called Serum Albumin is generally advised by doctors to assess and investigate liver and kidney disease. In people with diabetes, diabetic nephropathy is a complication, and for this reason this test may be advised to look out for kidney disease.
